多层次周期性广播策略及其资源分配

Hierarchical periodic broadcasting stratagem and resource allocation

提出了一种具有良好可扩展性的异步视频传输模型 :在网络层基于下一代高速互联网络将广泛支持的组播技术 ,在应用层创造性地使用了多层次的周期性广播策略 .从而较为有效地解决了在分布式多视频服务器环境下系统提供异步视频服务的性能。

An asynchronous video streaming model with good scalability is discussed in this paper, which is based on multicast in the network layer and uses hierarchical periodic broadcasting stratagem in application layer. The performance, cost and scalability problems of video services under distributed multi video servers environment are solved effectively with this model.
