Title: "Large-Scale Internet Video Streaming: From P2P to Proxy-based Systems"

by

Mr. Dongni Ren


Abstract:

Peer-to-peer (P2P) technology has emerged as a promising scalable solu- 
tion to provide live streaming services to large groups. Compared to 
traditional simple unicast and content distribution networks (CDN), P2P 
streaming lever- ages the upload capacities of the peers so that the scale 
of the system is largely increased and the streaming cost (in terms of 
server bandwidth and computa- tional requirement) is signi cantly reduced. 
However, the performance of P2P live streaming is limited by problems such 
as peer churns, delay accumulation and asymmetric bandwidth of end hosts. 
In recent years, the use of proxies and sta- ble nodes are studied and a 
hybrid structure of proxy-based network augmented with P2P streaming are 
proposed in order to overcome many weaknesses of pure P2P design. 
Proxy-P2P systems achieve better performance in terms of delay, robustness 
and streaming e ciency. In this survey the state-of-art technologies and 
representative work from P2P live streaming to proxy-P2P systems are 
studied. Through discussing these work we try to uncover the major 
research challenges and opportunities in the area of Internet Streaming 
for future directions.
