"Concepts and Terminology for Peer to Peer SIP", David Bryan, Philip Matthews, Eunsoo Shim, Dean Willis, Spencer Dawkins, 7-Jul-08. ( bytes)

This document defines concepts and terminology for use of 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 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 open problems being addressed by the P2PSIP working group. As this document matures, it is expected to define the general framework for P2PSIP.

"REsource LOcation And Discovery (RELOAD)", Cullen Jennings, Bruce Lowekamp, Eric Rescorla, Salman Baset, Henning Schulzrinne, 14-Jul-08. ( bytes)

This document defines REsource LOcation And Discovery (RELOAD), a peer-to-peer (P2P) signaling protocol for use on the Internet. A P2P signaling protocol provides its clients with an abstract storage and messaging service between a set of cooperating peers that form the overlay network. RELOAD is designed to support a P2P Session Initiation Protocol (P2PSIP) network, but can be utilized by other applications with similar requirements by defining new usages that specify the kinds of data that must be stored for a particular application. RELOAD defines a security model based on a certificate enrollment service that provides unique identities. NAT traversal is a fundamental service of the protocol. RELOAD also allows access from "client" nodes which do not need to route traffic or store data for others.

"A SIP Usage for RELOAD", Cullen Jennings, Bruce Lowekamp, Eric Rescorla, Salman Baset, Henning Schulzrinne, 27-Oct-08. ( bytes)

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. The SIP Usage provides lookup service for AoRs stored in the overlay. The SIP Usage also defines GRUUs that allow the registrations to map an AoR to a specific node reachable through the overlay. The Attach method is used to establish a direct connection between nodes through which SIP messages are exchanged.
