PPSP Tracker Protocol-Extended Protocol
draft-huang-ppsp-extended-tracker-protocol-06
Abstract
This document specifies an extension to the PPSP Tracker Protocol -
Base Protocol, which complements the core messages of the protocol
with Request-Response enhancements and usages, and with a new
DISCONNECT Protocol-level message. These enhancements and usages are
related with the exchange of meta information between trackers and
peers, such as initial offer/request of participation in multimedia
content streaming, content information, peer lists, reports of
activity and status, and graceful disconnection from the network.
The extension is retro-compatible with the PPSP-TP Base Protocol.
