Peer-to-Peer Live Streaming"

Abstract

Peer-to-peer (P2P) technology has emerged as a promising scalable solution 
for live streaming to a large group. In this thesis, we address the design 
of an overlay mesh which achieves low source-to-peer delay, accommodates 
asymmetric and diverse uplink bandwidth, and continuously improves delay 
based on an existing pool of peers. By considering a streaming mesh as an 
aggregation of data flows along multiple spanning trees, the peer delay in 
the mesh is then its longest delay (including both propagation and 
scheduling delay) among all the trees. Clearly, such delay can be very 
high if the mesh is not designed well. In this thesis we propose and study 
a mesh protocol called Fast-Mesh, which optimizes such delay while meeting 
a certain streaming bandwidth requirement. Fast-Mesh is particularly 
suitable for a mildly dynamic network consisting of proxies, supernodes, 
or content distribution servers.
