RFC6414 - Benchmarking Terminology for Protection Performance
This document provides common terminology and metrics for benchmarking the performance of sub-IP layer protection mechanisms. The performance benchmarks are measured at the IP layer; protection may be provided at the sub-IP layer. The benchmarks and terminology can be applied in methodology documents for different sub-IP layer protection mechanisms such as Automatic Protection Switching (APS), Virtual Router Redundancy Protocol (VRRP), Stateful High Availability (HA), and Multiprotocol Label Switching Fast Reroute (MPLS-FRR). This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6413 - Benchmarking Methodology for Link-State IGP Data-Plane Route Convergence
This document describes the methodology for benchmarking Link-State Interior Gateway Protocol (IGP) Route Convergence. The methodology is to be used for benchmarking IGP convergence time through externally observable (black-box) data-plane measurements. The methodology can be applied to any link-state IGP, such as IS-IS and OSPF. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6412 - Terminology for Benchmarking Link-State IGP Data-Plane Route Convergence
This document describes the terminology for benchmarking link-state Interior Gateway Protocol (IGP) route convergence. The terminology is to be used for benchmarking IGP convergence time through externally observable (black-box) data-plane measurements. The terminology can be applied to any link-state IGP, such as IS-IS and OSPF. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6411 - Applicability of Keying Methods for RSVP Security
The Resource reSerVation Protocol (RSVP) allows hop-by-hop integrity protection of RSVP neighbors. This requires messages to be cryptographically protected using a shared secret between participating nodes. This document compares group keying for RSVP with per-neighbor or per-interface keying, and discusses the associated key provisioning methods as well as applicability and limitations of these approaches. This document also discusses applicability of encrypting RSVP messages. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6410 - Reducing the Standards Track to Two Maturity Levels
This document updates the Internet Engineering Task Force (IETF) Standards Process defined in RFC 2026. Primarily, it reduces the Standards Process from three Standards Track maturity levels to two. This memo documents an Internet Best Current Practice.
RFC6409 - Message Submission for Mail
This memo splits message submission from message relay, allowing each service to operate according to its own rules (for security, policy, etc.), and specifies what actions are to be taken by a submission server.
RFC6408 - Diameter Straightforward-Naming Authority Pointer (S-NAPTR) Usage
The Diameter base protocol specifies mechanisms whereby a given realm may advertise Diameter nodes and the supported transport protocol. However, these mechanisms do not reveal the Diameter applications that each node supports. A peer outside the realm would have to perform a Diameter capability exchange with every node until it discovers one that supports the required application. This document updates RFC 3588, "Diameter Base Protocol", and describes an improvement using an extended format for the Straightforward-Naming Authority Pointer (S-NAPTR) application service tag that allows for discovery of the supported applications without doing Diameter capability exchange beforehand. [STANDARDS-TRACK]
RFC6407 - The Group Domain of Interpretation
This document describes the Group Domain of Interpretation (GDOI) protocol specified in RFC 3547. The GDOI provides group key management to support secure group communications according to the architecture specified in RFC 4046. The GDOI manages group security associations, which are used by IPsec and potentially other data security protocols. This document replaces RFC 3547. [STANDARDS-TRACK]
RFC6406 - Session PEERing for Multimedia INTerconnect (SPEERMINT) Architecture
This document defines a peering architecture for the Session Initiation Protocol (SIP) and its functional components and interfaces. It also describes the components and the steps necessary to establish a session between two SIP Service Provider (SSP) peering domains. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6405 - Voice over IP (VoIP) SIP Peering Use Cases
This document depicts many common Voice over IP (VoIP) use cases for Session Initiation Protocol (SIP) peering. These use cases are categorized into static and on-demand, and then further sub- categorized into direct and indirect. These use cases are not an exhaustive set, but rather the most common use cases deployed today. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6404 - Session PEERing for Multimedia INTerconnect (SPEERMINT) Security Threats and Suggested Countermeasures
The Session PEERing for Multimedia INTerconnect (SPEERMINT) working group (WG) provides a peering framework that leverages the building blocks of existing IETF-defined protocols such as SIP and ENUM for the interconnection between SIP Service Providers (SSPs). The objective of this document is to identify and enumerate SPEERMINT- specific threat vectors and to give guidance for implementers on selecting appropriate countermeasures. Security requirements for SPEERMINT that have been derived from the threats detailed in this document can be found in RFC 6271; this document provides concrete countermeasures to meet those SPEERMINT security requirements. In this document, the different security threats related to SPEERMINT are classified into threats to the Lookup Function (LUF), the Location Routing Function (LRF), the Signaling Function (SF), and the Media Function (MF) of a specific SIP Service Provider. Various instances of the threats are briefly introduced inside the classification. Finally, existing security solutions for SIP and RTP/RTCP (Real-time Transport Control Protocol) are presented to describe countermeasures currently available for such threats. Each SSP may have connections to one or more remote SSPs through peering or transit contracts. A potentially compromised remote SSP that attacks other SSPs is out of the scope of this document; this document focuses on attacks on an SSP from outside the trust domain such an SSP may have with other SSPs. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6403 - Suite B Profile of Certificate Management over CMS
The United States government has published guidelines for "NSA Suite\0B Cryptography", which defines cryptographic algorithm policy for national security applications. This document specifies a profile of the Certificate Management over CMS (CMC) protocol for managing Suite B X.509 public key certificates. This profile is a refinement of RFCs 5272, 5273, and 5274. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6402 - Certificate Management over CMS (CMC) Updates
This document contains a set of updates to the base syntax for CMC, a Certificate Management protocol using the Cryptographic Message Syntax (CMS). This document updates RFC 5272, RFC 5273, and RFC 5274.
RFC6401 - RSVP Extensions for Admission Priority
Some applications require the ability to provide an elevated probability of session establishment to specific sessions in times of network congestion. When supported over the Internet Protocol suite, this may be facilitated through a network-layer admission control solution that supports prioritized access to resources (e.g., bandwidth). These resources may be explicitly set aside for prioritized sessions, or may be shared with other sessions. This document specifies extensions to the Resource reSerVation Protocol (RSVP) that can be used to support such an admission priority capability at the network layer.
RFC6398 - IP Router Alert Considerations and Usage
The IP Router Alert Option is an IP option that alerts transit routers to more closely examine the contents of an IP packet. The Resource reSerVation Protocol (RSVP), Pragmatic General Multicast (PGM), the Internet Group Management Protocol (IGMP), Multicast Listener Discovery (MLD), Multicast Router Discovery (MRD), and General Internet Signaling Transport (GIST) are some of the protocols that make use of the IP Router Alert Option. This document discusses security aspects and usage guidelines around the use of the current IP Router Alert Option, thereby updating RFC 2113 and RFC 2711. Specifically, it provides recommendations against using the Router Alert in the end-to-end open Internet and identifies controlled environments where protocols depending on Router Alert can be used safely. It also provides recommendations about protection approaches for service providers. Finally, it provides brief guidelines for Router Alert implementation on routers. This memo documents an Internet Best Current Practice.
RFC6397 - Multi-Threaded Routing Toolkit (MRT) Border Gateway Protocol (BGP) Routing Information Export Format with Geo-Location Extensions
This document updates the Multi-threaded Routing Toolkit (MRT) export format for Border Gateway Protocol (BGP) routing information by extending it to include optional terrestrial coordinates of a BGP collector and its BGP peers. [STANDARDS-TRACK]
RFC6396 - Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format
This document describes the MRT format for routing information export. This format was developed in concert with the Multi-threaded Routing Toolkit (MRT) from whence the format takes it name. The format can be used to export routing protocol messages, state changes, and routing information base contents. [STANDARDS-TRACK]
RFC6395 - An Interface Identifier (ID) Hello Option for PIM
This document defines a new PIM Hello option to advertise an Interface Identifier that can be used by PIM protocols to uniquely identify an interface of a neighboring router. [STANDARDS-TRACK]
RFC6394 - Use Cases and Requirements for DNS-Based Authentication of Named Entities (DANE)
Many current applications use the certificate-based authentication features in Transport Layer Security (TLS) to allow clients to verify that a connected server properly represents a desired domain name. Typically, this authentication has been based on PKIX certificate chains rooted in well-known certificate authorities (CAs), but additional information can be provided via the DNS itself. This document describes a set of use cases in which the DNS and DNS Security Extensions (DNSSEC) could be used to make assertions that support the TLS authentication process. The main focus of this document is TLS server authentication, but it also covers TLS client authentication for applications where TLS clients are identified by domain names. [STANDARDS-TRACK]
RFC6393 - Moving RFC 4693 to Historic
This document moves RFC 4693 to Historic status. It also obsoletes RFC 4693. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6392 - A Survey of In-Network Storage Systems
This document surveys deployed and experimental in-network storage systems and describes their applicability for the DECADE (DECoupled Application Data Enroute) architecture. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6391 - Flow-Aware Transport of Pseudowires over an MPLS Packet Switched Network
Where the payload of a pseudowire comprises a number of distinct flows, it can be desirable to carry those flows over the Equal Cost Multiple Paths (ECMPs) that exist in the packet switched network. Most forwarding engines are able to generate a hash of the MPLS label stack and use this mechanism to balance MPLS flows over ECMPs.
RFC6390 - Guidelines for Considering New Performance Metric Development
This document describes a framework and a process for developing Performance Metrics of protocols and applications transported over IETF-specified protocols. These metrics can be used to characterize traffic on live networks and services. This memo documents an Internet Best Current Practice.
RFC6389 - MPLS Upstream Label Assignment for LDP
This document describes procedures for distributing upstream-assigned labels for the Label Distribution Protocol (LDP). It also describes how these procedures can be used for avoiding branch Label Switching Router (LSR) traffic replication on a LAN for LDP point-to-multipoint (P2MP) Label Switched Paths (LSPs). [STANDARDS-TRACK]
RFC6388 - Label Distribution Protocol Extensions for Point-to-Multipoint and Multipoint-to-Multipoint Label Switched Paths
This document describes extensions to the Label Distribution Protocol (LDP) for the setup of point-to-multipoint (P2MP) and multipoint-to-multipoint (MP2MP) Label Switched Paths (LSPs) in MPLS networks. These extensions are also referred to as multipoint LDP. Multipoint LDP constructs the P2MP or MP2MP LSPs without interacting with or relying upon any other multicast tree construction protocol. Protocol elements and procedures for this solution are described for building such LSPs in a receiver-initiated manner. There can be various applications for multipoint LSPs, for example IP multicast or support for multicast in BGP/MPLS Layer 3 Virtual Private Networks (L3VPNs). Specification of how such applications can use an LDP signaled multipoint LSP is outside the scope of this document. [STANDARDS-TRACK]
RFC6387 - GMPLS Asymmetric Bandwidth Bidirectional Label Switched Paths (LSPs)
This document defines a method for the support of GMPLS asymmetric bandwidth bidirectional Label Switched Paths (LSPs). The approach presented is applicable to any switching technology and builds on the original Resource Reservation Protocol (RSVP) model for the transport of traffic-related parameters. This document moves the experiment documented in RFC 5467 to the standards track and obsoletes RFC 5467. [STANDARDS-TRACK]
RFC6386 - VP8 Data Format and Decoding Guide
This document describes the VP8 compressed video data format, together with a discussion of the decoding procedure for the format. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6385 - General Area Review Team (Gen-ART) Experiences
The General Area Review Team (Gen-ART) has been doing reviews of Internet-Drafts (I-Ds) since 2004. This document discusses the experience and the lessons learned over the past 7 years of this process. The review team initially reviewed the I-Ds before each of the IESG telechats. Since late 2005, review team members have been assigned to review I-Ds during IETF Last Call, unless no IETF Last Call is necessary for the I-D. The same reviewer then reviews any updates when the I-D is placed on an IESG telechat agenda. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6384 - An FTP Application Layer Gateway (ALG) for IPv6-to-IPv4 Translation
The File Transfer Protocol (FTP) has a very long history, and despite the fact that today other options exist to perform file transfers, FTP is still in common use. As such, in situations where some client computers only have IPv6 connectivity while many servers are still IPv4-only and IPv6-to-IPv4 translators are used to bridge that gap, it is important that FTP is made to work through these translators to the best possible extent.
RFC6383 - Advice on When It Is Safe to Start Sending Data on Label Switched Paths Established Using RSVP-TE
The Resource Reservation Protocol (RSVP) has been extended to support Traffic Engineering (TE) in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. The protocol enables signaling exchanges to establish Label Switched Paths (LSPs) that traverse nodes and link to provide end-to-end data paths. Each node is programmed with "cross-connect" information as the signaling messages are processed. The cross-connection information instructs the node how to forward data that it receives.
RFC6382 - Unique Origin Autonomous System Numbers (ASNs) per Node for Globally Anycasted Services
This document makes recommendations regarding the use of unique origin autonomous system numbers (ASNs) per node for globally anycasted critical infrastructure services in order to provide routing system discriminators for a given anycasted prefix. Network management and monitoring techniques, or other operational mechanisms, may employ this new discriminator in whatever manner best accommodates their operating environment. This memo documents an Internet Best Current Practice.
RFC6381 - The 'Codecs' and 'Profiles' Parameters for "Bucket" Media Types
Several MIME type/subtype combinations exist that can contain different media formats. A receiving agent thus needs to examine the details of such media content to determine if the specific elements can be rendered given an available set of codecs. Especially when the end system has limited resources, or the connection to the end system has limited bandwidth, it is helpful to know from the Content- Type alone if the content can be rendered.
RFC6380 - Suite B Profile for Internet Protocol Security (IPsec)
The United States Government has published guidelines for "NSA Suite B Cryptography" dated July, 2005, which defines cryptographic algorithm policy for national security applications. This document specifies the conventions for using Suite B cryptography in IP Security (IPsec).
RFC6379 - Suite B Cryptographic Suites for IPsec
This document proposes four cryptographic user interface suites ("UI suites") for IP Security (IPsec), similar to the two suites specified in RFC 4308. The four new suites provide compatibility with the United States National Security Agency's Suite B specifications. This document obsoletes RFC 4869, which presented earlier versions of these suites. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6378 - MPLS Transport Profile (MPLS-TP) Linear Protection
This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunications Union Telecommunications Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge (PWE3) architectures to support the capabilities and functionalities of a packet transport network as defined by the ITU-T.
RFC6377 - DomainKeys Identified Mail (DKIM) and Mailing Lists
DomainKeys Identified Mail (DKIM) allows an ADministrative Management Domain (ADMD) to assume some responsibility for a message. Based on deployment experience with DKIM, this document provides guidance for the use of DKIM with scenarios that include Mailing List Managers (MLMs). This memo documents an Internet Best Current Practice.
RFC6376 - DomainKeys Identified Mail (DKIM) Signatures
DomainKeys Identified Mail (DKIM) permits a person, role, or organization that owns the signing domain to claim some responsibility for a message by associating the domain with the message. This can be an author's organization, an operational relay, or one of their agents. DKIM separates the question of the identity of the Signer of the message from the purported author of the message. Assertion of responsibility is validated through a cryptographic signature and by querying the Signer's domain directly to retrieve the appropriate public key. Message transit from author to recipient is through relays that typically make no substantive change to the message content and thus preserve the DKIM signature.
RFC6375 - A Packet Loss and Delay Measurement Profile for MPLS-Based Transport Networks
Procedures and protocol mechanisms to enable efficient and accurate measurement of packet loss, delay, and throughput in MPLS networks are defined in RFC 6374.
RFC6374 - Packet Loss and Delay Measurement for MPLS Networks
Many service provider service level agreements (SLAs) depend on the ability to measure and monitor performance metrics for packet loss and one-way and two-way delay, as well as related metrics such as delay variation and channel throughput. This measurement capability also provides operators with greater visibility into the performance characteristics of their networks, thereby facilitating planning, troubleshooting, and network performance evaluation. This document specifies protocol mechanisms to enable the efficient and accurate measurement of these performance metrics in MPLS networks. [STANDARDS-TRACK]
RFC6373 - MPLS Transport Profile (MPLS-TP) Control Plane Framework
The MPLS Transport Profile (MPLS-TP) supports static provisioning of transport paths via a Network Management System (NMS) and dynamic provisioning of transport paths via a control plane. This document provides the framework for MPLS-TP dynamic provisioning and covers control-plane addressing, routing, path computation, signaling, traffic engineering, and path recovery. MPLS-TP uses GMPLS as the control plane for MPLS-TP Label Switched Paths (LSPs). MPLS-TP also uses the pseudowire (PW) control plane for pseudowires. Management-plane functions are out of scope of this document.
RFC6372 - MPLS Transport Profile (MPLS-TP) Survivability Framework
Network survivability is the ability of a network to recover traffic delivery following failure or degradation of network resources. Survivability is critical for the delivery of guaranteed network services, such as those subject to strict Service Level Agreements (SLAs) that place maximum bounds on the length of time that services may be degraded or unavailable.
RFC6371 - Operations, Administration, and Maintenance Framework for MPLS-Based Transport Networks
The Transport Profile of Multiprotocol Label Switching (MPLS-TP) is a packet-based transport technology based on the MPLS Traffic Engineering (MPLS-TE) and pseudowire (PW) data-plane architectures.
RFC6370 - MPLS Transport Profile (MPLS-TP) Identifiers
This document specifies an initial set of identifiers to be used in the Transport Profile of Multiprotocol Label Switching (MPLS-TP). The MPLS-TP requirements (RFC 5654) require that the elements and objects in an MPLS-TP environment are able to be configured and managed without a control plane. In such an environment, many conventions for defining identifiers are possible. This document defines identifiers for MPLS-TP management and Operations, Administration, and Maintenance (OAM) functions compatible with IP/ MPLS conventions.
RFC6369 - Forwarding and Control Element Separation (ForCES) Implementation Experience
The Forwarding and Control Element Separation (ForCES) protocol defines a standard communication and control mechanism through which a Control Element (CE) can control the behavior of a Forwarding Element (FE). This document captures the experience of implementing the ForCES protocol and model. Its aim is to help others by providing examples and possible strategies for implementing the ForCES protocol. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6368 - Internal BGP as the Provider/Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs)
This document defines protocol extensions and procedures for BGP Provider/Customer Edge router iteration in BGP/MPLS IP VPNs. These extensions and procedures have the objective of making the usage of the BGP/MPLS IP VPN transparent to the customer network, as far as routing information is concerned. [STANDARDS-TRACK]
RFC6367 - Addition of the Camellia Cipher Suites to Transport Layer Security (TLS)
This document specifies forty-two cipher suites for the Transport Security Layer (TLS) protocol to support the Camellia encryption algorithm as a block cipher. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6366 - Requirements for an Internet Audio Codec
This document provides specific requirements for an Internet audio codec. These requirements address quality, sampling rate, bit-rate, and packet-loss robustness, as well as other desirable properties. This document is not an Internet Standards Track specification; it is published for informational purposes.
RFC6365 - Terminology Used in Internationalization in the IETF
This document provides a list of terms used in the IETF when discussing internationalization. The purpose is to help frame discussions of internationalization in the various areas of the IETF and to help introduce the main concepts to IETF participants. This memo documents an Internet Best Current Practice.
RFC6364 - Session Description Protocol Elements for the Forward Error Correction (FEC) Framework
This document specifies the use of the Session Description Protocol (SDP) to describe the parameters required to signal the Forward Error Correction (FEC) Framework Configuration Information between the sender(s) and receiver(s). This document also provides examples that show the semantics for grouping multiple source and repair flows together for the applications that simultaneously use multiple instances of the FEC Framework. [STANDARDS-TRACK]
RFC6363 - Forward Error Correction (FEC) Framework
This document describes a framework for using Forward Error Correction (FEC) codes with applications in public and private IP networks to provide protection against packet loss. The framework supports applying FEC to arbitrary packet flows over unreliable transport and is primarily intended for real-time, or streaming, media. This framework can be used to define Content Delivery Protocols that provide FEC for streaming media delivery or other packet flows. Content Delivery Protocols defined using this framework can support any FEC scheme (and associated FEC codes) that is compliant with various requirements defined in this document. Thus, Content Delivery Protocols can be defined that are not specific to a particular FEC scheme, and FEC schemes can be defined that are not specific to a particular Content Delivery Protocol.
