Abstract :
Peer-to-peer SIP (P2PSIP) based server farm is proposed to provide distributed solution of multimedia applications. In this paper, we focus on the bandwidth requirements of both DHT and SIP packets from the perspective of a single server node in P2PSIP based server farm to quantitatively evaluate the overhead caused by distributed architecture. Furthermore, the efficiency of server node is also studied to reflect the extent to which the number of SIP messages that a single server node can deal with drops with the increasing size of the server farm. Simulation shows that although the bandwidth requirements of DHT packets take only a small portion of the total traffic, the efficiency of the server node is influenced significantly by the DHT architecture. Hence, the P2PSIP based server farm is a feasible alternative of implementation in real networks with the optimization requirements of efficiency.
