Abstract Most of Peer-to-Peer survey papers are described about the P2P applications architecture. It is hard to compare PPSP with them with the high-level description. In this survey, we focus on the message design for the well-known P2P file downloading and streaming applications (Bittorrent and eMule) and study their base and enhancement approach in the peer and tracker protocol specifications. Through the survey, we summarize a common message design for the P2P streaming Protocol standardization. Wu, et al.

Section 2 lists the terminology used. Section 3 describes the P2P file downloading protocols. Section 4 describes the P2P streaming protocols. Section 5 discusses the open issues. Section 6 summarizes a common protocol description for P2P streaming protocols standardization. Wu, et al. Expires April 18, 2011 [Page 3] Internet-Draft P2P Layered Streaming October 2010 2.
