                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.
