RFC6682 - RTP Payload Format for Raptor Forward Error Correction (FEC)
This document specifies an RTP payload format for the Forward Error Correction (FEC) repair data produced by the Raptor FEC Schemes. Raptor FEC Schemes are specified for use with the IETF FEC Framework that supports the transport of repair data over both UDP and RTP. This document specifies the payload format that is required for the use of RTP to carry Raptor repair flows. [STANDARDS-TRACK]
RFC6681 - Raptor Forward Error Correction (FEC) Schemes for FECFRAME
This document describes Fully-Specified Forward Error Correction (FEC) Schemes for the Raptor and RaptorQ codes and their application to reliable delivery of media streams in the context of the FEC Framework. The Raptor and RaptorQ codes are systematic codes, where a number of repair symbols are generated from a set of source symbols and sent in one or more repair flows in addition to the source symbols that are sent to the receiver(s) within a source flow. The Raptor and RaptorQ codes offer close to optimal protection against arbitrary packet losses at a low computational complexity. Six FEC Schemes are defined: two for the protection of arbitrary packet flows, two that are optimized for small source blocks, and two for the protection of a single flow that already contains a sequence number. Repair data may be sent over arbitrary datagram transport (e.g., UDP) or using RTP. [STANDARDS-TRACK]
RFC6680 - Generic Security Service Application Programming Interface (GSS-API) Naming Extensions

RFC6679 - Explicit Congestion Notification (ECN) for RTP over UDP
This memo specifies how Explicit Congestion Notification (ECN) can be used with the Real-time Transport Protocol (RTP) running over UDP, using the RTP Control Protocol (RTCP) as a feedback mechanism. It defines a new RTCP Extended Report (XR) block for periodic ECN feedback, a new RTCP transport feedback message for timely reporting of congestion events, and a Session Traversal Utilities for NAT (STUN) extension used in the optional initialisation method using Interactive Connectivity Establishment (ICE). Signalling and procedures for negotiation of capabilities and initialisation methods are also defined. [STANDARDS-TRACK]
RFC6678 - Requirements for a Tunnel-Based Extensible Authentication Protocol (EAP) Method
This memo defines the requirements for a tunnel-based Extensible Authentication Protocol (EAP) Method. This tunnel method will use Transport Layer Security (TLS) to establish a secure tunnel. The tunnel will provide support for password authentication, EAP authentication, and the transport of additional data for other purposes.

This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6675 - A Conservative Loss Recovery Algorithm Based on Selective Acknowledgment (SACK) for TCP
This document presents a conservative loss recovery algorithm for TCP that is based on the use of the selective acknowledgment (SACK) TCP option. The algorithm presented in this document conforms to the spirit of the current congestion control specification (RFC 5681), but allows TCP senders to recover more effectively when multiple segments are lost from a single flight of data. This document obsoletes RFC 3517 and describes changes from it. [STANDARDS-TRACK]
RFC6674 - Gateway-Initiated Dual-Stack Lite Deployment
Gateway-Initiated Dual-Stack Lite (GI-DS-Lite) is a variant of Dual- Stack Lite (DS-Lite) applicable to certain tunnel-based access architectures. GI-DS-Lite extends existing access tunnels beyond the access gateway to an IPv4-IPv4 NAT using softwires with an embedded Context Identifier that uniquely identifies the end-system to which the tunneled packets belong. The access gateway determines which portion of the traffic requires NAT using local policies and sends/ receives this portion to/from this softwire. [STANDARDS-TRACK]
RFC6673 - Round-Trip Packet Loss Metrics
Many user applications (and the transport protocols that make them possible) require two-way communications. To assess this capability, and to achieve test system simplicity, round-trip loss measurements are frequently conducted in practice. The Two-Way Active Measurement Protocol specified in RFC 5357 establishes a round-trip loss measurement capability for the Internet. However, there is currently no round-trip packet loss metric specified according to the RFC 2330 framework.
RFC6672 - DNAME Redirection in the DNS
The DNAME record provides redirection for a subtree of the domain name tree in the DNS. That is, all names that end with a particular suffix are redirected to another part of the DNS. This document obsoletes the original specification in RFC 2672 as well as updates the document on representing IPv6 addresses in DNS (RFC 3363). [STANDARDS-TRACK]
RFC6671 - Allocation of a Generic Associated Channel Type for ITU-T MPLS Transport Profile Operation, Maintenance, and Administration (MPLS-TP OAM)
This document assigns a Generic Associated Channel (G-ACh) Type for carrying ITU-T MPLS Transport Profile Operations, Administration, and Management (MPLS-TP OAM) messages in the MPLS Generic Associated Channel. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6670 - The Reasons for Selecting a Single Solution for MPLS Transport Profile (MPLS-TP) Operations, Administration, and Maintenance (OAM)
The MPLS Transport Profile (MPLS-TP) is a profile of the MPLS technology for use in transport network deployments. The work on MPLS-TP has extended the MPLS technology with additional architectural elements and functions that can be used in any MPLS deployment. MPLS-TP is a set of functions and features selected from the extended MPLS toolset and applied in a consistent way to meet the needs and requirements of operators of packet transport networks.
RFC6669 - An Overview of the Operations, Administration, and Maintenance (OAM) Toolset for MPLS-Based Transport Networks
This document provides an overview of the Operations, Administration, and Maintenance (OAM) toolset for MPLS-based transport networks. The toolset consists of a comprehensive set of fault management and performance monitoring capabilities (operating in the data plane) that are appropriate for transport networks as required in RFC 5860 and support the network and services at different nested levels. This overview includes a brief recap of the MPLS Transport Profile (MPLS-TP) OAM requirements and functions and the generic mechanisms created in the MPLS data plane that allow the OAM packets to run in-band and share their fate with data packets. The protocol definitions for each of the MPLS-TP OAM tools are defined in separate documents (RFCs or Working Group documents), which are referenced by this document. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6668 - SHA-2 Data Integrity Verification for the Secure Shell (SSH) Transport Layer Protocol
This memo defines algorithm names and parameters for use in some of the SHA-2 family of secure hash algorithms for data integrity verification in the Secure Shell (SSH) protocol. It also updates RFC 4253 by specifying a new RECOMMENDED data integrity algorithm. [STANDARDS-TRACK]
RFC6667 - LDP 'Typed Wildcard' Forwarding Equivalence Class (FEC) for PWid and Generalized PWid FEC Elements
The "Typed Wildcard Forwarding Equivalence Class (FEC) Element" defines an extension to the Label Distribution Protocol (LDP) that can be used when requesting, withdrawing, or releasing all label bindings for a given FEC Element type is desired. However, a Typed Wildcard FEC Element must be individually defined for each FEC Element type. This specification defines the Typed Wildcard FEC Elements for the Pseudowire Identifier (PWid) (0x80) and Generalized PWid (0x81) FEC Element types. [STANDARDS-TRACK]
RFC6666 - A Discard Prefix for IPv6
Remote triggered black hole filtering describes a method of mitigating the effects of denial-of-service attacks by selectively discarding traffic based on source or destination address. Remote triggered black hole routing describes a method of selectively re- routing traffic into a sinkhole router (for further analysis) based on destination address. This document updates the "IPv6 Special Purpose Address Registry" by explaining why a unique IPv6 prefix should be formally assigned by IANA for the purpose of facilitating IPv6 remote triggered black hole filtering and routing. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6665 - SIP-Specific Event Notification
This document describes an extension to the Session Initiation Protocol (SIP) defined by RFC 3261. The purpose of this extension is to provide an extensible framework by which SIP nodes can request notification from remote nodes indicating that certain events have occurred.
RFC6664 - S/MIME Capabilities for Public Key Definitions
This document defines a set of Secure/Multipurpose Internet Mail Extensions (S/MIME) Capability types for ASN.1 encoding for the current set of public keys defined by the PKIX working group. This facilitates the ability for a requester to specify information on the public keys and signature algorithms to be used in responses. "Online Certificate Status Protocol Algorithm Agility" (RFC 6277) details an example of where this is used. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6663 - Requirements for Signaling of Pre-Congestion Information in a Diffserv Domain
Pre-Congestion Notification (PCN) is a means for protecting quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo describes the requirements for the signaling applied within the PCN-domain: (1) PCN-feedback-information is carried from the PCN-egress-node to the Decision Point; (2) the Decision Point may ask the PCN-ingress-node to measure, and report back, the rate of sent PCN-traffic between that PCN-ingress-node and PCN-egress-node. The Decision Point may be either collocated with the PCN-ingress-node or a centralized node (in the first case, (2) is not required). The signaling requirements pertain in particular to two edge behaviors, Controlled Load (CL) and Single Marking (SM). This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6662 - Pre-Congestion Notification (PCN) Boundary-Node Behavior for the Single Marking (SM) Mode of Operation
Pre-Congestion Notification (PCN) is a means for protecting the quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo is one of a series describing possible boundary-node behaviors for a PCN-domain. The behavior described here is that for a form of measurement-based load control using two PCN marking states: not- marked and excess-traffic-marked. This behavior is known informally as the Single Marking (SM) PCN-boundary-node behavior. This document defines an Experimental Protocol for the Internet community.
RFC6661 - Pre-Congestion Notification (PCN) Boundary-Node Behavior for the Controlled Load (CL) Mode of Operation
Pre-Congestion Notification (PCN) is a means for protecting the quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo is one of a series describing possible boundary-node behaviors for a PCN-domain. The behavior described here is that for a form of measurement-based load control using three PCN marking states: not- marked, threshold-marked, and excess-traffic-marked. This behavior is known informally as the Controlled Load (CL) PCN-boundary-node behavior. This document defines an Experimental Protocol for the Internet community.
RFC6660 - Encoding Three Pre-Congestion Notification (PCN) States in the IP Header Using a Single Diffserv Codepoint (DSCP)
The objective of Pre-Congestion Notification (PCN) is to protect the quality of service (QoS) of inelastic flows within a Diffserv domain. The overall rate of PCN-traffic is metered on every link in the PCN- domain, and PCN-packets are appropriately marked when certain configured rates are exceeded. Egress nodes pass information about these PCN-marks to Decision Points that then decide whether to admit or block new flow requests or to terminate some already admitted flows during serious pre-congestion.
RFC6659 - Considerations for Deploying the Rapid Acquisition of Multicast RTP Sessions (RAMS) Method
The Rapid Acquisition of Multicast RTP Sessions (RAMS) solution is a method based on RTP and the RTP Control Protocol (RTCP) that enables an RTP receiver to rapidly acquire and start consuming the RTP multicast data. Upon a request from the RTP receiver, an auxiliary unicast RTP retransmission session is set up between a retransmission server and the RTP receiver, over which the reference information about the new multicast stream the RTP receiver is about to join is transmitted at an accelerated rate. This often precedes, but may also accompany, the multicast stream itself. When there is only one multicast stream to be acquired, the RAMS solution works in a straightforward manner. However, when there are two or more multicast streams to be acquired from the same or different multicast RTP sessions, care should be taken to configure each RAMS session appropriately. This document provides example scenarios and discusses how the RAMS solution could be used in such scenarios. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6658 - Packet Pseudowire Encapsulation over an MPLS PSN
This document describes a pseudowire mechanism that is used to transport a packet service over an MPLS PSN in the case where the client Label Switching Router (LSR) and the server Provider Edge equipments are co-resident in the same equipment. This pseudowire mechanism may be used to carry all of the required layer 2 and layer 3 protocols between the pair of client LSRs. [STANDARDS-TRACK]
RFC6657 - Update to MIME regarding "charset" Parameter Handling in Textual Media Types
This document changes RFC 2046 rules regarding default "charset" parameter values for "text/*" media types to better align with common usage by existing clients and servers. [STANDARDS-TRACK]
RFC6656 - Description of Cisco Systems' Subnet Allocation Option for DHCPv4
This memo documents a DHCPv4 option that currently exists and was previously privately defined for the operation and usage of the Cisco Systems' Subnet Allocation Option for DHCPv4. The option is passed between the DHCPv4 Client and the DHCPv4 Server to request dynamic allocation of a subnet, give specifications of the subnet(s) allocated, and report usage statistics. This memo documents the current usage of the option in agreement with RFC 3942, which declares that any preexisting usages of option numbers in the range 128-223 should be documented and that the working group will try to officially assign those numbers to those options. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6655 - AES-CCM Cipher Suites for Transport Layer Security (TLS)
This memo describes the use of the Advanced Encryption Standard (AES) in the Counter with Cipher Block Chaining - Message Authentication Code (CBC-MAC) Mode (CCM) of operation within Transport Layer Security (TLS) and Datagram TLS (DTLS) to provide confidentiality and data origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments. [STANDARDS-TRACK]
RFC6654 - Gateway-Initiated IPv6 Rapid Deployment on IPv4 Infrastructures (GI 6rd)
This document proposes an alternative IPv6 Rapid Deployment on IPv4 Infrastructures (6rd) deployment model to that of RFC 5969. The basic 6rd model allows IPv6 hosts to gain access to IPv6 networks across an IPv4 access network using 6-in-4 tunnels. 6rd requires support by a device (the 6rd customer edge, or 6rd-CE) on the customer site, which must also be assigned an IPv4 address. The alternative model described in this document initiates the 6-in-4 tunnels from an operator-owned Gateway collocated with the operator's IPv4 network edge rather than from customer equipment, and hence is termed "Gateway-initiated 6rd" (GI 6rd). The advantages of this approach are that it requires no modification to customer equipment and avoids assignment of IPv4 addresses to customer equipment. The latter point means less pressure on IPv4 addresses in a high-growth environment. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6653 - DHCPv6 Prefix Delegation in Long-Term Evolution (LTE) Networks
As interest in IPv6 deployment in cellular networks increases, several migration issues have been being raised; IPv6 prefix management is the issue addressed in this document. Based on the idea that DHCPv6 servers can manage prefixes, we use DHCPv6 Prefix Delegation to address such prefix management issues as an access router offloading delegation of prefixes and release tasks to a DHCPv6 server. The access router first requests a prefix for an incoming mobile node from the DHCPv6 server. The access router may next do stateless or stateful address allocation to the mobile node, e.g., with a Router Advertisement or using DHCP. We also describe prefix management using Authentication, Authorization, and Accounting (AAA) servers. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6652 - Sender Policy Framework (SPF) Authentication Failure Reporting Using the Abuse Reporting Format
This memo presents extensions to the Abuse Reporting Format (ARF) and Sender Policy Framework (SPF) specifications to allow for detailed reporting of message authentication failures in an on-demand fashion.
RFC6651 - Extensions to DomainKeys Identified Mail (DKIM) for Failure Reporting

RFC6650 - Creation and Use of Email Feedback Reports: An Applicability Statement for the Abuse Reporting Format (ARF)
RFC 5965 defines an extensible, machine-readable format intended for mail operators to report feedback about received email to other parties. This applicability statement describes common methods for utilizing this format for reporting both abuse and authentication failure events. Mailbox Providers of any size, mail-sending entities, and end users can use these methods as a basis to create procedures that best suit them. Some related optional mechanisms are also discussed. [STANDARDS-TRACK]
RFC6649 - Deprecate DES, RC4-HMAC-EXP, and Other Weak Cryptographic Algorithms in Kerberos
The Kerberos 5 network authentication protocol, originally specified in RFC 1510, can use the Data Encryption Standard (DES) for encryption. Almost 30 years after first publishing DES, the National Institute of Standards and Technology (NIST) finally withdrew the standard in 2005, reflecting a long-established consensus that DES is insufficiently secure. By 2008, commercial hardware costing less than USD 15,000 could break DES keys in less than a day on average. DES is long past its sell-by date. Accordingly, this document updates RFC 1964, RFC 4120, RFC 4121, and RFC 4757 to deprecate the use of DES, RC4-HMAC-EXP, and other weak cryptographic algorithms in Kerberos. Because RFC 1510 (obsoleted by RFC 4120) supports only DES, this document recommends the reclassification of RFC 1510 as Historic. This memo documents an Internet Best Current Practice.
RFC6648 - Deprecating the "X-" Prefix and Similar Constructs in Application Protocols
Historically, designers and implementers of application protocols have often distinguished between standardized and unstandardized parameters by prefixing the names of unstandardized parameters with the string "X-" or similar constructs. In practice, that convention causes more problems than it solves. Therefore, this document deprecates the convention for newly defined parameters with textual (as opposed to numerical) names in application protocols. This memo documents an Internet Best Current Practice.
RFC6647 - Email Greylisting: An Applicability Statement for SMTP
This document describes the art of email greylisting, the practice of providing temporarily degraded service to unknown email clients as an anti-abuse mechanism.
RFC6646 - DECoupled Application Data Enroute (DECADE) Problem Statement
Peer-to-peer (P2P) applications have become widely used on the Internet today and make up a large portion of the traffic in many networks. In P2P applications, one technique for reducing the transit and uplink P2P traffic is to introduce storage capabilities within the network. Traditional caches (e.g., P2P and Web caches) provide such storage, but they can be complex (e.g., P2P caches need to explicitly support individual P2P application protocols), and do not allow users to manage resource usage policies for content in the cache. This document discusses the introduction of in-network storage for P2P applications and shows the need for a standard protocol for accessing this storage. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6645 - IP Flow Information Accounting and Export Benchmarking Methodology
This document provides a methodology and framework for quantifying the performance impact of the monitoring of IP flows on a network device and the export of this information to a Collector. It identifies the rate at which the IP flows are created, expired, and successfully exported as a new performance metric in combination with traditional throughput. The metric is only applicable to the devices compliant with RFC 5470, "Architecture for IP Flow Information Export". The methodology quantifies the impact of the IP flow monitoring process on the network equipment. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6644 - Rebind Capability in DHCPv6 Reconfigure Messages
This document updates RFC 3315 (DHCPv6) to allow the Rebind message type to appear in the Reconfigure Message option of a Reconfigure message. It extends the Reconfigure message to allow a DHCPv6 server to cause a DHCPv6 client to send a Rebind message. The document also clarifies how a DHCPv6 client responds to a received Reconfigure message. [STANDARDS-TRACK]
RFC6643 - Translation of Structure of Management Information Version 2 (SMIv2) MIB Modules to YANG Modules
YANG is a data modeling language used to model configuration and state data manipulated by the Network Configuration Protocol (NETCONF), NETCONF remote procedure calls, and NETCONF notifications. The Structure of Management Information (SMIv2) defines fundamental data types, an object model, and the rules for writing and revising MIB modules for use with the Simple Network Management Protocol (SNMP). This document defines a translation of SMIv2 MIB modules into YANG modules, enabling read-only (config false) access to data objects defined in SMIv2 MIB modules via NETCONF. [STANDARDS-TRACK]
RFC6642 - RTP Control Protocol (RTCP) Extension for a Third-Party Loss Report
In a large RTP session using the RTP Control Protocol (RTCP) feedback mechanism defined in RFC 4585, a feedback target may experience transient overload if some event causes a large number of receivers to send feedback at once. This overload is usually avoided by ensuring that feedback reports are forwarded to all receivers, allowing them to avoid sending duplicate feedback reports. However, there are cases where it is not recommended to forward feedback reports, and this may allow feedback implosion. This memo discusses these cases and defines a new RTCP Third-Party Loss Report that can be used to inform receivers that the feedback target is aware of some loss event, allowing them to suppress feedback. Associated Session Description Protocol (SDP) signaling is also defined. [STANDARDS-TRACK]
RFC6641 - Using DNS SRV to Specify a Global File Namespace with NFS Version 4
The NFS version 4 (NFSv4) protocol provides a mechanism for a collection of NFS file servers to collaborate in providing an organization-wide file namespace. The DNS SRV Resource Record (RR) allows a simple way for an organization to publish the root of its file system namespace, even to clients that might not be intimately associated with such an organization. The DNS SRV RR can be used to join these organization-wide file namespaces together to allow construction of a global, uniform NFS file namespace. [STANDARDS-TRACK]
RFC6640 - IETF Meeting Attendees' Frequently Asked (Travel) Questions
This document attempts to provide a list of the frequently asked questions (FAQs) posed by IETF meeting attendees regarding travel logistics and local information. It is intended to assist those who are willing to provide local information, so that if they wish to pre-populate answers to some or all of these questions either in the IETF wiki or a meeting-specific site, they have a reasonably complete list of ideas to draw from. It is not meant as a list of required information that the host or Secretariat needs to provide; it merely serves as a guideline. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6639 - Multiprotocol Label Switching Transport Profile (MPLS-TP) MIB-Based Management Overview

The RFC Editor model described in this document divides the responsibilities for the RFC Series into three functions: the RFC Series Editor, the RFC Production Center, and the RFC Publisher. Internet Architecture Board (IAB) oversight via the RFC Series Oversight Committee (RSOC) is described, as is the relationship between the IETF Administrative Oversight Committee (IAOC) and the RSOC. This document reflects the experience gained with "RFC Editor Model (Version 1)", documented in RFC 5620, and obsoletes that document. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6633 - Deprecation of ICMP Source Quench Messages

RFC6632 - An Overview of the IETF Network Management Standards
This document gives an overview of the IETF network management standards and summarizes existing and ongoing development of IETF Standards Track network management protocols and data models. The document refers to other overview documents, where they exist and classifies the standards for easy orientation. The purpose of this document is, on the one hand, to help system developers and users to select appropriate standard management protocols and data models to address relevant management needs. On the other hand, the document can be used as an overview and guideline by other Standard Development Organizations or bodies planning to use IETF management technologies and data models. This document does not cover Operations, Administration, and Maintenance (OAM) technologies on the data-path, e.g., OAM of tunnels, MPLS Transport Profile (MPLS-TP) OAM, and pseudowire as well as the corresponding management models. This document is not an Internet Standards Track specification; it is published for informational purposes.
This document specifies an RTP payload format for the Forward Error Correction (FEC) repair data produced by the Raptor FEC Schemes.

RFC6681 - Raptor Forward Error Correction (FEC) Schemes for FECFRAME
This document describes Fully-Specified Forward Error Correction (FEC) Schemes for the Raptor and RaptorQ codes and their application to reliable delivery of media streams in the context of the FEC Framework. The Raptor and RaptorQ codes are systematic codes, where a number of repair symbols are generated from a set of source symbols and sent in one or more repair flows in addition to the source symbols that are sent to the receiver(s) within a source flow. The Raptor and RaptorQ codes offer close to optimal protection against arbitrary packet losses at a low computational complexity. Six FEC Schemes are defined: two for the protection of arbitrary packet flows, two that are optimized for small source blocks, and two for the protection of a single flow that already contains a sequence number. Repair data may be sent over arbitrary datagram transport (e.g., UDP) or using RTP. [STANDARDS-TRACK]

MPLS-TP is a set of functions and features selected from the extended MPLS toolset and applied in a consistent way to meet the needs and requirements of operators of packet transport networks.
RFC6669 - An Overview of the Operations, Administration, and Maintenance (OAM) Toolset for MPLS-Based Transport Networks
This document provides an overview of the Operations, Administration, and Maintenance (OAM) toolset for MPLS-based transport networks. The toolset consists of a comprehensive set of fault management and performance monitoring capabilities (operating in the data plane) that are appropriate for transport networks as required in RFC 5860 and support the network and services at different nested levels. This overview includes a brief recap of the MPLS Transport Profile (MPLS-TP) OAM requirements and functions and the generic mechanisms created in the MPLS data plane that allow the OAM packets to run in-band and share their fate with data packets. The protocol definitions for each of the MPLS-TP OAM tools are defined in separate documents (RFCs or Working Group documents), which are referenced by this document. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6668 - SHA-2 Data Integrity Verification for the Secure Shell (SSH) Transport Layer Protocol
This memo defines algorithm names and parameters for use in some of the SHA-2 family of secure hash algorithms for data integrity verification in the Secure Shell (SSH) protocol. It also updates RFC 4253 by specifying a new RECOMMENDED data integrity algorithm. [STANDARDS-TRACK]
RFC6667 - LDP 'Typed Wildcard' Forwarding Equivalence Class (FEC) for PWid and Generalized PWid FEC Elements
The "Typed Wildcard Forwarding Equivalence Class (FEC) Element" defines an extension to the Label Distribution Protocol (LDP) that can be used when requesting, withdrawing, or releasing all label bindings for a given FEC Element type is desired. However, a Typed Wildcard FEC Element must be individually defined for each FEC Element type. This specification defines the Typed Wildcard FEC Elements for the Pseudowire Identifier (PWid) (0x80) and Generalized PWid (0x81) FEC Element types. [STANDARDS-TRACK]
RFC6666 - A Discard Prefix for IPv6
Remote triggered black hole filtering describes a method of mitigating the effects of denial-of-service attacks by selectively discarding traffic based on source or destination address. Remote triggered black hole routing describes a method of selectively re- routing traffic into a sinkhole router (for further analysis) based on destination address. This document updates the "IPv6 Special Purpose Address Registry" by explaining why a unique IPv6 prefix should be formally assigned by IANA for the purpose of facilitating IPv6 remote triggered black hole filtering and routing. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6665 - SIP-Specific Event Notification
This document describes an extension to the Session Initiation Protocol (SIP) defined by RFC 3261. The purpose of this extension is to provide an extensible framework by which SIP nodes can request notification from remote nodes indicating that certain events have occurred.
RFC6664 - S/MIME Capabilities for Public Key Definitions
This document defines a set of Secure/Multipurpose Internet Mail Extensions (S/MIME) Capability types for ASN.1 encoding for the current set of public keys defined by the PKIX working group. This facilitates the ability for a requester to specify information on the public keys and signature algorithms to be used in responses. "Online Certificate Status Protocol Algorithm Agility" (RFC 6277) details an example of where this is used. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6663 - Requirements for Signaling of Pre-Congestion Information in a Diffserv Domain
Pre-Congestion Notification (PCN) is a means for protecting quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo describes the requirements for the signaling applied within the PCN-domain: (1) PCN-feedback-information is carried from the PCN-egress-node to the Decision Point; (2) the Decision Point may ask the PCN-ingress-node to measure, and report back, the rate of sent PCN-traffic between that PCN-ingress-node and PCN-egress-node. The Decision Point may be either collocated with the PCN-ingress-node or a centralized node (in the first case, (2) is not required). The signaling requirements pertain in particular to two edge behaviors, Controlled Load (CL) and Single Marking (SM). This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6662 - Pre-Congestion Notification (PCN) Boundary-Node Behavior for the Single Marking (SM) Mode of Operation
Pre-Congestion Notification (PCN) is a means for protecting the quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo is one of a series describing possible boundary-node behaviors for a PCN-domain. The behavior described here is that for a form of measurement-based load control using two PCN marking states: not- marked and excess-traffic-marked. This behavior is known informally as the Single Marking (SM) PCN-boundary-node behavior. This document defines an Experimental Protocol for the Internet community.
RFC6661 - Pre-Congestion Notification (PCN) Boundary-Node Behavior for the Controlled Load (CL) Mode of Operation
Pre-Congestion Notification (PCN) is a means for protecting the quality of service for inelastic traffic admitted to a Diffserv domain. The overall PCN architecture is described in RFC 5559. This memo is one of a series describing possible boundary-node behaviors for a PCN-domain. The behavior described here is that for a form of measurement-based load control using three PCN marking states: not- marked, threshold-marked, and excess-traffic-marked. This behavior is known informally as the Controlled Load (CL) PCN-boundary-node behavior. This document defines an Experimental Protocol for the Internet community.
RFC6660 - Encoding Three Pre-Congestion Notification (PCN) States in the IP Header Using a Single Diffserv Codepoint (DSCP)
The objective of Pre-Congestion Notification (PCN) is to protect the quality of service (QoS) of inelastic flows within a Diffserv domain. The overall rate of PCN-traffic is metered on every link in the PCN- domain, and PCN-packets are appropriately marked when certain configured rates are exceeded. Egress nodes pass information about these PCN-marks to Decision Points that then decide whether to admit or block new flow requests or to terminate some already admitted flows during serious pre-congestion.
RFC6659 - Considerations for Deploying the Rapid Acquisition of Multicast RTP Sessions (RAMS) Method
The Rapid Acquisition of Multicast RTP Sessions (RAMS) solution is a method based on RTP and the RTP Control Protocol (RTCP) that enables an RTP receiver to rapidly acquire and start consuming the RTP multicast data. Upon a request from the RTP receiver, an auxiliary unicast RTP retransmission session is set up between a retransmission server and the RTP receiver, over which the reference information about the new multicast stream the RTP receiver is about to join is transmitted at an accelerated rate. This often precedes, but may also accompany, the multicast stream itself. When there is only one multicast stream to be acquired, the RAMS solution works in a straightforward manner. However, when there are two or more multicast streams to be acquired from the same or different multicast RTP sessions, care should be taken to configure each RAMS session appropriately. This document provides example scenarios and discusses how the RAMS solution could be used in such scenarios. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6658 - Packet Pseudowire Encapsulation over an MPLS PSN
This document describes a pseudowire mechanism that is used to transport a packet service over an MPLS PSN in the case where the client Label Switching Router (LSR) and the server Provider Edge equipments are co-resident in the same equipment. This pseudowire mechanism may be used to carry all of the required layer 2 and layer 3 protocols between the pair of client LSRs. [STANDARDS-TRACK]

RFC6656 - Description of Cisco Systems' Subnet Allocation Option for DHCPv4
This memo documents a DHCPv4 option that currently exists and was previously privately defined for the operation and usage of the Cisco Systems' Subnet Allocation Option for DHCPv4. The option is passed between the DHCPv4 Client and the DHCPv4 Server to request dynamic allocation of a subnet, give specifications of the subnet(s) allocated, and report usage statistics. This memo documents the current usage of the option in agreement with RFC 3942, which declares that any preexisting usages of option numbers in the range 128-223 should be documented and that the working group will try to officially assign those numbers to those options. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6655 - AES-CCM Cipher Suites for Transport Layer Security (TLS)
This memo describes the use of the Advanced Encryption Standard (AES) in the Counter with Cipher Block Chaining - Message Authentication Code (CBC-MAC) Mode (CCM) of operation within Transport Layer Security (TLS) and Datagram TLS (DTLS) to provide confidentiality and data origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments. [STANDARDS-TRACK]
RFC6654 - Gateway-Initiated IPv6 Rapid Deployment on IPv4 Infrastructures (GI 6rd)
This document proposes an alternative IPv6 Rapid Deployment on IPv4 Infrastructures (6rd) deployment model to that of RFC 5969. The basic 6rd model allows IPv6 hosts to gain access to IPv6 networks across an IPv4 access network using 6-in-4 tunnels. 6rd requires support by a device (the 6rd customer edge, or 6rd-CE) on the customer site, which must also be assigned an IPv4 address. The alternative model described in this document initiates the 6-in-4 tunnels from an operator-owned Gateway collocated with the operator's IPv4 network edge rather than from customer equipment, and hence is termed "Gateway-initiated 6rd" (GI 6rd). The advantages of this approach are that it requires no modification to customer equipment and avoids assignment of IPv4 addresses to customer equipment. The latter point means less pressure on IPv4 addresses in a high-growth environment. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6653 - DHCPv6 Prefix Delegation in Long-Term Evolution (LTE) Networks
As interest in IPv6 deployment in cellular networks increases, several migration issues have been being raised; IPv6 prefix management is the issue addressed in this document. Based on the idea that DHCPv6 servers can manage prefixes, we use DHCPv6 Prefix Delegation to address such prefix management issues as an access router offloading delegation of prefixes and release tasks to a DHCPv6 server. The access router first requests a prefix for an incoming mobile node from the DHCPv6 server. The access router may next do stateless or stateful address allocation to the mobile node, e.g., with a Router Advertisement or using DHCP. We also describe prefix management using Authentication, Authorization, and Accounting (AAA) servers. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6652 - Sender Policy Framework (SPF) Authentication Failure Reporting Using the Abuse Reporting Format
This memo presents extensions to the Abuse Reporting Format (ARF) and Sender Policy Framework (SPF) specifications to allow for detailed reporting of message authentication failures in an on-demand fashion.

This document presents extensions to the DomainKeys Identified Mail (DKIM) specification to allow for detailed reporting of message authentication failures in an on-demand fashion. [STANDARDS-TRACK]
RFC6650 - Creation and Use of Email Feedback Reports: An Applicability Statement for the Abuse Reporting Format (ARF)
RFC 5965 defines an extensible, machine-readable format intended for mail operators to report feedback about received email to other parties. This applicability statement describes common methods for utilizing this format for reporting both abuse and authentication failure events. Mailbox Providers of any size, mail-sending entities, and end users can use these methods as a basis to create procedures that best suit them. Some related optional mechanisms are also discussed. [STANDARDS-TRACK]
RFC6649 - Deprecate DES, RC4-HMAC-EXP, and Other Weak Cryptographic Algorithms in Kerberos
The Kerberos 5 network authentication protocol, originally specified in RFC 1510, can use the Data Encryption Standard (DES) for encryption. Almost 30 years after first publishing DES, the National Institute of Standards and Technology (NIST) finally withdrew the standard in 2005, reflecting a long-established consensus that DES is insufficiently secure. By 2008, commercial hardware costing less than USD 15,000 could break DES keys in less than a day on average. DES is long past its sell-by date. Accordingly, this document updates RFC 1964, RFC 4120, RFC 4121, and RFC 4757 to deprecate the use of DES, RC4-HMAC-EXP, and other weak cryptographic algorithms in Kerberos. Because RFC 1510 (obsoleted by RFC 4120) supports only DES, this document recommends the reclassification of RFC 1510 as Historic. This memo documents an Internet Best Current Practice.
RFC6648 - Deprecating the "X-" Prefix and Similar Constructs in Application Protocols
Historically, designers and implementers of application protocols have often distinguished between standardized and unstandardized parameters by prefixing the names of unstandardized parameters with the string "X-" or similar constructs. In practice, that convention causes more problems than it solves. Therefore, this document deprecates the convention for newly defined parameters with textual (as opposed to numerical) names in application protocols. This memo documents an Internet Best Current Practice.
RFC6647 - Email Greylisting: An Applicability Statement for SMTP
This document describes the art of email greylisting, the practice of providing temporarily degraded service to unknown email clients as an anti-abuse mechanism.
RFC6646 - DECoupled Application Data Enroute (DECADE) Problem Statement
Peer-to-peer (P2P) applications have become widely used on the Internet today and make up a large portion of the traffic in many networks. In P2P applications, one technique for reducing the transit and uplink P2P traffic is to introduce storage capabilities within the network. Traditional caches (e.g., P2P and Web caches) provide such storage, but they can be complex (e.g., P2P caches need to explicitly support individual P2P application protocols), and do not allow users to manage resource usage policies for content in the cache. This document discusses the introduction of in-network storage for P2P applications and shows the need for a standard protocol for accessing this storage. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6645 - IP Flow Information Accounting and Export Benchmarking Methodology
This document provides a methodology and framework for quantifying the performance impact of the monitoring of IP flows on a network device and the export of this information to a Collector. It identifies the rate at which the IP flows are created, expired, and successfully exported as a new performance metric in combination with traditional throughput. The metric is only applicable to the devices compliant with RFC 5470, "Architecture for IP Flow Information Export". The methodology quantifies the impact of the IP flow monitoring process on the network equipment. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6644 - Rebind Capability in DHCPv6 Reconfigure Messages
This document updates RFC 3315 (DHCPv6) to allow the Rebind message type to appear in the Reconfigure Message option of a Reconfigure message. It extends the Reconfigure message to allow a DHCPv6 server to cause a DHCPv6 client to send a Rebind message. The document also clarifies how a DHCPv6 client responds to a received Reconfigure message. [STANDARDS-TRACK]
RFC6643 - Translation of Structure of Management Information Version 2 (SMIv2) MIB Modules to YANG Modules
YANG is a data modeling language used to model configuration and state data manipulated by the Network Configuration Protocol (NETCONF), NETCONF remote procedure calls, and NETCONF notifications. The Structure of Management Information (SMIv2) defines fundamental data types, an object model, and the rules for writing and revising MIB modules for use with the Simple Network Management Protocol (SNMP). This document defines a translation of SMIv2 MIB modules into YANG modules, enabling read-only (config false) access to data objects defined in SMIv2 MIB modules via NETCONF. [STANDARDS-TRACK]
RFC6642 - RTP Control Protocol (RTCP) Extension for a Third-Party Loss Report
In a large RTP session using the RTP Control Protocol (RTCP) feedback mechanism defined in RFC 4585, a feedback target may experience transient overload if some event causes a large number of receivers to send feedback at once. This overload is usually avoided by ensuring that feedback reports are forwarded to all receivers, allowing them to avoid sending duplicate feedback reports. However, there are cases where it is not recommended to forward feedback reports, and this may allow feedback implosion. This memo discusses these cases and defines a new RTCP Third-Party Loss Report that can be used to inform receivers that the feedback target is aware of some loss event, allowing them to suppress feedback. Associated Session Description Protocol (SDP) signaling is also defined. [STANDARDS-TRACK]
RFC6641 - Using DNS SRV to Specify a Global File Namespace with NFS Version 4
The NFS version 4 (NFSv4) protocol provides a mechanism for a collection of NFS file servers to collaborate in providing an organization-wide file namespace. The DNS SRV Resource Record (RR) allows a simple way for an organization to publish the root of its file system namespace, even to clients that might not be intimately associated with such an organization. The DNS SRV RR can be used to join these organization-wide file namespaces together to allow construction of a global, uniform NFS file namespace. [STANDARDS-TRACK]
