Technical Summary:
This document defines concepts and terminology for the 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.  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 and the RELOAD protocol [RFC6940] and SIP usage. 

Working Group Summary:
This document has had a relatively long gestation period in the working group, and it fact languished for several years.  After development of the protocol and other documents, it was felt that completing the concepts document would be helpful for readers of the protocol and other documents to understand the basic concepts behind the protocol.  As  result, this document was updated to reflect the evolution of the various documents and it now reflects the documented state of the protocol.  There were no notable disagreements within the working group over the development of the document.  

Document Quality:
The document was written by one of the original contributors to the entire p2psip effort, and has benefitted from review of the more active workgroup’s participants.  I believe it accurately reflects the concepts behind the RELOAD protocol.
