在流媒体系统的服务质量参数中，实时响应和平滑播放是很重要的参数。以P2P网络作为流媒体系统的运行支撑环境，充分运用该网络结构中对等节点的计算资源和带宽资源。P2P结构的动态性决定流媒体系统不能给用户提供一种稳定的高质量服务，所以需要在P2P网络层和流媒体系统应用层中间部署一种多通道信息服务层，该层屏蔽P2P网络的动态性。另外，该信息服务层从多对等节点并行向上层流媒体系统提供资源传输，并且各并行节点上缓存一部分媒体数据，从而提高了服务节点对请求客户节点的响应实时性。该信息服务模型是一种树形结构，可提供高效的查询服务。

The import parameters are responding real time and playing back smoothly in the service param-eters of the streaming system. This system uses P2P network as working environment of the streaming system so that the compute and bandwidth resource of the peer node of network framework are utilized fully. The streaming system can't provide steady high quality service be-cause of the dynamic of P2P network framework, so the multi-channel service layer is deployed between the streaming system application layer and P2P network layer. The dynamic is screened by the multi-channel service layer. In addition, the peer node provides parallel resource trans-mission to the streaming system layer in the information service layer. Because a part streaming data is cached in the peer node, increases the responding real time that the service node provide service to the request node with. The information service model can provide high efficiency query service.
