RFC7878 - Session Peering Provisioning (SPP) Protocol over SOAP
The Session Peering Provisioning Framework (SPPF) specifies the data model and the overall structure to provision Session Establishment Data (SED) into Session Data Registries and SIP Service Provider data stores. To utilize this framework, one needs a substrate protocol. Given that the Simple Object Access Protocol (SOAP) is currently widely used for messaging between elements of such provisioning systems, this document specifies the usage of SOAP (via HTTPS) as the substrate protocol for SPPF. The benefits include leveraging prevalent expertise and a higher probability that existing provisioning systems will be able to easily migrate to using an \%SPPF- based protocol.
RFC7877 - Session Peering Provisioning Framework (SPPF)
This document specifies the data model and the overall structure for a framework to provision Session Establishment Data (SED) into Session Data Registries and SIP Service Provider (SSP) data stores. The framework is called the "Session Peering Provisioning Framework" (SPPF). The provisioned data is typically used by network elements for session establishment.
RFC7876 - UDP Return Path for Packet Loss and Delay Measurement for MPLS Networks

RFC7875 - Additional WebRTC Audio Codecs for Interoperability
To ensure a baseline of interoperability between WebRTC endpoints, a minimum set of required codecs is specified. However, to maximize the possibility of establishing the session without the need for audio transcoding, it is also recommended to include in the offer other suitable audio codecs that are available to the browser.
RFC7874 - WebRTC Audio Codec and Processing Requirements
This document outlines the audio codec and processing requirements for WebRTC endpoints.
RFC7873 - Domain Name System (DNS) Cookies
DNS Cookies are a lightweight DNS transaction security mechanism that provides limited protection to DNS servers and clients against a variety of increasingly common denial-of-service and amplification/ forgery or cache poisoning attacks by off-path attackers. DNS Cookies are tolerant of NAT, NAT-PT (Network Address Translation - Protocol Translation), and anycast and can be incrementally deployed. (Since DNS Cookies are only returned to the IP address from which they were originally received, they cannot be used to generally track Internet users.)
RFC7872 - Observations on the Dropping of Packets with IPv6 Extension Headers in the Real World
This document presents real-world data regarding the extent to which packets with IPv6 Extension Headers (EHs) are dropped in the Internet (as originally measured in August 2014 and later in June 2015, with similar results) and where in the network such dropping occurs. The aforementioned results serve as a problem statement that is expected to trigger operational advice on the filtering of IPv6 packets carrying IPv6 EHs so that the situation improves over time. This document also explains how the results were obtained, such that the corresponding measurements can be reproduced by other members of the community and repeated over time to observe changes in the handling of packets with IPv6 EHs.
RFC7871 - Client Subnet in DNS Queries
This document describes an Extension Mechanisms for DNS (EDNS0) option that is in active use to carry information about the network that originated a DNS query and the network for which the subsequent response can be cached. Since it has some known operational and privacy shortcomings, a revision will be worked through the IETF for improvement.

RFC7866 - Session Recording Protocol
This document specifies the use of the Session Initiation Protocol (SIP), the Session Description Protocol (SDP), and the Real-time Transport Protocol (RTP) for delivering real-time media and metadata from a Communication Session (CS) to a recording device. The Session Recording Protocol specifies the use of SIP, SDP, and RTP to establish a Recording Session (RS) between the Session Recording Client (SRC), which is on the path of the CS, and a Session Recording Server (SRS) at the recording device. This document considers only active recording, where the SRC purposefully streams media to an SRS and all participating user agents (UAs) are notified of the recording. Passive recording, where a recording device detects media directly from the network (e.g., using port-mirroring techniques), is outside the scope of this document. In addition, lawful intercept is outside the scope of this document.
RFC7865 - Session Initiation Protocol (SIP) Recording Metadata
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 describes the metadata model as viewed by the Session Recording Server (SRS) and the recording metadata format.
RFC7864 - Proxy Mobile IPv6 Extensions to Support Flow Mobility

RFC7856 - Softwire Mesh Management Information Base (MIB)
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for managing a softwire mesh.
RFC7855 - Source Packet Routing in Networking (SPRING) Problem Statement and Requirements
The ability for a node to specify a forwarding path, other than the normal shortest path, that a particular packet will traverse, benefits a number of network functions. Source-based routing mechanisms have previously been specified for network protocols but have not seen widespread adoption. In this context, the term "source" means "the point at which the explicit route is imposed"; therefore, it is not limited to the originator of the packet (i.e., the node imposing the explicit route may be the ingress node of an operator's network).
RFC7854 - BGP Monitoring Protocol (BMP)
This document defines the BGP Monitoring Protocol (BMP), which can be used to monitor BGP sessions. BMP is intended to provide a convenient interface for obtaining route views. Prior to the introduction of BMP, screen scraping was the most commonly used approach to obtaining such views. The design goals are to keep BMP simple, useful, easily implemented, and minimally service affecting. BMP is not suitable for use as a routing protocol.
RFC7853 - A URN Namespace for Globus
This document describes a URN (Uniform Resource Name) namespace to be used by Globus for naming persistent resources.
RFC7852 - Additional Data Related to an Emergency Call
When an emergency call is sent to a Public Safety Answering Point (PSAP), the originating device, the access network provider to which the device is connected, and all service providers in the path of the call have information about the call, the caller, or the location, which is helpful for the PSAP to have in handling the emergency. This document describes data structures and mechanisms to convey such data to the PSAP. The intent is that every emergency call carry as much of the information described here as possible using the mechanisms described here.
RFC7851 - Peer-to-Peer (P2P) Overlay Diagnostics
This document describes mechanisms for Peer-to-Peer (P2P) overlay diagnostics. It defines extensions to the REsource LOcation And Discovery (RELOAD) base protocol to collect diagnostic information and details the protocol specifications for these extensions. Useful diagnostic information for connection and node status monitoring is also defined. The document also describes the usage scenarios and provides examples of how these methods are used to perform diagnostics.

This document defines a profile that is a superset of the connections to IPv6 cellular networks defined in "IPv6 for Third Generation Partnership Project (3GPP) Cellular Hosts" (RFC 7066).
RFC7848 - Mark and Signed Mark Objects Mapping
Domain Name Registries (DNRs) may operate in special modes for certain periods of time, enabling trademark holders to protect their rights during the introduction of a Top-Level Domain (TLD).
RFC7847 - Logical-Interface Support for IP Hosts with Multi-Access Support
A logical interface is a software semantic internal to the host operating system. This semantic is available in all popular operating systems and is used in various protocol implementations. Logical-interface support is required on the mobile node attached to a Proxy Mobile IPv6 domain for leveraging various network-based mobility management features such as inter-technology handoffs, multihoming, and flow mobility support. This document explains the operational details of the logical-interface construct and the specifics on how link-layer implementations hide the physical interfaces from the IP stack and from the network nodes on the attached access networks. Furthermore, this document identifies the applicability of this approach to various link-layer technologies and analyzes the issues around it when used in conjunction with various mobility management features.
RFC7846 - Peer-to-Peer Streaming Tracker Protocol (PPSTP)
This document specifies the base Peer-to-Peer Streaming Tracker Protocol (PPSTP) version 1, an application-layer control (signaling) protocol for the exchange of meta information between trackers and peers. The specification outlines the architecture of the protocol and its functionality; it also describes message flows, message processing instructions, message formats, formal syntax, and semantics. The PPSTP enables cooperating peers to form content-streaming overlay networks to support near real-time delivery of structured media content (audio, video, and associated timed text and metadata), such as adaptive multi-rate, layered (scalable), and multi-view (3D) videos in live, time-shifted, and on-demand modes.
RFC7845 - Ogg Encapsulation for the Opus Audio Codec
This document defines the Ogg encapsulation for the Opus interactive speech and audio codec. This allows data encoded in the Opus format to be stored in an Ogg logical bitstream.
RFC7844 - Anonymity Profiles for DHCP Clients
Some DHCP options carry unique identifiers. These identifiers can enable device tracking even if the device administrator takes care of randomizing other potential identifications like link-layer addresses or IPv6 addresses. The anonymity profiles are designed for clients that wish to remain anonymous to the visited network. The profiles provide guidelines on the composition of DHCP or DHCPv6 messages, designed to minimize disclosure of identifying information.
RFC7843 - Port Control Protocol (PCP) Third-Party ID Option
This document describes a new Port Control Protocol (PCP) option called the THIRD_PARTY_ID option. It is designed to be used together with the THIRD_PARTY option specified in RFC 6887.

RFC7841 - RFC Streams, Headers, and Boilerplates
RFC documents contain a number of fixed elements such as the title page header, standard boilerplates, and copyright/IPR statements. This document describes them and introduces some updates to reflect current usage and requirements of RFC publication. In particular, this updated structure is intended to communicate clearly the source of RFC creation and review. This document obsoletes RFC 5741, moving detailed content to an IAB web page and preparing for more flexible output formats.
RFC7840 - A Routing Request Extension for the HTTP-Enabled Location Delivery (HELD) Protocol
For cases where location servers have access to emergency routing information, they are able to return routing information with the location information if the location request includes a request for the desired routing information. This document specifies an extension to the HTTP-Enabled Location Delivery (HELD) protocol that updates RFC 5985 to support this function. Allowing location and routing information to be acquired in a single request response exchange updates RFC 6881, as current location acquisition and route determination procedures are separate operations.
RFC7839 - Access-Network-Identifier Option in DHCP
This document specifies the format and mechanism that is to be used for encoding Access-Network Identifiers in DHCPv4 and DHCPv6 messages by defining new Access-Network-Identifier options and sub-options.
