摘要
Use for reference of the great success of P2P in distributed file sharing and locating, by abolishing CDN central node and making all POP nodes, which adopt the cluster technique, being peers to each other, a distributed multimedia CDN model with P2P architecture is put forward. In order to implement the global load optimization, the two-level load balance algorithm based on network measurement is proposed. Files are sliced up and transmitted through P2P mechanism to satisfy the requirement on real time multi-media application and high quality of service. Results of analysis show us that this multimedia CDN model has better.expansibility, robustness, and quality of service.
