RFC Abstracts

RFC7063 - Survey Report on Protocol Independent Multicast - Sparse Mode (PIM-SM) Implementations and Deployments
This document provides supporting documentation to advance the IETF stream's Protocol Independent Multicast - Sparse Mode (PIM-SM) protocol from Proposed Standard to Internet Standard.
RFC7062 - Framework for GMPLS and PCE Control of G.709 Optical Transport Networks
This document provides a framework to allow the development of protocol extensions to support Generalized Multi-Protocol Label Switching (GMPLS) and Path Computation Element (PCE) control of Optical Transport Networks (OTNs) as specified in ITU-T Recommendation G.709 as published in 2012.
RFC7061 - eXtensible Access Control Markup Language (XACML) XML Media Type
This specification registers an XML-based media type for the eXtensible Access Control Markup Language (XACML).
RFC7060 - Using LDP Multipoint Extensions on Targeted LDP Sessions
Label Distribution Protocol (LDP) can be used to set up Point-to-Multipoint (P2MP) and Multipoint-to-Multipoint (MP2MP) Label Switched Paths. However, the specification for the Multipoint Extensions to LDP presupposes that the two endpoints of an LDP session are directly connected. The LDP base specification allows for the case where the two endpoints of an LDP session are not directly connected; such a session is known as a "Targeted LDP" session. This document provides the specification for using the LDP Multipoint Extensions over a Targeted LDP session.
RFC7059 - A Comparison of IPv6-over-IPv4 Tunnel Mechanisms
This document provides an overview of various ways to tunnel IPv6 packets over IPv4 networks. It covers mechanisms in current use, touches on several mechanisms that are now only of historic interest, and discusses some newer tunnel mechanisms that are not widely used at the time of publication. The goal of the document is helping people with an IPv6-in-IPv4 tunneling need to select the mechanisms that may apply to them.
RFC7058 - Media Control Channel Framework (CFW) Call Flow Examples
This document provides a list of typical Media Control Channel Framework call flows. It aims at being a simple guide to the use of the interface between Application Servers and MEDIACTRL-based Media Servers, as well as a base reference document for both implementors and protocol researchers.
RFC7057 - Update to the Extensible Authentication Protocol (EAP) Applicability Statement for Application Bridging for Federated Access Beyond Web (ABFAB)
This document updates the Extensible Authentication Protocol (EAP) applicability statement from RFC 3748 to reflect recent usage of the EAP protocol in the Application Bridging for Federated Access Beyond web (ABFAB) architecture.
RFC7056 - Name Attributes for the GSS-API Extensible Authentication Protocol (EAP) Mechanism
The naming extensions to the Generic Security Service Application Programming Interface (GSS-API) provide a mechanism for applications to discover authorization and personalization information associated with GSS-API names. The Extensible Authentication Protocol GSS-API mechanism allows an Authentication, Authorization, and Accounting (AAA) peer to provide authorization attributes alongside an authentication response. It also supplies mechanisms to process Security Assertion Markup Language (SAML) messages provided in the AAA response. This document describes how to use the Naming Extensions API to access that information.
RFC7055 - A GSS-API Mechanism for the Extensible Authentication Protocol
This document defines protocols, procedures, and conventions to be employed by peers implementing the Generic Security Service Application Program Interface (GSS-API) when using the Extensible Authentication Protocol mechanism. Through the GS2 family of mechanisms defined in RFC 5801, these protocols also define how Simple Authentication and Security Layer (SASL) applications use the Extensible Authentication Protocol.
RFC7054 - Addressing Requirements and Design Considerations for Per-Interface Maintenance Entity Group Intermediate Points (MIPs)
The framework for Operations, Administration and Maintenance (OAM) within the MPLS Transport Profile (MPLS-TP) describes how the Maintenance Entity Group Intermediate Points (MIPs) may be situated within network nodes at incoming and outgoing interfaces.
RFC7053 - SACK-IMMEDIATELY Extension for the Stream Control Transmission Protocol
This document updates RFC 4960 by defining a method for the sender of a DATA chunk to indicate that the corresponding Selective Acknowledgment (SACK) chunk should be sent back immediately and should not be delayed. It is done by specifying a bit in the DATA chunk header, called the (I)mmediate bit, which can get set by either the Stream Control Transmission Protocol (SCTP) implementation or the application using an SCTP stack. Since unknown flags in chunk headers are ignored by SCTP implementations, this extension does not introduce any interoperability problems.
RFC7052 - Locator/ID Separation Protocol (LISP) MIB
This document defines the MIB module that contains managed objects to support the monitoring devices of the Locator/ID Separation Protocol (LISP). These objects provide information useful for monitoring LISP devices, including determining basic LISP configuration information, LISP functional status, and operational counters and other statistics.
RFC7051 - Analysis of Solution Proposals for Hosts to Learn NAT64 Prefix
Hosts and applications may benefit from learning if an IPv6 address is synthesized and if NAT64 and DNS64 are present in a network. This document analyzes all proposed solutions (known at the time of writing) for communicating whether the synthesis is taking place, what address format was used, and what IPv6 prefix was used by the NAT64 and DNS64. These solutions enable both NAT64 avoidance and local IPv6 address synthesis. The document concludes by recommending the standardization of the approach based on heuristic discovery.
RFC7050 - Discovery of the IPv6 Prefix Used for IPv6 Address Synthesis
This document describes a method for detecting the presence of DNS64 and for learning the IPv6 prefix used for protocol translation on an access network. The method depends on the existence of a well-known IPv4-only fully qualified domain name "ipv4only.arpa.". The information learned enables nodes to perform local IPv6 address synthesis and to potentially avoid NAT64 on dual-stack and multi-interface deployments.
RFC7049 - Concise Binary Object Representation (CBOR)
The Concise Binary Object Representation (CBOR) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack.
RFC7048 - Neighbor Unreachability Detection Is Too Impatient
IPv6 Neighbor Discovery includes Neighbor Unreachability Detection. That function is very useful when a host has an alternative neighbor -- for instance, when there are multiple default routers -- since it allows the host to switch to the alternative neighbor in a short time. By default, this time is 3 seconds after the node starts probing. However, if there are no alternative neighbors, this timeout behavior is far too impatient. This document specifies relaxed rules for Neighbor Discovery retransmissions that allow an implementation to choose different timeout behavior based on whether or not there are alternative neighbors. This document updates RFC 4861.
RFC7047 - The Open vSwitch Database Management Protocol
Open vSwitch is an open-source software switch designed to be used as a vswitch (virtual switch) in virtualized server environments. A vswitch forwards traffic between different virtual machines (VMs) on the same physical host and also forwards traffic between VMs and the physical network. Open vSwitch is open to programmatic extension and control using OpenFlow and the OVSDB (Open vSwitch Database) management protocol. This document defines the OVSDB management protocol. The Open vSwitch project includes open-source OVSDB client and server implementations.
RFC7046 - A Common API for Transparent Hybrid Multicast
Group communication services exist in a large variety of flavors and technical implementations at different protocol layers. Multicast data distribution is most efficiently performed on the lowest available layer, but a heterogeneous deployment status of multicast technologies throughout the Internet requires an adaptive service binding at runtime. Today, it is difficult to write an application that runs everywhere and at the same time makes use of the most efficient multicast service available in the network. Facing robustness requirements, developers are frequently forced to use a stable upper-layer protocol provided by the application itself. This document describes a common multicast API that is suitable for transparent communication in underlay and overlay and that grants access to the different flavors of multicast. It proposes an abstract naming scheme that uses multicast URIs, and it discusses mapping mechanisms between different namespaces and distribution technologies. Additionally, this document describes the application of this API for building gateways that interconnect current Multicast Domains throughout the Internet. It reports on an implementation of the programming Interface, including service middleware. This document is a product of the Scalable Adaptive Multicast (SAM) Research Group.
RFC7045 - Transmission and Processing of IPv6 Extension Headers
Various IPv6 extension headers have been standardised since the IPv6 standard was first published. This document updates RFC 2460 to clarify how intermediate nodes should deal with such extension headers and with any that are defined in the future. It also specifies how extension headers should be registered by IANA, with a corresponding minor update to RFC 2780.
RFC7044 - An Extension to the Session Initiation Protocol (SIP) for Request History Information
This document defines a standard mechanism for capturing the history information associated with a Session Initiation Protocol (SIP) request. This capability enables many enhanced services by providing the information as to how and why a SIP request arrives at a specific application or user. This document defines an optional SIP header field, History-Info, for capturing the history information in requests. The document also defines SIP header field parameters for the History-Info and Contact header fields to tag the method by which the target of a request is determined. In addition, this specification defines a value for the Privacy header field that directs the anonymization of values in the History-Info header field. This document obsoletes RFC 4244.
RFC7043 - Resource Records for EUI-48 and EUI-64 Addresses in the DNS
48-bit Extended Unique Identifier (EUI-48) and 64-bit Extended Unique Identifier (EUI-64) are address formats specified by the IEEE for use in various layer-2 networks, e.g., Ethernet.
RFC7042 - IANA Considerations and IETF Protocol and Documentation Usage for IEEE 802 Parameters
Some IETF protocols make use of Ethernet frame formats and IEEE 802 parameters. This document discusses several uses of such parameters in IETF protocols, specifies IANA considerations for assignment of points under the IANA OUI (Organizationally Unique Identifier), and provides some values for use in documentation. This document obsoletes RFC 5342.
RFC7041 - Extensions to the Virtual Private LAN Service (VPLS) Provider Edge (PE) Model for Provider Backbone Bridging
The IEEE 802.1 Provider Backbone Bridges (PBBs) specification defines an architecture and bridge protocols for interconnection of multiple Provider Bridged Networks (PBNs). Provider backbone bridging was defined by IEEE as a connectionless technology based on multipoint VLAN tunnels. PBB can be used to attain better scalability than Provider Bridges (PBs) in terms of the number of customer Media Access Control addresses and the number of service instances that can be supported.
RFC7040 - Public IPv4-over-IPv6 Access Network
This document describes a mechanism called Public 4over6, which is designed to provide IPv4 Internet connectivity over an IPv6 access network using global IPv4 addresses. Public 4over6 was developed in the IETF and is in use in some existing deployments but is not recommended for new deployments. Future deployments of similar scenarios should use Lightweight 4over6. Public 4over6 follows the Hub and Spoke softwire model and uses an IPv4-in-IPv6 tunnel to forward IPv4 packets over an IPv6 access network. The bidirectionality of the IPv4 communication is achieved by explicitly allocating global non-shared IPv4 addresses to end users and by maintaining IPv4-IPv6 address binding on the border relay. Public 4over6 aims to provide uninterrupted IPv4 services to users, like Internet Content Providers (ICPs), etc., while an operator makes the access network transition to an IPv6-only access network.
RFC7039 - Source Address Validation Improvement (SAVI) Framework
Source Address Validation Improvement (SAVI) methods were developed to prevent nodes attached to the same IP link from spoofing each other's IP addresses, so as to complement ingress filtering with finer-grained, standardized IP source address validation. This document is a framework document that describes and motivates the design of the SAVI methods. Particular SAVI methods are described in other documents.
RFC7038 - Use of OSPF-MDR in Single-Hop Broadcast Networks
RFC 5614 (OSPF-MDR) extends OSPF to support mobile ad hoc networks (MANETs) by specifying its operation on the new OSPF interface of type MANET. This document describes the use of OSPF-MDR (MANET Designated Router) in a single-hop broadcast network, which is a special case of a MANET in which each router is a (one-hop) neighbor of each other router. Unlike an OSPF broadcast interface, such an interface can have a different cost associated with each neighbor. The document includes configuration recommendations and simplified mechanisms that can be used in single-hop broadcast networks.
RFC7037 - RADIUS Option for the DHCPv6 Relay Agent
The DHCPv6 RADIUS option provides a mechanism to exchange authorization and identification information between the DHCPv6 relay agent and DHCPv6 server. This architecture assumes that the Network Access Server (NAS) acts as both a DHCPv6 relay agent and RADIUS client. When receiving messages from the DHCPv6 clients, the NAS consults the RADIUS server and adds the RADIUS response when forwarding the DHCPv6 client's messages to the DHCPv6 server. The DHCPv6 server then uses that additional information to generate an appropriate response to the DHCPv6 client's requests.
RFC7036 - Object Identifier Registry for the Long-Term Archive and Notary Services (LTANS) Working Group
When the Long-Term Archive and Notary Services (LTANS) working group was chartered, an object identifier arc was set aside for use by that working group. This document describes the object identifiers that were assigned, and it establishes IANA allocation policies for any future assignments within that arc.
RFC7035 - Relative Location Representation
This document defines an extension to the Presence Information Data Format Location Object (PIDF-LO) (RFC 4119) for the expression of location information that is defined relative to a reference point. The reference point may be expressed as a geodetic or civic location, and the relative offset may be one of several shapes. An alternative binary representation is described.
RFC7034 - HTTP Header Field X-Frame-Options
To improve the protection of web applications against clickjacking, this document describes the X-Frame-Options HTTP header field, which declares a policy, communicated from the server to the client browser, regarding whether the browser may display the transmitted content in frames that are part of other web pages.
RFC7033 - WebFinger
This specification defines the WebFinger protocol, which can be used to discover information about people or other entities on the Internet using standard HTTP methods. WebFinger discovers information for a URI that might not be usable as a locator otherwise, such as account or email URIs.
RFC7032 - LDP Downstream-on-Demand in Seamless MPLS
Seamless MPLS design enables a single IP/MPLS network to scale over core, metro, and access parts of a large packet network infrastructure using standardized IP/MPLS protocols. One of the key goals of Seamless MPLS is to meet requirements specific to access networks including high number of devices, device position in network topology, and compute and memory constraints that limit the amount of state access devices can hold. This can be achieved with LDP Downstream-on-Demand (DoD) label advertisement. This document describes LDP DoD use cases and lists required LDP DoD procedures in the context of Seamless MPLS design.
RFC7031 - DHCPv6 Failover Requirements
The DHCPv6 protocol, defined in RFC 3315, allows for multiple servers to operate on a single network; however, it does not define any way the servers could share information about currently active clients and their leases. Some sites are interested in running multiple servers in such a way as to provide increased availability in case of server failure. In order for this to work reliably, the cooperating primary and secondary servers must maintain a consistent database of the lease information. RFC 3315 allows for, but does not define, any redundancy or failover mechanisms. This document outlines requirements for DHCPv6 failover, enumerates related problems, and discusses the proposed scope of work to be conducted. This document does not define a DHCPv6 failover protocol.
RFC7030 - Enrollment over Secure Transport
This document profiles certificate enrollment for clients using Certificate Management over CMS (CMC) messages over a secure transport. This profile, called Enrollment over Secure Transport (EST), describes a simple, yet functional, certificate management protocol targeting Public Key Infrastructure (PKI) clients that need to acquire client certificates and associated Certification Authority (CA) certificates. It also supports client-generated public/private key pairs as well as key pairs generated by the CA.
RFC7029 - Extensible Authentication Protocol (EAP) Mutual Cryptographic Binding
As the Extensible Authentication Protocol (EAP) evolves, EAP peers rely increasingly on information received from the EAP server. EAP extensions such as channel binding or network posture information are often carried in tunnel methods; peers are likely to rely on this information. Cryptographic binding is a facility described in RFC 3748 that protects tunnel methods against man-in-the-middle attacks. However, cryptographic binding focuses on protecting the server rather than the peer. This memo explores attacks possible when the peer is not protected from man-in-the-middle attacks and recommends cryptographic binding based on an Extended Master Session Key, a new form of cryptographic binding that protects both peer and server along with other mitigations.
RFC7028 - Multicast Mobility Routing Optimizations for Proxy Mobile IPv6
This document proposes some experimental enhancements to the base solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6) domain. These enhancements include the use of a multicast tree mobility anchor as the topological anchor point for multicast traffic, as well as a direct routing option where the Mobile Access Gateway can provide access to multicast content in the local network. The goal of these enhancements is to provide benefits such as reducing multicast traffic replication and supporting different PMIPv6 deployment scenarios.
RFC7027 - Elliptic Curve Cryptography (ECC) Brainpool Curves for Transport Layer Security (TLS)
This document specifies the use of several Elliptic Curve Cryptography (ECC) Brainpool curves for authentication and key exchange in the Transport Layer Security (TLS) protocol.
RFC7026 - Retiring TLVs from the Associated Channel Header of the MPLS Generic Associated Channel
The MPLS Generic Associated Channel (G-ACh) is a generalization of the applicability of the pseudowire (PW) Associated Channel Header (ACH). RFC 5586 defines the concept of TLV constructs that can be carried in messages on the G-ACh by placing them in the ACH between the fixed header fields and the G-ACh message. These TLVs are called ACH TLVs
RFC7025 - Requirements for GMPLS Applications of PCE
The initial effort of the PCE (Path Computation Element) WG focused mainly on MPLS. As a next step, this document describes functional requirements for GMPLS applications of PCE.
RFC7024 - Virtual Hub-and-Spoke in BGP/MPLS VPNs
With BGP/MPLS Virtual Private Networks (VPNs), providing any-to-any connectivity among sites of a given VPN would require each Provider Edge (PE) router connected to one or more of these sites to hold all the routes of that VPN. The approach described in this document allows the VPN service provider to reduce the number of PE routers that have to maintain all these routes by requiring only a subset of these routers to maintain all these routes.
RFC7023 - MPLS and Ethernet Operations, Administration, and Maintenance (OAM) Interworking
This document specifies the mapping of defect states between Ethernet Attachment Circuits (ACs) and associated Ethernet pseudowires (PWs) connected in accordance with the Pseudowire Emulation Edge-to-Edge (PWE3) architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects.
RFC7022 - Guidelines for Choosing RTP Control Protocol (RTCP) Canonical Names (CNAMEs)
The RTP Control Protocol (RTCP) Canonical Name (CNAME) is a persistent transport-level identifier for an RTP endpoint. While the Synchronization Source (SSRC) identifier of an RTP endpoint may change if a collision is detected or when the RTP application is restarted, its RTCP CNAME is meant to stay unchanged, so that RTP endpoints can be uniquely identified and associated with their RTP media streams.
RFC7021 - Assessing the Impact of Carrier-Grade NAT on Network Applications
NAT444 is an IPv4 extension technology being considered by Service Providers as a means to continue offering IPv4 service to customers while transitioning to IPv6. This technology adds an extra Carrier- Grade NAT (CGN) in the Service Provider network, often resulting in two NATs. CableLabs, Time Warner Cable, and Rogers Communications independently tested the impacts of NAT444 on many popular Internet services using a variety of test scenarios, network topologies, and vendor equipment. This document identifies areas where adding a second layer of NAT disrupts the communication channel for common Internet applications. This document was updated to include the Dual-Stack Lite (DS-Lite) impacts also.
RFC7020 - The Internet Numbers Registry System
This document provides information about the current Internet Numbers Registry System used in the distribution of globally unique Internet Protocol (IP) address space and autonomous system (AS) numbers.
RFC7019 - Application-Layer Multicast Extensions to REsource LOcation And Discovery (RELOAD)
We define a REsource LOcation And Discovery (RELOAD) Usage for Application-Layer Multicast (ALM) as well as a mapping to the RELOAD experimental message type to support ALM. The ALM Usage is intended to support a variety of ALM control algorithms in an overlay-independent way. Two example algorithms are defined, based on Scribe and P2PCast.
RFC7018 - Auto-Discovery VPN Problem Statement and Requirements
This document describes the problem of enabling a large number of systems to communicate directly using IPsec to protect the traffic between them. It then expands on the requirements for such a solution.
RFC7017 - IMAP Access to IETF Email List Archives
The IETF makes heavy use of email lists to conduct its work. This often involves accessing the archived history of those email lists. Participants would like to have the ability to browse and search those archives using standard IMAP clients. This memo captures the requirements for providing a service that would allow such browsing and searching, and it is intended as input to a later activity for the design and development of such a service.
RFC7016 - Adobe's Secure Real-Time Media Flow Protocol
This memo describes Adobe's Secure Real-Time Media Flow Protocol (RTMFP), an endpoint-to-endpoint communication protocol designed to securely transport parallel flows of real-time video, audio, and data messages, as well as bulk data, over IP networks. RTMFP has features that make it effective for peer-to-peer (P2P) as well as client-server communications, even when Network Address Translators (NATs) are used.
RFC7015 - Flow Aggregation for the IP Flow Information Export (IPFIX) Protocol
This document provides a common implementation-independent basis for the interoperable application of the IP Flow Information Export (IPFIX) protocol to the handling of Aggregated Flows, which are IPFIX Flows representing packets from multiple Original Flows sharing some set of common properties. It does this through a detailed terminology and a descriptive Intermediate Aggregation Process architecture, including a specification of methods for Original Flow counting and counter distribution across intervals.
RFC7014 - Flow Selection Techniques
The Intermediate Flow Selection Process is the process of selecting a subset of Flows from all observed Flows. The Intermediate Flow Selection Process may be located at an IP Flow Information Export (IPFIX) Exporter or Collector, or within an IPFIX Mediator. It reduces the effort of post-processing Flow data and transferring Flow Records. This document describes motivations for using the Intermediate Flow Selection process and presents Intermediate Flow Selection techniques. It provides an information model for configuring Intermediate Flow Selection Process techniques and discusses what information about an Intermediate Flow Selection Process should be exported.
