Executive Summary

Streaming high quality videos consumes significantly large amount of network resources. In this paper request-to-service delay, network traffic, congestion and server overloading are the main parameters to be considered in video streaming over the internet that effect the Quality of Service (QoS). In this paper, the authors propose an efficient architecture as a cluster of proxy servers and clients that uses a Peer-To-Peer (P2P) approach to cooperatively stream the video using chaining technique. They consider the following two key issues in the proposed architecture Prefix caching technique to accommodate more number of videos close to client Cooperative client and proxy chaining to achieve the network efficiency.
