RFC Abstracts
RFC8079 - Guidelines for End-to-End Support of the RTP Control Protocol (RTCP) in Back-to-Back User Agents (B2BUAs)
SIP Back-to-Back User Agents (B2BUAs) are often designed to also be on the media path, rather than just to intercept signalling. This means that B2BUAs often implement an RTP or RTP Control Protocol (RTCP) stack as well, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP messages get lost because of mismatches in the reported data.
RFC8078 - Managing DS Records from the Parent via CDS/CDNSKEY
RFC 7344 specifies how DNS trust can be maintained across key rollovers in-band between parent and child. This document elevates RFC 7344 from Informational to Standards Track. It also adds a method for initial trust setup and removal of a secure entry point.
RFC8077 - Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)
Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, and Ethernet) can be emulated over an MPLS backbone by encapsulating the Layer 2 Protocol Data Units (PDUs) and then transmitting them over pseudowires (PWs). It is also possible to use pseudowires to provide low-rate Time-Division Multiplexed and Synchronous Optical NETworking circuit emulation over an MPLS-enabled network. This document specifies a protocol for establishing and maintaining the pseudowires, using extensions to the Label Distribution Protocol (LDP). Procedures for encapsulating Layer 2 PDUs are specified in other documents.
RFC8076 - A Usage for Shared Resources in RELOAD (ShaRe)
This document defines a REsource LOcation And Discovery (RELOAD) Usage for managing shared write access to RELOAD Resources. Shared Resources in RELOAD (ShaRe) form a basic primitive for enabling various coordination and notification schemes among distributed peers. Access in ShaRe is controlled by a hierarchical trust delegation scheme maintained within an access list. A new USER-CHAIN-ACL access policy allows authorized peers to write a Shared Resource without owning its corresponding certificate. This specification also adds mechanisms to store Resources with a variable name that is useful whenever peer-independent rendezvous processes are required.
RFC8075 - Guidelines for Mapping Implementations: HTTP to the Constrained Application Protocol (CoAP)
This document provides reference information for implementing a cross-protocol network proxy that performs translation from the HTTP protocol to the Constrained Application Protocol (CoAP). This will enable an HTTP client to access resources on a CoAP server through the proxy. This document describes how an HTTP request is mapped to a CoAP request and how a CoAP response is mapped back to an HTTP response. This includes guidelines for status code, URI, and media type mappings, as well as additional interworking advice.
RFC8074 - Source Address Validation Improvement (SAVI) for Mixed Address Assignment Methods Scenario
In networks that use multiple techniques for address assignment, the spoofing of addresses assigned by each technique can be prevented using the appropriate Source Address Validation Improvement (SAVI) methods. This document reviews how multiple SAVI methods can coexist in a single SAVI device and how collisions are resolved when the same binding entry is discovered by two or more methods.
RFC8073 - Coordinating Attack Response at Internet Scale (CARIS) Workshop Report
This report documents the discussions and conclusions from the Coordinating Attack Response at Internet Scale (CARIS) workshop that took place in Berlin, Germany on 18 June 2015.

This document describes how to further extend the Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) extension (defined in RFC 4556) to exchange an opaque data blob that a Key Distribution Center (KDC) can validate to ensure that the client is currently in possession of the private key during a PKINIT Authentication Service (AS) exchange.
RFC8069 - URN Namespace for IEEE
This document describes the Namespace Identifier (NID) 'ieee' for Uniform Resource Names (URNs) used to identify resources published by the Institute of Electrical and Electronics Engineers (IEEE). IEEE specifies and manages resources that utilize this URN identification model. Management activities for these and other resources types are handled by the manager of the IEEE Registration Authority.
RFC8068 - Session Initiation Protocol (SIP) Recording Call Flows
Session recording is a critical requirement in many communications environments, such as call centers and financial trading organizations. In some of these environments, all calls must be recorded for regulatory, compliance, and consumer-protection reasons. The recording of a session is typically performed by sending a copy of a media stream to a recording device. This document lists call flows with metadata snapshots sent from a Session Recording Client (SRC) to a Session Recording Server (SRS).
RFC8067 - Updating When Standards Track Documents May Refer Normatively to Documents at a Lower Level
RFC 3967 specifies a process for allowing normative references to documents at lower maturity levels ("downrefs"), which involves calling out the downref explicitly in the Last Call notice. That requirement has proven to be unnecessarily strict, and this document updates RFC 3967, allowing the IESG more flexibility in accepting downrefs in Standards Track documents.
RFC8066 - IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) ESC Dispatch Code Points and Guidelines
RFC 4944 defines the ESC dispatch type to allow additional dispatch octets in the 6LoWPAN header. The value of the ESC dispatch type was updated by RFC 6282; however, its usage was not defined in either RFC 6282 or RFC 4944. This document updates RFC 4944 and RFC 6282 by defining the ESC extension octet code points and listing registration entries for known use cases at the time of writing of this document.
RFC8065 - Privacy Considerations for IPv6 Adaptation-Layer Mechanisms
This document discusses how a number of privacy threats apply to technologies designed for IPv6 over various link-layer protocols, and it provides advice to protocol designers on how to address such threats in adaptation-layer specifications for IPv6 over such links.
RFC8064 - Recommendation on Stable IPv6 Interface Identifiers
This document changes the recommended default Interface Identifier (IID) generation scheme for cases where Stateless Address Autoconfiguration (SLAAC) is used to generate a stable IPv6 address. It recommends using the mechanism specified in RFC 7217 in such cases, and recommends against embedding stable link-layer addresses in IPv6 IIDs. It formally updates RFC 2464, RFC 2467, RFC 2470, RFC 2491, RFC 2492, RFC 2497, RFC 2590, RFC 3146, RFC 3572, RFC 4291, RFC 4338, RFC 4391, RFC 5072, and RFC 5121. This document does not change any existing recommendations concerning the use of temporary addresses as specified in RFC 4941.
RFC8063 - Key Relay Mapping for the Extensible Provisioning Protocol
This document describes an Extensible Provisioning Protocol (EPP) mapping for a key relay object that relays DNSSEC key material between EPP clients using the poll queue defined in RFC 5730.
RFC8062 - Anonymity Support for Kerberos
This document defines extensions to the Kerberos protocol to allow a Kerberos client to securely communicate with a Kerberos application service without revealing its identity, or without revealing more than its Kerberos realm. It also defines extensions that allow a Kerberos client to obtain anonymous credentials without revealing its identity to the Kerberos Key Distribution Center (KDC). This document updates RFCs 4120, 4121, and 4556. This document obsoletes RFC 6112 and reclassifies that document as Historic. RFC 6112 contained errors, and the protocol described in that specification is not interoperable with any known implementation. This specification describes a protocol that interoperates with multiple implementations.
RFC8061 - Locator/ID Separation Protocol (LISP) Data-Plane Confidentiality
This document describes a mechanism for encrypting traffic encapsulated using the Locator/ID Separation Protocol (LISP). The design describes how key exchange is achieved using existing LISP control-plane mechanisms as well as how to secure the LISP data plane from third-party surveillance attacks.
RFC8060 - LISP Canonical Address Format (LCAF)
This document defines a canonical address format encoding used in Locator/ID Separation Protocol (LISP) control messages and in the encoding of lookup keys for the LISP Mapping Database System.
RFC8059 - PIM Join Attributes for Locator/ID Separation Protocol (LISP) Environments
This document defines two PIM Join/Prune attributes that support the construction of multicast distribution trees where the root and receivers are located in different Locator/ID Separation Protocol (LISP) sites. These attributes allow the receiver site to select between unicast and multicast underlying transport and to convey the RLOC (Routing Locator) address of the receiver ETR (Egress Tunnel Router) to the control plane of the root ITR (Ingress Tunnel Router).
RFC8058 - Signaling One-Click Functionality for List Email Headers
This document describes a method for signaling a one-click function for the List-Unsubscribe email header field. The need for this arises out of the actuality that mail software sometimes fetches URLs in mail header fields, and thereby accidentally triggers unsubscriptions in the case of the List-Unsubscribe header field.
RFC8057 - Uniform Resource Name (URN) Namespaces for Broadband Forum
This document describes the Namespace Identifiers (NIDs) "bbf", "broadband-forum-org", and "dslforum-org" for Uniform Resource Names (URNs) used to identify resources published by Broadband Forum (BBF). BBF specifies and manages resources that utilize these three URN identification models. Management activities for these and other resource types are handled by BBF.
RFC8056 - Extensible Provisioning Protocol (EPP) and Registration Data Access Protocol (RDAP) Status Mapping
This document describes the mapping of the Extensible Provisioning Protocol (EPP) statuses with the statuses registered for use in the Registration Data Access Protocol (RDAP). This document identifies gaps in the mapping, and registers RDAP statuses to fill those gaps to ensure that all of the EPP statuses specified in RFCs are supported in RDAP.
RFC8055 - Session Initiation Protocol (SIP) Via Header Field Parameter to Indicate Received Realm
This specification defines a new Session Initiation Protocol (SIP) Via header field parameter, 'received-realm', which allows a SIP entity acting as an entry point to a transit network to indicate from which adjacent upstream network a SIP request is received by using a network realm value associated with the adjacent network.
RFC8054 - Network News Transfer Protocol (NNTP) Extension for Compression
This document defines an extension to the Network News Transport Protocol (NNTP) that allows a connection to be effectively and efficiently compressed between an NNTP client and server.
RFC8053 - HTTP Authentication Extensions for Interactive Clients
This document specifies extensions for the HTTP authentication framework for interactive clients. Currently, fundamental features of HTTP-level authentication are insufficient for complex requirements of various Web-based applications. This forces these applications to implement their own authentication frameworks by means such as HTML forms, which becomes one of the hurdles against introducing secure authentication mechanisms handled jointly by servers and user agents. The extended framework fills gaps between Web application requirements and HTTP authentication provisions to solve the above problems, while maintaining compatibility with existing Web and non-Web uses of HTTP authentication.
RFC8052 - Group Domain of Interpretation (GDOI) Protocol Support for IEC 62351 Security Services
The IEC 61850 power utility automation family of standards describes methods using Ethernet and IP for distributing control and data frames within and between substations. The IEC 61850-90-5 and IEC 62351-9 standards specify the use of the Group Domain of Interpretation (GDOI) protocol (RFC 6407) to distribute security transforms for some IEC 61850 security protocols. This memo defines GDOI payloads to support those security protocols.
RFC8051 - Applicability of a Stateful Path Computation Element (PCE)
A stateful Path Computation Element (PCE) maintains information about Label Switched Path (LSP) characteristics and resource usage within a network in order to provide traffic-engineering calculations for its associated Path Computation Clients (PCCs). This document describes general considerations for a stateful PCE deployment and examines its applicability and benefits, as well as its challenges and limitations, through a number of use cases. PCE Communication Protocol (PCEP) extensions required for stateful PCE usage are covered in separate documents.
RFC8050 - Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format with BGP Additional Path Extensions
This document extends the Multi-threaded Routing Toolkit (MRT) export format for Border Gateway Protocol (BGP) routing information by supporting the advertisement of multiple paths in BGP extensions.
RFC8049 - YANG Data Model for L3VPN Service Delivery
This document defines a YANG data model that can be used for communication between customers and network operators and to deliver a Layer 3 provider-provisioned VPN service. This document is limited to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364. This model is intended to be instantiated at the management system to deliver the overall service. It is not a configuration model to be used directly on network elements. This model provides an abstracted view of the Layer 3 IP VPN service configuration components. It will be up to the management system to take this model as input and use specific configuration models to configure the different network elements to deliver the service. How the configuration of network elements is done is out of scope for this document.
RFC8048 - 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). This document obsoletes RFC 7248.
RFC8047 - Host Multihoming with the Host Identity Protocol
This document defines host multihoming extensions to the Host Identity Protocol (HIP), by leveraging protocol components defined for host mobility.
RFC8046 - Host Mobility with the Host Identity Protocol
This document defines a mobility extension to the Host Identity Protocol (HIP). Specifically, this document defines a "LOCATOR_SET" parameter for HIP messages that allows for a HIP host to notify peers about alternate addresses at which it may be reached. This document also defines how the parameter can be used to preserve communications across a change to the IP address used by one or both peer hosts. The same LOCATOR_SET parameter can also be used to support end-host multihoming (as specified in RFC 8047). This document obsoletes RFC 5206.
RFC8045 - RADIUS Extensions for IP Port Configuration and Reporting
This document defines three new RADIUS attributes. For devices that implement IP port ranges, these attributes are used to communicate with a RADIUS server in order to configure and report IP transport ports as well as mapping behavior for specific hosts. This mechanism can be used in various deployment scenarios such as Carrier-Grade NAT, IPv4/IPv6 translators, Provider WLAN gateway, etc. This document defines a mapping between some RADIUS attributes and IP Flow Information Export (IPFIX) Information Element identifiers.
RFC8044 - Data Types in RADIUS
RADIUS specifications have used data types for two decades without defining them as managed entities. During this time, RADIUS implementations have named the data types and have used them in attribute definitions. This document updates the specifications to better follow established practice. We do this by naming the data types defined in RFC 6158, which have been used since at least the publication of RFC 2865. We provide an IANA registry for the data types and update the "RADIUS Attribute Types" registry to include a Data Type field for each attribute. Finally, we recommend that authors of RADIUS specifications use these types in preference to existing practice. This document updates RFCs 2865, 3162, 4072, 6158, 6572, and 7268.
RFC8043 - Source-Address-Dependent Routing and Source Address Selection for IPv6 Hosts: Overview of the Problem Space
This document presents the source-address-dependent routing (SADR) problem space from the host's perspective. Both multihomed hosts and hosts with multiple interfaces are considered. Several network architectures are presented to illustrate why source address selection and next-hop resolution are needed in view of source-address-dependent routing.
RFC8042 - OSPF Two-Part Metric
This document specifies an optional OSPF protocol extension to represent router metrics in a multi-access network in two parts: the metric from the router to the network and the metric from the network to the router. For such networks, the router-to-router metric for OSPF route computation is the sum of the two parts. This document updates RFC 2328.
RFC8041 - Use Cases and Operational Experience with Multipath TCP
This document discusses both use cases and operational experience with Multipath TCP (MPTCP) in real networks. It lists several prominent use cases where Multipath TCP has been considered and is being used. It also gives insight to some heuristics and decisions that have helped to realize these use cases and suggests possible improvements.
RFC8040 - RESTCONF Protocol
This document describes an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF).
RFC8039 - Multipath Time Synchronization
Clock synchronization protocols are very widely used in IP-based networks. The Network Time Protocol (NTP) has been commonly deployed for many years, and the last few years have seen an increasingly rapid deployment of the Precision Time Protocol (PTP). As time-sensitive applications evolve, clock accuracy requirements are becoming increasingly stringent, requiring the time synchronization protocols to provide high accuracy. This memo describes a multipath approach to PTP and NTP over IP networks, allowing the protocols to run concurrently over multiple communication paths between the master and slave clocks, without modifying these protocols. The multipath approach can significantly contribute to clock accuracy, security, and fault tolerance. The multipath approach that is presented in this document enables backward compatibility with nodes that do not support the multipath functionality.
RFC8038 - Exporting MIB Variables Using the IP Flow Information Export (IPFIX) Protocol
This document specifies a way to complement IP Flow Information Export (IPFIX) Data Records with Management Information Base (MIB) objects, avoiding the need to define new IPFIX Information Elements for existing MIB objects that are already fully specified.
RFC8037 - CFRG Elliptic Curve Diffie-Hellman (ECDH) and Signatures in JSON Object Signing and Encryption (JOSE)
This document defines how to use the Diffie-Hellman algorithms "X25519" and "X448" as well as the signature algorithms "Ed25519" and "Ed448" from the IRTF CFRG elliptic curves work in JSON Object Signing and Encryption (JOSE).

This document discusses the applicability of the Routing Protocol for Low-Power and Lossy Networks (RPL) in Advanced Metering Infrastructure (AMI) networks.
RFC8035 - Session Description Protocol (SDP) Offer/Answer Clarifications for RTP/RTCP Multiplexing
This document updates RFC 5761 by clarifying the SDP offer/answer negotiation of RTP and RTP Control Protocol (RTCP) multiplexing. It makes it clear that an answerer can only include an "a=rtcp-mux" attribute in a Session Description Protocol (SDP) answer if the associated SDP offer contained the attribute.
RFC8034 - Active Queue Management (AQM) Based on Proportional Integral Controller Enhanced (PIE) for Data-Over-Cable Service Interface Specifications (DOCSIS) Cable Modems
Cable modems based on Data-Over-Cable Service Interface Specifications (DOCSIS) provide broadband Internet access to over one hundred million users worldwide. In some cases, the cable modem connection is the bottleneck (lowest speed) link between the customer and the Internet. As a result, the impact of buffering and bufferbloat in the cable modem can have a significant effect on user experience. The CableLabs DOCSIS 3.1 specification introduces requirements for cable modems to support an Active Queue Management (AQM) algorithm that is intended to alleviate the impact that buffering has on latency-sensitive traffic, while preserving bulk throughput performance. In addition, the CableLabs DOCSIS 3.0 specifications have also been amended to contain similar requirements. This document describes the requirements on AQM that apply to DOCSIS equipment, including a description of the "DOCSIS-PIE" algorithm that is required on DOCSIS 3.1 cable modems.
RFC8033 - Proportional Integral Controller Enhanced (PIE): A Lightweight Control Scheme to Address the Bufferbloat Problem
Bufferbloat is a phenomenon in which excess buffers in the network cause high latency and latency variation. As more and more interactive applications (e.g., voice over IP, real-time video streaming, and financial transactions) run in the Internet, high latency and latency variation degrade application performance. There is a pressing need to design intelligent queue management schemes that can control latency and latency variation, and hence provide desirable quality of service to users.
RFC8032 - Edwards-Curve Digital Signature Algorithm (EdDSA)
This document describes elliptic curve signature scheme Edwards-curve Digital Signature Algorithm (EdDSA). The algorithm is instantiated with recommended parameters for the edwards25519 and edwards448 curves. An example implementation and test vectors are provided.
RFC8031 - Curve25519 and Curve448 for the Internet Key Exchange Protocol Version 2 (IKEv2) Key Agreement
This document describes the use of Curve25519 and Curve448 for ephemeral key exchange in the Internet Key Exchange Protocol Version 2 (IKEv2).
RFC8030 - Generic Event Delivery Using HTTP Push
This document describes a simple protocol for the delivery of real- time events to user agents. This scheme uses HTTP/2 server push.
SIP Back-to-Back User Agents (B2BUAs) are often designed to also be on the media path, rather than just to intercept signalling. This means that B2BUAs often implement an RTP or RTP Control Protocol (RTCP) stack as well, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP messages get lost because of mismatches in the reported data.

RFC8051 - Applicability of a Stateful Path Computation Element (PCE)
A stateful Path Computation Element (PCE) maintains information about Label Switched Path (LSP) characteristics and resource usage within a network in order to provide traffic-engineering calculations for its associated Path Computation Clients (PCCs). This document describes general considerations for a stateful PCE deployment and examines its applicability and benefits, as well as its challenges and limitations, through a number of use cases. PCE Communication Protocol (PCEP) extensions required for stateful PCE usage are covered in separate documents.
RFC8050 - Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format with BGP Additional Path Extensions
This document extends the Multi-threaded Routing Toolkit (MRT) export format for Border Gateway Protocol (BGP) routing information by supporting the advertisement of multiple paths in BGP extensions.
RFC8049 - YANG Data Model for L3VPN Service Delivery
This document defines a YANG data model that can be used for communication between customers and network operators and to deliver a Layer 3 provider-provisioned VPN service. This document is limited to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364. This model is intended to be instantiated at the management system to deliver the overall service. It is not a configuration model to be used directly on network elements. This model provides an abstracted view of the Layer 3 IP VPN service configuration components. It will be up to the management system to take this model as input and use specific configuration models to configure the different network elements to deliver the service. How the configuration of network elements is done is out of scope for this document.
RFC8048 - 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). This document obsoletes RFC 7248.
RFC8047 - Host Multihoming with the Host Identity Protocol
This document defines host multihoming extensions to the Host Identity Protocol (HIP), by leveraging protocol components defined for host mobility.
RFC8046 - Host Mobility with the Host Identity Protocol
This document defines a mobility extension to the Host Identity Protocol (HIP). Specifically, this document defines a "LOCATOR_SET" parameter for HIP messages that allows for a HIP host to notify peers about alternate addresses at which it may be reached. This document also defines how the parameter can be used to preserve communications across a change to the IP address used by one or both peer hosts. The same LOCATOR_SET parameter can also be used to support end-host multihoming (as specified in RFC 8047). This document obsoletes RFC 5206.
RFC8045 - RADIUS Extensions for IP Port Configuration and Reporting
This document defines three new RADIUS attributes. For devices that implement IP port ranges, these attributes are used to communicate with a RADIUS server in order to configure and report IP transport ports as well as mapping behavior for specific hosts. This mechanism can be used in various deployment scenarios such as Carrier-Grade NAT, IPv4/IPv6 translators, Provider WLAN gateway, etc. This document defines a mapping between some RADIUS attributes and IP Flow Information Export (IPFIX) Information Element identifiers.
RFC8044 - Data Types in RADIUS
RADIUS specifications have used data types for two decades without defining them as managed entities. During this time, RADIUS implementations have named the data types and have used them in attribute definitions. This document updates the specifications to better follow established practice. We do this by naming the data types defined in RFC 6158, which have been used since at least the publication of RFC 2865. We provide an IANA registry for the data types and update the "RADIUS Attribute Types" registry to include a Data Type field for each attribute. Finally, we recommend that authors of RADIUS specifications use these types in preference to existing practice. This document updates RFCs 2865, 3162, 4072, 6158, 6572, and 7268.
RFC8043 - Source-Address-Dependent Routing and Source Address Selection for IPv6 Hosts: Overview of the Problem Space
This document presents the source-address-dependent routing (SADR) problem space from the host's perspective. Both multihomed hosts and hosts with multiple interfaces are considered. Several network architectures are presented to illustrate why source address selection and next-hop resolution are needed in view of source-address-dependent routing.
RFC8042 - OSPF Two-Part Metric
This document specifies an optional OSPF protocol extension to represent router metrics in a multi-access network in two parts: the metric from the router to the network and the metric from the network to the router. For such networks, the router-to-router metric for OSPF route computation is the sum of the two parts. This document updates RFC 2328.
RFC8041 - Use Cases and Operational Experience with Multipath TCP
This document discusses both use cases and operational experience with Multipath TCP (MPTCP) in real networks. It lists several prominent use cases where Multipath TCP has been considered and is being used. It also gives insight to some heuristics and decisions that have helped to realize these use cases and suggests possible improvements.
RFC8040 - RESTCONF Protocol
This document describes an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF).
RFC8039 - Multipath Time Synchronization
Clock synchronization protocols are very widely used in IP-based networks. The Network Time Protocol (NTP) has been commonly deployed for many years, and the last few years have seen an increasingly rapid deployment of the Precision Time Protocol (PTP). As time-sensitive applications evolve, clock accuracy requirements are becoming increasingly stringent, requiring the time synchronization protocols to provide high accuracy. This memo describes a multipath approach to PTP and NTP over IP networks, allowing the protocols to run concurrently over multiple communication paths between the master and slave clocks, without modifying these protocols. The multipath approach can significantly contribute to clock accuracy, security, and fault tolerance. The multipath approach that is presented in this document enables backward compatibility with nodes that do not support the multipath functionality.
RFC8038 - Exporting MIB Variables Using the IP Flow Information Export (IPFIX) Protocol
This document specifies a way to complement IP Flow Information Export (IPFIX) Data Records with Management Information Base (MIB) objects, avoiding the need to define new IPFIX Information Elements for existing MIB objects that are already fully specified.
RFC8037 - CFRG Elliptic Curve Diffie-Hellman (ECDH) and Signatures in JSON Object Signing and Encryption (JOSE)
This document defines how to use the Diffie-Hellman algorithms "X25519" and "X448" as well as the signature algorithms "Ed25519" and "Ed448" from the IRTF CFRG elliptic curves work in JSON Object Signing and Encryption (JOSE).
RFC8036 - Applicability Statement for the Routing Protocol for Low-Power and Lossy Networks (RPL) in Advanced Metering Infrastructure (AMI) Networks
This document discusses the applicability of the Routing Protocol for Low-Power and Lossy Networks (RPL) in Advanced Metering Infrastructure (AMI) networks.
RFC8035 - Session Description Protocol (SDP) Offer/Answer Clarifications for RTP/RTCP Multiplexing
This document updates RFC 5761 by clarifying the SDP offer/answer negotiation of RTP and RTP Control Protocol (RTCP) multiplexing. It makes it clear that an answerer can only include an "a=rtcp-mux" attribute in a Session Description Protocol (SDP) answer if the associated SDP offer contained the attribute.
RFC8034 - Active Queue Management (AQM) Based on Proportional Integral Controller Enhanced (PIE) for Data-Over-Cable Service Interface Specifications (DOCSIS) Cable Modems
Cable modems based on Data-Over-Cable Service Interface Specifications (DOCSIS) provide broadband Internet access to over one hundred million users worldwide. In some cases, the cable modem connection is the bottleneck (lowest speed) link between the customer and the Internet. As a result, the impact of buffering and bufferbloat in the cable modem can have a significant effect on user experience. The CableLabs DOCSIS 3.1 specification introduces requirements for cable modems to support an Active Queue Management (AQM) algorithm that is intended to alleviate the impact that buffering has on latency-sensitive traffic, while preserving bulk throughput performance. In addition, the CableLabs DOCSIS 3.0 specifications have also been amended to contain similar requirements. This document describes the requirements on AQM that apply to DOCSIS equipment, including a description of the "DOCSIS-PIE" algorithm that is required on DOCSIS 3.1 cable modems.
RFC8033 - Proportional Integral Controller Enhanced (PIE): A Lightweight Control Scheme to Address the Bufferbloat Problem
Bufferbloat is a phenomenon in which excess buffers in the network cause high latency and latency variation. As more and more interactive applications (e.g., voice over IP, real-time video streaming, and financial transactions) run in the Internet, high latency and latency variation degrade application performance. There is a pressing need to design intelligent queue management schemes that can control latency and latency variation, and hence provide desirable quality of service to users.
RFC8032 - Edwards-Curve Digital Signature Algorithm (EdDSA)
This document describes elliptic curve signature scheme Edwards-curve Digital Signature Algorithm (EdDSA). The algorithm is instantiated with recommended parameters for the edwards25519 and edwards448 curves. An example implementation and test vectors are provided.
RFC8031 - Curve25519 and Curve448 for the Internet Key Exchange Protocol Version 2 (IKEv2) Key Agreement
This document describes the use of Curve25519 and Curve448 for ephemeral key exchange in the Internet Key Exchange Protocol Version 2 (IKEv2).
RFC8030 - Generic Event Delivery Using HTTP Push
This document describes a simple protocol for the delivery of real- time events to user agents. This scheme uses HTTP/2 server push.
