RFC7254 - A Uniform Resource Name Namespace for the Global System for Mobile Communications Association (GSMA) and the International Mobile station Equipment Identity (IMEI)
This specification defines a Uniform Resource Name (URN) namespace for the Global System for Mobile Communications Association (GSMA) and a Namespace Specific String (NSS) for the International Mobile station Equipment Identity (IMEI), as well as an associated parameter for the International Mobile station Equipment Identity and Software Version number (IMEISV). The IMEI and IMEISV were introduced as part of the specification for the GSM and are also now incorporated by the 3rd Generation Partnership Project (3GPP) as part of the 3GPP specification for GSM, Universal Mobile Telecommunications System (UMTS), and 3GPP Long Term Evolution (LTE) networks. The IMEI and IMEISV are used to uniquely identify Mobile Equipment within these systems and are managed by the GSMA. URNs from this namespace almost always contain personally identifiable information and need to be treated accordingly.
RFC7253 - The OCB Authenticated-Encryption Algorithm
This document specifies OCB, a shared-key blockcipher-based encryption scheme that provides confidentiality and authenticity for plaintexts and authenticity for associated data. This document is a product of the Crypto Forum Research Group (CFRG).
RFC7252 - The Constrained Application Protocol (CoAP)
The Constrained Application Protocol (CoAP) is a specialized web transfer protocol for use with constrained nodes and constrained (e.g., low-power, lossy) networks. The nodes often have 8-bit microcontrollers with small amounts of ROM and RAM, while constrained networks such as IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs) often have high packet error rates and a typical throughput of 10s of kbit/s. The protocol is designed for machine- to-machine (M2M) applications such as smart energy and building automation.
RFC7251 - AES-CCM Elliptic Curve Cryptography (ECC) Cipher Suites for TLS
This memo describes the use of the Advanced Encryption Standard (AES) in the Counter and CBC-MAC Mode (CCM) of operation within Transport Layer Security (TLS) to provide confidentiality and data-origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments, while at the same time providing a high level of security. The cipher suites defined in this document use Elliptic Curve Cryptography (ECC) and are advantageous in networks with limited bandwidth.
RFC7250 - Using Raw Public Keys in Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS)
This document specifies a new certificate type and two TLS extensions for exchanging raw public keys in Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS). The new certificate type allows raw public keys to be used for authentication.
RFC7249 - Internet Numbers Registries

RFC7248 - Interworking between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP): Presence
This document defines a bidirectional protocol mapping for the exchange of presence information between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP).
RFC7247 - Interworking between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP): Architecture, Addresses, and Error Handling
As a foundation for the definition of bidirectional protocol mappings between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP), this document specifies the architectural assumptions underlying such mappings as well as the mapping of addresses and error conditions.
RFC7246 - Multipoint Label Distribution Protocol In-Band Signaling in a Virtual Routing and Forwarding (VRF) Table Context
An IP Multicast Distribution Tree (MDT) may traverse both label switching (i.e., Multiprotocol Label Switching, or MPLS) and non-label switching regions of a network. Typically, the MDT begins and ends in non-MPLS regions, but travels through an MPLS region. In such cases, it can be useful to begin building the MDT as a pure IP MDT, then convert it to an MPLS Multipoint Label Switched Path (MP-LSP) when it enters an MPLS-enabled region, and then convert it back to a pure IP MDT when it enters a non-MPLS-enabled region. Other documents specify the procedures for building such a hybrid MDT, using Protocol Independent Multicast (PIM) in the non-MPLS region of the network, and using Multipoint Label Distribution Protocol (mLDP) in the MPLS region. This document extends those procedures to handle the case where the link connecting the two regions is a Virtual Routing and Forwarding (VRF) table link, as defined in the "BGP IP/MPLS VPN" specification. However, this document is primarily aimed at particular use cases where VRFs are used to support multicast applications other than multicast VPN.
RFC7245 - An Architecture for Media Recording Using the Session Initiation Protocol
Session recording is a critical requirement in many communications environments such as call centers and financial trading. In some of these environments, all calls must be recorded for regulatory, compliance, and consumer protection reasons. Recording of a session is typically performed by sending a copy of a media stream to a recording device. This document describes architectures for deploying session recording solutions in an environment that is based on the Session Initiation Protocol (SIP).
RFC7244 - RTP Control Protocol (RTCP) Extended Report (XR) Blocks for Synchronization Delay and Offset Metrics Reporting
This document defines two RTP Control Protocol (RTCP) Extended Report (XR) blocks that allow the reporting of initial synchronization delay and synchronization offset metrics for use in a range of RTP applications.
RFC7243 - RTP Control Protocol (RTCP) Extended Report (XR) Block for the Bytes Discarded Metric
The RTP Control Protocol (RTCP) is used in conjunction with the Real-time Transport Protocol (RTP) to provide a variety of short-term and long-term reception statistics. The available reporting may include aggregate information across longer periods of time as well as individual packet reporting. This document specifies a report computing the bytes discarded from the de-jitter buffer after successful reception.
RFC7242 - Delay-Tolerant Networking TCP Convergence-Layer Protocol
This document describes the protocol for the TCP-based convergence layer for Delay-Tolerant Networking (DTN). It is the product of the IRTF's DTN Research Group (DTNRG).
RFC7241 - The IEEE 802/IETF Relationship
This document describes the standardization cooperation between Project 802 of the Institute of Electrical and Electronics Engineers (IEEE) and the Internet Engineering Task Force (IETF). This document obsoletes RFC 4441.

The Hypertext Transfer Protocol (HTTP) is a stateless application- level protocol for distributed, collaborative, hypertext information systems. This document defines HTTP/1.1 conditional requests, including metadata header fields for indicating state changes, request header fields for making preconditions on such state, and rules for constructing the responses to a conditional request when one or more preconditions evaluate to false.
RFC7231 - Hypertext Transfer Protocol (HTTP/1.1): Semantics and Content
The Hypertext Transfer Protocol (HTTP) is a stateless \%application- level protocol for distributed, collaborative, hypertext information systems. This document defines the semantics of HTTP/1.1 messages, as expressed by request methods, request header fields, response status codes, and response header fields, along with the payload of messages (metadata and body content) and mechanisms for content negotiation.
RFC7230 - Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing
The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document provides an overview of HTTP architecture and its associated terminology, defines the "http" and "https" Uniform Resource Identifier (URI) schemes, defines the HTTP/1.1 message syntax and parsing requirements, and describes related security concerns for implementations.
RFC7229 - Object Identifiers for Test Certificate Policies
This document provides several certificate policy identifiers for testing certificate handling software.
RFC7228 - Terminology for Constrained-Node Networks
The Internet Protocol Suite is increasingly used on small devices with severe constraints on power, memory, and processing resources, creating constrained-node networks. This document provides a number of basic terms that have been useful in the standardization work for constrained-node networks.
RFC7227 - Guidelines for Creating New DHCPv6 Options
This document provides guidance to prospective DHCPv6 option developers to help them create option formats that are easily adoptable by existing DHCPv6 software. It also provides guidelines for expert reviewers to evaluate new registrations. This document updates RFC 3315.
RFC7226 - Requirements for Advanced Multipath in MPLS Networks
This document provides a set of requirements for Advanced Multipath in MPLS networks.
RFC7225 - Discovering NAT64 IPv6 Prefixes Using the Port Control Protocol (PCP)
This document defines a new Port Control Protocol (PCP) option to learn the IPv6 prefix(es) used by a PCP-controlled NAT64 device to build IPv4-converted IPv6 addresses. This option is needed for successful communications when IPv4 addresses are used in referrals.
RFC7224 - IANA Interface Type YANG Module
This document defines the initial version of the iana-if-type YANG module.
RFC7223 - A YANG Data Model for Interface Management
This document defines a YANG data model for the management of network interfaces. It is expected that interface-type-specific data models augment the generic interfaces data model defined in this document. The data model includes configuration data and state data (status information and counters for the collection of statistics).
RFC7222 - Quality-of-Service Option for Proxy Mobile IPv6
This specification defines a new mobility option, the Quality-of- Service (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node's IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the local mobility anchor and the mobile access gateway. Furthermore, making QoS parameters available on the mobile access gateway enables mapping of these parameters to QoS rules that are specific to the access technology and allows those rules to be enforced on the access network using access-technology-specific approaches.
RFC7221 - Handling of Internet-Drafts by IETF Working Groups
The productive output of an IETF working group is documents, as mandated by the working group's charter. When a working group is ready to develop a particular document, the most common mechanism is for it to "adopt" an existing document as a starting point. The document that a working group adopts and then develops further is based on initial input at varying levels of maturity. An initial working group draft might be a document already in wide use, or it might be a blank sheet, wholly created by the working group, or it might represent any level of maturity in between. This document discusses how a working group typically handles the formal documents that it targets for publication.
RFC7220 - Description Option for the Port Control Protocol (PCP)
This document extends the Port Control Protocol (PCP) with the ability to associate a description with a PCP-instantiated mapping. It does this by defining a new DESCRIPTION option.
RFC7219 - SEcure Neighbor Discovery (SEND) Source Address Validation Improvement (SAVI)
This memo specifies SEcure Neighbor Discovery (SEND) Source Address Validation Improvement (SAVI), a mechanism to provide source address validation using the SEND protocol. The proposed mechanism complements ingress filtering techniques to provide a finer granularity on the control of IPv6 source addresses.
RFC7218 - Adding Acronyms to Simplify Conversations about DNS-Based Authentication of Named Entities (DANE)
Experience has shown that people get confused when discussing the three numeric fields of the TLSA record. This document specifies descriptive acronyms for the three numeric fields in TLSA records. This document updates the format of the IANA registry created by RFC 6698.
RFC7217 - A Method for Generating Semantically Opaque Interface Identifiers with IPv6 Stateless Address Autoconfiguration (SLAAC)
This document specifies a method for generating IPv6 Interface Identifiers to be used with IPv6 Stateless Address Autoconfiguration (SLAAC), such that an IPv6 address configured using this method is stable within each subnet, but the corresponding Interface Identifier changes when the host moves from one network to another. This method is meant to be an alternative to generating Interface Identifiers based on hardware addresses (e.g., IEEE LAN Media Access Control (MAC) addresses), such that the benefits of stable addresses can be achieved without sacrificing the security and privacy of users. The method specified in this document applies to all prefixes a host may be employing, including link-local, global, and unique-local prefixes (and their corresponding addresses).
RFC7216 - Location Information Server (LIS) Discovery Using IP Addresses and Reverse DNS
The residential gateway is a device that has become an integral part of home networking equipment. Discovering a Location Information Server (LIS) is a necessary part of acquiring location information for location-based services. However, discovering a LIS when a residential gateway is present poses a configuration challenge, requiring a method that is able to work around the obstacle presented by the gateway.
RFC7215 - Locator/Identifier Separation Protocol (LISP) Network Element Deployment Considerations
This document is a snapshot of different Locator/Identifier Separation Protocol (LISP) deployment scenarios. It discusses the placement of new network elements introduced by the protocol, representing the thinking of the LISP working group as of Summer 2013. LISP deployment scenarios may have evolved since then. This memo represents one stable point in that evolution of understanding.
RFC7214 - Moving Generic Associated Channel (G-ACh) IANA Registries to a New Registry
RFC 5586 generalized the applicability of the pseudowire Associated Channel Header (PW-ACH) into the Generic Associated Channel G-ACh. However, registries and allocations of G-ACh parameters had been distributed throughout different, sometimes unrelated, registries. This document coalesces these into a new "Generic Associated Channel (G-ACh) Parameters" registry under the "Multiprotocol Label Switching Architecture (MPLS)" heading. This document updates RFC 5586.
RFC7213 - MPLS Transport Profile (MPLS-TP) Next-Hop Ethernet Addressing
The MPLS Transport Profile (MPLS-TP) is the set of MPLS protocol functions applicable to the construction and operation of packet- switched transport networks. This document presents considerations for link-layer addressing of Ethernet frames carrying MPLS-TP packets.
RFC7212 - MPLS Generic Associated Channel (G-ACh) Advertisement Protocol
The MPLS Generic Associated Channel (G-ACh) provides an auxiliary logical data channel associated with a Label Switched Path (LSP), a pseudowire, or a section (link) over which a variety of protocols may flow. These protocols are commonly used to provide Operations, Administration, and Maintenance (OAM) mechanisms associated with the primary data channel. This document specifies simple procedures by which an endpoint of an LSP, pseudowire, or section may inform the other endpoints of its capabilities and configuration parameters, or other application-specific information. This information may then be used by the receiver to validate or adjust its local configuration, and by the network operator for diagnostic purposes.
RFC7211 - Operations Model for Router Keying
The IETF is engaged in an effort to analyze the security of routing protocol authentication according to design guidelines discussed in RFC 6518, "Keying and Authentication for Routing Protocols (KARP) Design Guidelines". Developing an operational and management model for routing protocol security that works with all the routing protocols will be critical to the deployability of these efforts. This document gives recommendations to operators and implementors regarding management and operation of router authentication. These recommendations will also assist protocol designers in understanding management issues they will face.
RFC7210 - Database of Long-Lived Symmetric Cryptographic Keys
This document specifies the information contained in a conceptual database of long-lived cryptographic keys used by many different routing protocols for message security. The database is designed to support both manual and automated key management. In addition to describing the schema for the database, this document describes the operations that can be performed on the database as well as the requirements for the routing protocols that wish to use the database. In many typical scenarios, the protocols do not directly use the long-lived key, but rather a key derivation function is used to derive a short-lived key from a long-lived key.
RFC7209 - Requirements for Ethernet VPN (EVPN)
The widespread adoption of Ethernet L2VPN services and the advent of new applications for the technology (e.g., data center interconnect) have culminated in a new set of requirements that are not readily addressable by the current Virtual Private LAN Service (VPLS) solution. In particular, multihoming with all-active forwarding is not supported, and there's no existing solution to leverage Multipoint-to-Multipoint (MP2MP) Label Switched Paths (LSPs) for optimizing the delivery of multi-destination frames. Furthermore, the provisioning of VPLS, even in the context of BGP-based auto-discovery, requires network operators to specify various network parameters on top of the access configuration. This document specifies the requirements for an Ethernet VPN (EVPN) solution, which addresses the above issues.
RFC7208 - Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1
Email on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the "MAIL FROM" of a message or the domain given on the SMTP HELO/EHLO commands. This document describes version 1 of the Sender Policy Framework (SPF) protocol, whereby ADministrative Management Domains (ADMDs) can explicitly authorize the hosts that are allowed to use their domain names, and a receiving host can check such authorization.
RFC7207 - A Uniform Resource Name (URN) Namespace for Eurosystem Messaging
This document defines and registers with IANA a Uniform Resource Name (URN) namespace for usage within messages standardized by the Eurosystem. The URN namespace is managed by Deutsche Bundesbank, which is a member of the European System of Central Banks (ESCB).
RFC7206 - Requirements for an End-to-End Session Identification in IP-Based Multimedia Communication Networks
This document specifies the requirements for an end-to-end session identifier in IP-based multimedia communication networks. This identifier would enable endpoints, intermediate devices, and management and monitoring systems to identify a session end-to-end across multiple SIP devices, hops, and administrative domains.
RFC7205 - Use Cases for Telepresence Multistreams
Telepresence conferencing systems seek to create an environment that gives users (or user groups) that are not co-located a feeling of co-located presence through multimedia communication that includes at least audio and video signals of high fidelity. A number of techniques for handling audio and video streams are used to create this experience. When these techniques are not similar, interoperability between different systems is difficult at best, and often not possible. Conveying information about the relationships between multiple streams of media would enable senders and receivers to make choices to allow telepresence systems to interwork. This memo describes the most typical and important use cases for sending multiple streams in a telepresence conference.
