Abstract :
The poor capacity limited and the single point of failure problem in SIP have been solved greatly by using P2P-SIP architecture. But call setup latency is still sensitive to searching delay. Our paper discusses the problem of call setup latency from other angle. We consider the P2P-SIP system´ performance to keep message transmitting without delay under the condition of number of super-node and ordinary-node varied, node´ access rate. We build a basic model and notation of lookup messages stream in P2P-SIP system. We analyze what is the key factors related and come to some conclusions and suggestion to design of P2P-SIP system.
