| 摘 要： | 针对VoD系统节目点播的不均匀特性以及P2P系统的动态变化特性，设计了一种多层次的网络拓扑组织结构，包括：链网状结构、基于服务频道的块状分群结构、以及DHT查询存储结构，以保证不同点播频率的节目都能获得较好的QoS保证。仿真结果表明，这种多层次的系统结构可以有效地保证用户的QoS需求。

| Abstract: | To resolve the asymmetry request problems of VoD programs and to adapt structures to the dynamic characteristics of P2P networks,a new network framework with multiple levels is designed,which includes a chain-mesh structure,a block-clustered structure based on serving-channel,and a DHT-based lookup-storage structure.It ensures that the system can provide QoS guarantees for programs with different order probability.Simulation results show that this kind of structure is effective,and the quanlity of service i... |
