RFC Abstracts
RFC7805 - Moving Outdated TCP Extensions and TCP-Related Documents to Historic or Informational Status
This document reclassifies several TCP extensions and TCP-related documents that either have been superseded, have never seen widespread use, or are no longer recommended for use to "Historic" status. The affected documents are RFCs 675, 721, 761, 813, 816, 879, 896, 1078, and 6013. Additionally, this document reclassifies RFCs 700, 794, 814, 817, 872, 889, 964, and 1071 to "Informational" status.
RFC7804 - Salted Challenge Response HTTP Authentication Mechanism
This specification describes a family of HTTP authentication mechanisms called the Salted Challenge Response Authentication Mechanism (SCRAM), which provides a more robust authentication mechanism than a plaintext password protected by Transport Layer Security (TLS) and avoids the deployment obstacles presented by earlier TLS-protected challenge response authentication mechanisms.
RFC7803 - Changing the Registration Policy for the NETCONF Capability URNs Registry
The registration policy for the "Network Configuration Protocol (NETCONF) Capability URNs" registry, set up by RFC 6241, has turned out to be unnecessarily strict. This document changes that registration policy to "IETF Review", allowing registrations from certain well-reviewed Experimental RFCs, in addition to Standards Track RFCs.
RFC7802 - A Pseudo-Random Function (PRF) for the Kerberos V Generic Security Service Application Program Interface (GSS-API) Mechanism
This document defines the Pseudo-Random Function (PRF) for the Kerberos V mechanism for the Generic Security Service Application Program Interface (GSS-API), based on the PRF defined for the Kerberos V cryptographic framework, for keying application protocols given an established Kerberos V GSS-API security context.
RFC7801 - GOST R 34.12-2015: Block Cipher "Kuznyechik"
This document is intended to be a source of information about the Russian Federal standard GOST R 34.12-2015 describing the block cipher with a block length of n=128 bits and a key length of k=256 bits, which is also referred to as "Kuznyechik". This algorithm is one of the set of Russian cryptographic standard algorithms (called GOST algorithms).
RFC7800 - Proof-of-Possession Key Semantics for JSON Web Tokens (JWTs)
This specification describes how to declare in a JSON Web Token (JWT) that the presenter of the JWT possesses a particular proof-of- possession key and how the recipient can cryptographically confirm proof of possession of the key by the presenter. Being able to prove possession of a key is also sometimes described as the presenter being a holder-of-key.
RFC7799 - Active and Passive Metrics and Methods (with Hybrid Types In-Between)
This memo provides clear definitions for Active and Passive performance assessment. The construction of Metrics and Methods can be described as either "Active" or "Passive". Some methods may use a subset of both Active and Passive attributes, and we refer to these as "Hybrid Methods". This memo also describes multiple dimensions to help evaluate new methods as they emerge.
RFC7798 - RTP Payload Format for High Efficiency Video Coding (HEVC)
This memo describes an RTP payload format for the video coding standard ITU-T Recommendation H.265 and ISO/IEC International Standard 23008-2, both also known as High Efficiency Video Coding (HEVC) and developed by the Joint Collaborative Team on Video Coding (JCT-VC). The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload as well as fragmentation of a NAL unit into multiple RTP packets. Furthermore, it supports transmission of an HEVC bitstream over a single stream as well as multiple RTP streams. When multiple RTP streams are used, a single transport or multiple transports may be utilized. The payload format has wide applicability in videoconferencing, Internet video streaming, and high-bitrate entertainment-quality video, among others.
RFC7797 - JSON Web Signature (JWS) Unencoded Payload Option
JSON Web Signature (JWS) represents the payload of a JWS as a base64url-encoded value and uses this value in the JWS Signature computation. While this enables arbitrary payloads to be integrity protected, some have described use cases in which the base64url encoding is unnecessary and/or an impediment to adoption, especially when the payload is large and/or detached. This specification defines a means of accommodating these use cases by defining an option to change the JWS Signing Input computation to not base64url- encode the payload. This option is intended to broaden the set of use cases for which the use of JWS is a good fit.
RFC7796 - Ethernet-Tree (E-Tree) Support in Virtual Private LAN Service (VPLS)
This document specifies a generic Virtual Private LAN Service (VPLS) solution, which uses VLANs to indicate root or leaf traffic to support Ethernet-Tree (E-Tree) services. A VPLS Provider Edge (PE) model is illustrated as an example for the solution. In the solution, E-Tree VPLS PEs are interconnected by Pseudowires (PWs), which carry the VLAN indicating the E-Tree attribute. The MAC address-based Ethernet forwarding engine and the PW work in the same way as specified in RFC 4762 and RFC 4448, respectively. A signaling mechanism is described to support E-Tree capability and VLAN mapping negotiation.
RFC7795 - Pseudowire Redundancy on the Switching Provider Edge (S-PE)
This document describes Multi-Segment Pseudowire (MS-PW) protection scenarios in which pseudowire redundancy is provided on the Switching Provider Edge (S-PE) as defined in RFC 5659. Operations of the S-PEs that provide PW redundancy are specified in this document. Signaling of the Preferential Forwarding status as defined in RFCs 6870 and 6478 is reused. This document does not require any change to the Terminating Provider Edges (T-PEs) of MS-PW.
RFC7794 - IS-IS Prefix Attributes for Extended IPv4 and IPv6 Reachability
This document introduces new sub-TLVs to support advertisement of IPv4 and IPv6 prefix attribute flags and the source router ID of the router that originated a prefix advertisement.
RFC7793 - Adding 100.64.0.0/10 Prefixes to the IPv4 Locally-Served DNS Zones Registry
RFC 6598 specifies that "Reverse DNS queries for Shared Address Space addresses [100.64.0.0/10] MUST NOT be forwarded to the global DNS infrastructure."
RFC7792 - RSVP-TE Signaling Extensions in Support of Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks
This memo describes the extensions to the Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling protocol to support Label Switched Paths (LSPs) in a GMPLS-controlled network that includes devices using the flexible optical grid.
RFC7791 - Cloning the IKE Security Association in the Internet Key Exchange Protocol Version 2 (IKEv2)
This document considers a VPN end user establishing an IPsec Security Association (SA) with a Security Gateway using the Internet Key Exchange Protocol version 2 (IKEv2), where at least one of the peers has multiple interfaces or where Security Gateway is a cluster with each node having its own IP address.
RFC7790 - Mapping Characters for Classes of the Preparation, Enforcement, and Comparison of Internationalized Strings (PRECIS)
The framework for the preparation, enforcement, and comparison of internationalized strings (PRECIS) defines several classes of strings for use in application protocols. Because many protocols perform case-sensitive or case-insensitive string comparison, it is necessary to define methods for case mapping. In addition, both the Internationalized Domain Names in Applications (IDNA) and the PRECIS problem statement describe mappings for internationalized strings that are not limited to case, but include width mapping and mapping of delimiters and other special characters that can be taken into consideration. This document provides guidelines for designers of PRECIS profiles and describes several mappings that can be applied between receiving user input and passing permitted code points to internationalized protocols. In particular, this document describes both locale-dependent and context-depending case mappings as well as additional mappings for delimiters and special characters.
RFC7789 - Impact of BGP Filtering on Inter-Domain Routing Policies
This document describes how unexpected traffic flows can emerge across an autonomous system as the result of other autonomous systems filtering or restricting the propagation of more-specific prefixes. We provide a review of the techniques to detect the occurrence of this issue and defend against it.
RFC7788 - Home Networking Control Protocol
This document describes the Home Networking Control Protocol (HNCP), an extensible configuration protocol, and a set of requirements for home network devices. HNCP is described as a profile of and extension to the Distributed Node Consensus Protocol (DNCP). HNCP enables discovery of network borders, automated configuration of addresses, name resolution, service discovery, and the use of any routing protocol that supports routing based on both the source and destination address.
RFC7787 - Distributed Node Consensus Protocol
This document describes the Distributed Node Consensus Protocol (DNCP), a generic state synchronization protocol that uses the Trickle algorithm and hash trees. DNCP is an abstract protocol and must be combined with a specific profile to make a complete implementable protocol.
RFC7786 - TCP Modifications for Congestion Exposure (ConEx)
Congestion Exposure (ConEx) is a mechanism by which senders inform the network about expected congestion based on congestion feedback from previous packets in the same flow. This document describes the necessary modifications to use ConEx with the Transmission Control Protocol (TCP).
RFC7785 - Recommendations for Prefix Binding in the Context of Softwire Dual-Stack Lite
This document discusses issues induced by the change of the Dual- Stack Lite (DS-Lite) Basic Bridging BroadBand (B4) IPv6 address and sketches a set of recommendations to solve those issues.
RFC7784 - Transparent Interconnection of Lots of Links (TRILL) Operations, Administration, and Maintenance (OAM) MIB
This document specifies the MIB for the OAM (Operations, Administration, and Maintenance) objects for IETF TRILL (Transparent Interconnection of Lots of Links).
RFC7783 - Coordinated Multicast Trees (CMT) for Transparent Interconnection of Lots of Links (TRILL)
TRILL (Transparent Interconnection of Lots of Links) facilitates loop-free connectivity to non-TRILL networks via a choice of an Appointed Forwarder for a set of VLANs. Appointed Forwarders provide VLAN-based load sharing with an active-standby model. High-performance applications require an active-active load-sharing model. The active-active load-sharing model can be accomplished by representing any given non-TRILL network with a single virtual RBridge (also referred to as a virtual Routing Bridge or virtual TRILL switch). Virtual representation of the non-TRILL network with a single RBridge poses serious challenges in multi-destination RPF (Reverse Path Forwarding) check calculations. This document specifies required enhancements to build Coordinated Multicast Trees (CMT) within the TRILL campus to solve related RPF issues. CMT, which only requires a software upgrade, provides flexibility to RBridges in selecting a desired path of association to a given TRILL multi-destination distribution tree. This document updates RFC 6325.
RFC7782 - Transparent Interconnection of Lots of Links (TRILL) Active-Active Edge Using Multiple MAC Attachments
TRILL (Transparent Interconnection of Lots of Links) active-active service provides end stations with flow-level load balance and resilience against link failures at the edge of TRILL campuses, as described in RFC 7379.
RFC7781 - Transparent Interconnection of Lots of Links (TRILL): Pseudo-Nickname for Active-Active Access
The IETF TRILL (Transparent Interconnection of Lots of Links) protocol provides support for flow-level multipathing for both unicast and multi-destination traffic in networks with arbitrary topology. Active-active access at the TRILL edge is the extension of these characteristics to end stations that are multiply connected to a TRILL campus as discussed in RFC 7379. In this document, the edge RBridge (Routing Bridge, or TRILL switch) group providing active-active access to such an end station is represented as a virtual RBridge. Based on the concept of the virtual RBridge, along with its pseudo-nickname, this document specifies a method for TRILL active-active access by such end stations.
RFC7780 - Transparent Interconnection of Lots of Links (TRILL): Clarifications, Corrections, and Updates
Since the publication of the TRILL (Transparent Interconnection of Lots of Links) base protocol in 2011, active development and deployment of TRILL have revealed errata in RFC 6325 and areas that could use clarifications or updates. RFC 7177, RFC 7357, and an intended replacement of RFC 6439 provide clarifications and updates with respect to adjacency, the TRILL ESADI (End Station Address Distribution Information) protocol, and Appointed Forwarders, respectively. This document provides other known clarifications, corrections, and updates. It obsoletes RFC 7180 (the previous "TRILL clarifications, corrections, and updates" RFC), and it updates RFCs 6325, 7177, and 7179.
RFC7779 - Directional Airtime Metric Based on Packet Sequence Numbers for Optimized Link State Routing Version 2 (OLSRv2)
This document specifies a Directional Airtime (DAT) link metric for usage in Optimized Link State Routing version 2 (OLSRv2).
RFC7778 - Mobile Communication Congestion Exposure Scenario
This memo describes a mobile communications use case for congestion exposure (ConEx) with a particular focus on those mobile communication networks that are architecturally similar to the 3GPP Evolved Packet System (EPS). This memo provides a brief overview of the architecture of these networks (both access and core networks) and current QoS mechanisms and then discusses how congestion exposure concepts could be applied. Based on this discussion, this memo suggests a set of requirements for ConEx mechanisms that particularly apply to these mobile networks.
RFC7777 - Advertising Node Administrative Tags in OSPF
This document describes an extension to the OSPF protocol to add an optional operational capability that allows tagging and grouping of the nodes in an OSPF domain. This allows simplification, ease of management and control over route and path selection based on configured policies. This document describes an extension to the OSPF protocol to advertise node administrative tags. The node tags can be used to express and apply locally defined network policies, which are a very useful operational capability. Node tags may be used by either OSPF itself or other applications consuming information propagated via OSPF.
RFC7776 - IETF Anti-Harassment Procedures
IETF Participants must not engage in harassment while at IETF meetings, virtual meetings, or social events or while participating in mailing lists. This document lays out procedures for managing and enforcing this policy.
RFC7775 - IS-IS Route Preference for Extended IP and IPv6 Reachability
In existing specifications, the route preferences for IPv4/IPv6 Extended Reachability TLVs are not explicitly stated. There are also inconsistencies in the definition of how the up/down bit applies to route preference when the prefix advertisement appears in Level 2 Link State Protocol Data Units (LSPs). This document addresses these issues.
RFC7774 - Multicast Protocol for Low-Power and Lossy Networks (MPL) Parameter Configuration Option for DHCPv6
This document defines a way to configure a parameter set for MPL (Multicast Protocol for Low-Power and Lossy Networks) via a DHCPv6 option. MPL has a set of parameters to control its behavior, and the parameter set is often configured as a network-wide parameter because the parameter set should be identical for each MPL Forwarder in an MPL Domain. Using the MPL Parameter Configuration Option defined in this document, a network can easily be configured with a single set of MPL parameters.
RFC7773 - Authentication Context Certificate Extension
This document defines an extension to X.509 certificates. The extension defined in this document holds data about how the certificate subject was authenticated by the Certification Authority that issued the certificate in which this extension appears.
RFC7772 - Reducing Energy Consumption of Router Advertisements
Frequent Router Advertisement messages can severely impact host power consumption. This document recommends operational practices to avoid such impact.
RFC7771 - Switching Provider Edge (S-PE) Protection for MPLS and MPLS Transport Profile (MPLS-TP) Static Multi-Segment Pseudowires
In MPLS and MPLS Transport Profile (MPLS-TP) environments, statically provisioned Single-Segment Pseudowires (SS-PWs) are protected against tunnel failure via MPLS-level and MPLS-TP-level tunnel protection. With statically provisioned Multi-Segment Pseudowires (MS-PWs), each segment of the MS-PW is likewise protected from tunnel failures via MPLS-level and MPLS-TP-level tunnel protection. However, static MS-PWs are not protected end-to-end against failure of one of the Switching Provider Edge Routers (S-PEs) along the path of the MS-PW. This document describes how to achieve this protection via redundant MS-PWs by updating the existing procedures in RFC 6870. It also contains an optional approach based on MPLS-TP Linear Protection.
RFC7770 - Extensions to OSPF for Advertising Optional Router Capabilities
It is useful for routers in an OSPFv2 or OSPFv3 routing domain to know the capabilities of their neighbors and other routers in the routing domain. This document proposes extensions to OSPFv2 and OSPFv3 for advertising optional router capabilities. The Router Information (RI) Link State Advertisement (LSA) is defined for this purpose. In OSPFv2, the RI LSA will be implemented with an Opaque LSA type ID. In OSPFv3, the RI LSA will be implemented with a unique LSA type function code. In both protocols, the RI LSA can be advertised at any of the defined flooding scopes (link, area, or autonomous system (AS)). This document obsoletes RFC 4970 by providing a revised specification that includes support for advertisement of multiple instances of the RI LSA and a TLV for functional capabilities.
RFC7769 - Media Access Control (MAC) Address Withdrawal over Static Pseudowire
This document specifies a mechanism to signal Media Access Control (MAC) address withdrawal notification using a pseudowire (PW) Associated Channel (ACH). Such notification is useful when statically provisioned PWs are deployed in a Virtual Private LAN Service (VPLS) or Hierarchical Virtual Private LAN Service (H-VPLS) environment.
RFC7768 - Port Management to Reduce Logging in Large-Scale NATs
Various IPv6 transition strategies require the introduction of large- scale NATs (e.g., AFTR and NAT64) to share the limited supply of IPv4 addresses available in the network until transition is complete. There has recently been debate over how to manage the sharing of ports between different subscribers sharing the same IPv4 address. One factor in the discussion is the operational requirement to log the assignment of transport addresses to subscribers. It has been argued that dynamic assignment of individual ports between subscribers requires the generation of an excessive volume of logs. This document suggests a way to achieve dynamic port sharing while keeping log volumes low.
RFC7767 - Application-Initiated Check-Pointing via the Port Control Protocol (PCP)
This document specifies a mechanism for a host to indicate via the Port Control Protocol (PCP) which connections should be protected against network failures. These connections will then be subject to high-availability mechanisms enabled on the network side.
RFC7766 - DNS Transport over TCP - Implementation Requirements
This document specifies the requirement for support of TCP as a transport protocol for DNS implementations and provides guidelines towards DNS-over-TCP performance on par with that of DNS-over-UDP. This document obsoletes RFC 5966 and therefore updates RFC 1035 and RFC 1123.
RFC7765 - TCP and Stream Control Transmission Protocol (SCTP) RTO Restart
This document describes a modified sender-side algorithm for managing the TCP and Stream Control Transmission Protocol (SCTP) retransmission timers that provides faster loss recovery when there is a small amount of outstanding data for a connection. The modification, RTO Restart (RTOR), allows the transport to restart its retransmission timer using a smaller timeout duration, so that the effective retransmission timeout (RTO) becomes more aggressive in situations where fast retransmit cannot be used. This enables faster loss detection and recovery for connections that are short lived or application limited.
RFC7764 - Guidance on Markdown: Design Philosophies, Stability Strategies, and Select Registrations
This document elaborates upon the text/markdown media type for use with Markdown, a family of plain-text formatting syntaxes that optionally can be converted to formal markup languages such as HTML. Background information, local storage strategies, and additional syntax registrations are supplied.
RFC7763 - The text/markdown Media Type
This document registers the text/markdown media type for use with Markdown, a family of plain-text formatting syntaxes that optionally can be converted to formal markup languages such as HTML.
RFC7762 - Initial Assignment for the Content Security Policy Directives Registry
This document establishes an Internet Assigned Number Authority (IANA) registry for Content Security Policy directives and populates that registry with the directives defined in the Content Security Policy Level 2 specification.
RFC7761 - Protocol Independent Multicast - Sparse Mode (PIM-SM): Protocol Specification (Revised)
This document specifies Protocol Independent Multicast - Sparse Mode (PIM-SM). PIM-SM is a multicast routing protocol that can use the underlying unicast routing information base or a separate multicast-capable routing information base. It builds unidirectional shared trees rooted at a Rendezvous Point (RP) per group, and it optionally creates shortest-path trees per source.
RFC7760 - Statement of Work for Extensions to the IETF Datatracker for Author Statistics
This is the Statement of Work (SOW) for extensions to the IETF Datatracker to provide statistics about RFCs and Internet-Drafts and their authors.
RFC7759 - Configuration of Proactive Operations, Administration, and Maintenance (OAM) Functions for MPLS-Based Transport Networks Using Label Switched Path (LSP) Ping
This specification describes the configuration of proactive MPLS-TP Operations, Administration, and Maintenance (OAM) functions for a given Label Switched Path (LSP) using a set of TLVs that are carried by the LSP Ping protocol.
RFC7758 - Time Capability in NETCONF
This document defines a capability-based extension to the Network Configuration Protocol (NETCONF) that allows time-triggered configuration and management operations. This extension allows NETCONF clients to invoke configuration updates according to scheduled times and allows NETCONF servers to attach timestamps to the data they send to NETCONF clients.
RFC7757 - Explicit Address Mappings for Stateless IP/ICMP Translation
This document extends the Stateless IP/ICMP Translation Algorithm (SIIT) with an Explicit Address Mapping (EAM) algorithm and formally updates RFC 6145. The EAM algorithm facilitates stateless IP/ICMP translation between arbitrary (non-IPv4-translatable) IPv6 endpoints and IPv4.
RFC7756 - Stateless IP/ICMP Translation for IPv6 Internet Data Center Environments (SIIT-DC): Dual Translation Mode
This document describes an extension of the Stateless IP/ICMP Translation for IPv6 Internet Data Center Environments (SIIT-DC) architecture, which allows applications, protocols, or nodes that are incompatible with IPv6 and/or Network Address Translation to operate correctly with SIIT-DC. This is accomplished by introducing a new component called an SIIT-DC Edge Relay, which reverses the translations made by an SIIT-DC Border Relay. The application and/or node is thus provided with seemingly native IPv4 connectivity that provides end-to-end address transparency.
This document reclassifies several TCP extensions and TCP-related documents that either have been superseded, have never seen widespread use, or are no longer recommended for use to "Historic" status. The affected documents are RFCs 675, 721, 761, 813, 816, 879, 896, 1078, and 6013. Additionally, this document reclassifies RFCs 700, 794, 814, 817, 872, 889, 964, and 1071 to "Informational" status.

RFC7781 - Transparent Interconnection of Lots of Links (TRILL): Pseudo-Nickname for Active-Active Access
The IETF TRILL (Transparent Interconnection of Lots of Links) protocol provides support for flow-level multipathing for both unicast and multi-destination traffic in networks with arbitrary topology. Active-active access at the TRILL edge is the extension of these characteristics to end stations that are multiply connected to a TRILL campus as discussed in RFC 7379. In this document, the edge RBridge (Routing Bridge, or TRILL switch) group providing active-active access to such an end station is represented as a virtual RBridge. Based on the concept of the virtual RBridge, along with its pseudo-nickname, this document specifies a method for TRILL active-active access by such end stations.
RFC7780 - Transparent Interconnection of Lots of Links (TRILL): Clarifications, Corrections, and Updates
Since the publication of the TRILL (Transparent Interconnection of Lots of Links) base protocol in 2011, active development and deployment of TRILL have revealed errata in RFC 6325 and areas that could use clarifications or updates. RFC 7177, RFC 7357, and an intended replacement of RFC 6439 provide clarifications and updates with respect to adjacency, the TRILL ESADI (End Station Address Distribution Information) protocol, and Appointed Forwarders, respectively. This document provides other known clarifications, corrections, and updates. It obsoletes RFC 7180 (the previous "TRILL clarifications, corrections, and updates" RFC), and it updates RFCs 6325, 7177, and 7179.
RFC7779 - Directional Airtime Metric Based on Packet Sequence Numbers for Optimized Link State Routing Version 2 (OLSRv2)
This document specifies a Directional Airtime (DAT) link metric for usage in Optimized Link State Routing version 2 (OLSRv2).
RFC7778 - Mobile Communication Congestion Exposure Scenario
This memo describes a mobile communications use case for congestion exposure (ConEx) with a particular focus on those mobile communication networks that are architecturally similar to the 3GPP Evolved Packet System (EPS). This memo provides a brief overview of the architecture of these networks (both access and core networks) and current QoS mechanisms and then discusses how congestion exposure concepts could be applied. Based on this discussion, this memo suggests a set of requirements for ConEx mechanisms that particularly apply to these mobile networks.
RFC7777 - Advertising Node Administrative Tags in OSPF
This document describes an extension to the OSPF protocol to add an optional operational capability that allows tagging and grouping of the nodes in an OSPF domain. This allows simplification, ease of management and control over route and path selection based on configured policies. This document describes an extension to the OSPF protocol to advertise node administrative tags. The node tags can be used to express and apply locally defined network policies, which are a very useful operational capability. Node tags may be used by either OSPF itself or other applications consuming information propagated via OSPF.
RFC7776 - IETF Anti-Harassment Procedures
IETF Participants must not engage in harassment while at IETF meetings, virtual meetings, or social events or while participating in mailing lists. This document lays out procedures for managing and enforcing this policy.
RFC7775 - IS-IS Route Preference for Extended IP and IPv6 Reachability
In existing specifications, the route preferences for IPv4/IPv6 Extended Reachability TLVs are not explicitly stated. There are also inconsistencies in the definition of how the up/down bit applies to route preference when the prefix advertisement appears in Level 2 Link State Protocol Data Units (LSPs). This document addresses these issues.
RFC7774 - Multicast Protocol for Low-Power and Lossy Networks (MPL) Parameter Configuration Option for DHCPv6
This document defines a way to configure a parameter set for MPL (Multicast Protocol for Low-Power and Lossy Networks) via a DHCPv6 option. MPL has a set of parameters to control its behavior, and the parameter set is often configured as a network-wide parameter because the parameter set should be identical for each MPL Forwarder in an MPL Domain. Using the MPL Parameter Configuration Option defined in this document, a network can easily be configured with a single set of MPL parameters.
RFC7773 - Authentication Context Certificate Extension
This document defines an extension to X.509 certificates. The extension defined in this document holds data about how the certificate subject was authenticated by the Certification Authority that issued the certificate in which this extension appears.
RFC7772 - Reducing Energy Consumption of Router Advertisements
Frequent Router Advertisement messages can severely impact host power consumption. This document recommends operational practices to avoid such impact.
RFC7771 - Switching Provider Edge (S-PE) Protection for MPLS and MPLS Transport Profile (MPLS-TP) Static Multi-Segment Pseudowires
In MPLS and MPLS Transport Profile (MPLS-TP) environments, statically provisioned Single-Segment Pseudowires (SS-PWs) are protected against tunnel failure via MPLS-level and MPLS-TP-level tunnel protection. With statically provisioned Multi-Segment Pseudowires (MS-PWs), each segment of the MS-PW is likewise protected from tunnel failures via MPLS-level and MPLS-TP-level tunnel protection. However, static MS-PWs are not protected end-to-end against failure of one of the Switching Provider Edge Routers (S-PEs) along the path of the MS-PW. This document describes how to achieve this protection via redundant MS-PWs by updating the existing procedures in RFC 6870. It also contains an optional approach based on MPLS-TP Linear Protection.
RFC7770 - Extensions to OSPF for Advertising Optional Router Capabilities
It is useful for routers in an OSPFv2 or OSPFv3 routing domain to know the capabilities of their neighbors and other routers in the routing domain. This document proposes extensions to OSPFv2 and OSPFv3 for advertising optional router capabilities. The Router Information (RI) Link State Advertisement (LSA) is defined for this purpose. In OSPFv2, the RI LSA will be implemented with an Opaque LSA type ID. In OSPFv3, the RI LSA will be implemented with a unique LSA type function code. In both protocols, the RI LSA can be advertised at any of the defined flooding scopes (link, area, or autonomous system (AS)). This document obsoletes RFC 4970 by providing a revised specification that includes support for advertisement of multiple instances of the RI LSA and a TLV for functional capabilities.
RFC7769 - Media Access Control (MAC) Address Withdrawal over Static Pseudowire
This document specifies a mechanism to signal Media Access Control (MAC) address withdrawal notification using a pseudowire (PW) Associated Channel (ACH). Such notification is useful when statically provisioned PWs are deployed in a Virtual Private LAN Service (VPLS) or Hierarchical Virtual Private LAN Service (H-VPLS) environment.
RFC7768 - Port Management to Reduce Logging in Large-Scale NATs
Various IPv6 transition strategies require the introduction of large- scale NATs (e.g., AFTR and NAT64) to share the limited supply of IPv4 addresses available in the network until transition is complete. There has recently been debate over how to manage the sharing of ports between different subscribers sharing the same IPv4 address. One factor in the discussion is the operational requirement to log the assignment of transport addresses to subscribers. It has been argued that dynamic assignment of individual ports between subscribers requires the generation of an excessive volume of logs. This document suggests a way to achieve dynamic port sharing while keeping log volumes low.
RFC7767 - Application-Initiated Check-Pointing via the Port Control Protocol (PCP)
This document specifies a mechanism for a host to indicate via the Port Control Protocol (PCP) which connections should be protected against network failures. These connections will then be subject to high-availability mechanisms enabled on the network side.
RFC7766 - DNS Transport over TCP - Implementation Requirements
This document specifies the requirement for support of TCP as a transport protocol for DNS implementations and provides guidelines towards DNS-over-TCP performance on par with that of DNS-over-UDP. This document obsoletes RFC 5966 and therefore updates RFC 1035 and RFC 1123.
RFC7765 - TCP and Stream Control Transmission Protocol (SCTP) RTO Restart
This document describes a modified sender-side algorithm for managing the TCP and Stream Control Transmission Protocol (SCTP) retransmission timers that provides faster loss recovery when there is a small amount of outstanding data for a connection. The modification, RTO Restart (RTOR), allows the transport to restart its retransmission timer using a smaller timeout duration, so that the effective retransmission timeout (RTO) becomes more aggressive in situations where fast retransmit cannot be used. This enables faster loss detection and recovery for connections that are short lived or application limited.
RFC7764 - Guidance on Markdown: Design Philosophies, Stability Strategies, and Select Registrations
This document elaborates upon the text/markdown media type for use with Markdown, a family of plain-text formatting syntaxes that optionally can be converted to formal markup languages such as HTML. Background information, local storage strategies, and additional syntax registrations are supplied.
RFC7763 - The text/markdown Media Type
This document registers the text/markdown media type for use with Markdown, a family of plain-text formatting syntaxes that optionally can be converted to formal markup languages such as HTML.
RFC7762 - Initial Assignment for the Content Security Policy Directives Registry
This document establishes an Internet Assigned Number Authority (IANA) registry for Content Security Policy directives and populates that registry with the directives defined in the Content Security Policy Level 2 specification.
RFC7761 - Protocol Independent Multicast - Sparse Mode (PIM-SM): Protocol Specification (Revised)
This document specifies Protocol Independent Multicast - Sparse Mode (PIM-SM). PIM-SM is a multicast routing protocol that can use the underlying unicast routing information base or a separate multicast-capable routing information base. It builds unidirectional shared trees rooted at a Rendezvous Point (RP) per group, and it optionally creates shortest-path trees per source.
RFC7760 - Statement of Work for Extensions to the IETF Datatracker for Author Statistics
This is the Statement of Work (SOW) for extensions to the IETF Datatracker to provide statistics about RFCs and Internet-Drafts and their authors.
RFC7759 - Configuration of Proactive Operations, Administration, and Maintenance (OAM) Functions for MPLS-Based Transport Networks Using Label Switched Path (LSP) Ping
This specification describes the configuration of proactive MPLS-TP Operations, Administration, and Maintenance (OAM) functions for a given Label Switched Path (LSP) using a set of TLVs that are carried by the LSP Ping protocol.
RFC7758 - Time Capability in NETCONF
This document defines a capability-based extension to the Network Configuration Protocol (NETCONF) that allows time-triggered configuration and management operations. This extension allows NETCONF clients to invoke configuration updates according to scheduled times and allows NETCONF servers to attach timestamps to the data they send to NETCONF clients.
RFC7757 - Explicit Address Mappings for Stateless IP/ICMP Translation
This document extends the Stateless IP/ICMP Translation Algorithm (SIIT) with an Explicit Address Mapping (EAM) algorithm and formally updates RFC 6145. The EAM algorithm facilitates stateless IP/ICMP translation between arbitrary (non-IPv4-translatable) IPv6 endpoints and IPv4.
RFC7756 - Stateless IP/ICMP Translation for IPv6 Internet Data Center Environments (SIIT-DC): Dual Translation Mode
This document describes an extension of the Stateless IP/ICMP Translation for IPv6 Internet Data Center Environments (SIIT-DC) architecture, which allows applications, protocols, or nodes that are incompatible with IPv6 and/or Network Address Translation to operate correctly with SIIT-DC. This is accomplished by introducing a new component called an SIIT-DC Edge Relay, which reverses the translations made by an SIIT-DC Border Relay. The application and/or node is thus provided with seemingly native IPv4 connectivity that provides end-to-end address transparency.
