Request response scheme on server for the centralized P2P-VoD system

Abstract

Peer-to-Peer(P2P)-based Video-on-Demand application has gained more attentions recently. Due to the system complexity, there are still many challenges for practical deployment such as peer selection. Previous works focused on how to find the most suitable service or the request response scheme on the peer-side. In this paper, we study the request response scheme on the server-side by discussing three kinds of response schemes, e.g. urgency first (UF), fresh request first (FRF) and complemental request first (RCF). Besides that, we proposed a redirection scheme named server request redirection (SRR) to improve the quality of service (QoS) of P2P-VoD system further, which is verified by the simulation results.
