英文摘要：

Due to the lack consideration of general and scalability in the existing simulators of Peer-to-Peer-Video-on-Demand（P2P-VoD） systems based on network coding, a general simulation platform based on NS2 is proposed. The network coding mechanism is extended on the basis of NS2. The Socket model and interface model are designed to provide P2P application. To complete the simulation platform, the P2P-VoD application models are designed and devcloped. Simulation results show that the data scheduling algorithm based on network coding can be simulated effectively with the proposed platform and the platform possesses general and scalability.
