A Real-Data-Stimulated Simulation Assessment Method for P2P-Assisted Telecom IPTV Systems

With China Telecom IPTV system rapidly expanding, reducing operating and deployment costs has become an important issue. To improve IPTV transmission efficiency, using P2P technology is one of the possible solutions. This paper presents a new real-data-stimulated simulation assessment method for P2P-assisted telecom IPTV systems. The new method first proposes a set of performance metrics and primitives to evaluate the system, secondly it analyzes the real topology and actual user behaviors of Shanghai Telecom IPTV system, thirdly it builds a large-scale simulation system RVSPS, and stimulates the simulation system with real topology and actual user behaviors, then it analyzes the impact that various primitives have on the performance metrics. The simulation results show that this method can effectively evaluate the performance of the P2P-assisted telecom IPTV system.
