Title

Providing Differentiated Qos For Peer-To-Peer File Sharing Systems

Abstract

In this paper, we propose a new Cluster Server Architecture (CSA) to realize an enhanced differentiated QoS in P2P file sharing systems. CSA adopts two approaches to provide a better QoS for dedicated users than standard users: (1) expedited forwarding messages of dedicated users and system maintenance messages at each node to speedup their response times, and (2) temporarily caching and instantly supplying routing information for dedicated users to reduce their self-organization overhead and warm-up time. Both theoretical analysis and simulation results show that our proposed architecture and algorithms effectively and efficiently implement a differentiated QoS model in P2P file sharing systems. The CSA introduces only modest overhead but still retains a good scalability and robustness.
