Peer-to-Peer Epi-Transport Protocol

University of Udine

The DSP group at the University of Udine is developing PPETP (Peer-to-Peer Epi-Transport Protocol), a new streaming protocol based on a peer-to-peer approach that will allow to distribute efficiently live multimedia material to a large number of users.  Initially aimed to the specific application of multimedia streaming, the protocol evolved with time and now it can be considered a general-purpose overlay multicast protocol with many features (e.g., efficient use of bandwidth, NAT-traversal built-in procedures, countermeasures against security issues specific to peer-to-peer networks) that make it suitable for efficient multimedia streaming.
