Title : REsource LOcation And Discovery (RELOAD)
Author(s) : D. Bryan, et al.
Filename : draft-bryan-p2psip-reload-01.txt
Pages : 56

This document outlines the motivation, requirements, and
architectural design for a extensible and lightweight distributed
REsource LOcation And Discovery (RELOAD) protocol. RELOAD is a Peer-
to-Peer (P2P) based approach for registration and resource discovery
using distributed hash tables maintained with binary messages. This
design removes the need for central servers from SIP, while offering
full backward compatibility with SIP, allowing reuse of existing
clients, and allowing P2P enabled peers to communicate with
conventional SIP entities. A basic introduction to the concepts of
P2P is presented, backward compatibility issues addressed, and
security considerations are discussed.
RELOAD is one possible implementation of the protocols being
discussed for creation in the P2PSIP WG. In the context of the work
being proposed, this draft represents a concrete proposal for the
P2PSIP Peer Protocol. RELOAD uses binary messages, derived as much
as possible from the STUN protocol, as the underlying protocol. Note
that in order to be as similar to STUN as possible, some text has
been re-used verbatim from I-Ds and RFCs describing STUN.
In this architecture, no P2PSIP Client Protocol is needed, rather
unmodified SIP is used for access by non-peers. This protocol
considers NAT traversal and fragmentation, supports storage of
information other than registrations, allows for multiple DHT and
hash algorithms, and provides hooks for multiple security schemes.
The protocol described here derives from a fully implemented and
commercially available system with running code.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
