Taveira IST/INOV July 8, 2012 PPSP Tracker Protocol--Extended Protocol (PPSP-TP/1.1) draft-huang-ppsp-extended-tracker-protocol-00 Abstract This document specifies the extended Peer-to-Peer Streaming Protocol - Tracker Protocol (PPSP-TP/1.1), a new extension protocol complementing the basic core messages and usages specified in PPSP=TP/1.0 for the exchange of meta information between trackers and peers, such as initial offer/request of participation in multimedia content streaming, content information, peer lists and reports of activity and status. It extends PPSP-TP/1.0 to include new optional messages providing granular controls and usages in the communications between peer and tracker. The extension protocol is retro-compatible with PPSP-TP/1.0. Status of this Memo This Internet-Draft is submitted to IETF in full conformance with the provisions of BCP 78 and BCP 79.
