Design and implementation of a P2P media streaming simulation system based on scalable coded media

The scalable coded media can not only solve the network bandwidth adaptation,but also can enhance the resistance against the media streaming mistakes to some extent.A P2P media streaming simulation system based on the scalable coded media on opnet is presented.The overall architecture of the Peerfree system including its resources lookup mechanism and media streaming transportation mechanism,and the procedures of building the system are described in detail.The experiment results and the simulation analysis are given in the end.
