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.
RFC7890 - Concepts and Terminology for Peer-to-Peer SIP (P2PSIP)
This document defines concepts and terminology for using the Session Initiation Protocol in a peer-to-peer environment where the traditional proxy-registrar and message-routing functions are replaced by a distributed mechanism. These mechanisms may be implemented using a Distributed Hash Table or other distributed data mechanism with similar external properties. This document includes a high-level view of the functional relationships between the network elements defined herein, a conceptual model of operations, and an outline of the related problems addressed by the P2PSIP working group, the REsource LOcation And Discovery (RELOAD) protocol, and the SIP usage document defined by the working group.
RFC7904 - A SIP Usage for REsource LOcation And Discovery (RELOAD)
This document defines a SIP Usage for REsource LOcation And Discovery (RELOAD). The SIP Usage provides the functionality of a SIP proxy or registrar in a fully distributed system and includes a lookup service for Address of Records (AORs) stored in the overlay. It also defines Globally Routable User Agent URIs (GRUUs) that allow the registrations to map an AOR to a specific node reachable through the overlay. After such initial contact of a Peer, the RELOAD AppAttach method is used to establish a direct connection between nodes through which SIP messages are exchanged.
