支持卫星信息分发的并行多点传输

Parallel Multi-point Transmission to Support Satellite Information Distribution

为了给卫星信息提供灵活、高效率、可扩展的分发服务,系统采用并行多点传输技术.将所有参与分发的节点组织为P2P网络,系统中每个节点都是对等的;在参与分发节点的选择上,采用一种基于节点簇和响应时间的节点选择策略,选择响应速度快、服务性能好的节点.力争通过对并行多点传输的优化,使卫星信息的分发更有效.

In order to provide flexible, efficient, scalable distribution services for Satellite information, parallel multi - point transmission technology is used. All those peers involved in the distribution are organized to P2P networks. Any client peers with part of the contents can offer external download service. The peer selection strategy based on peer clusters and response time is used to choose the participating in distributing peer, in order to save the system resources and raise the downloading speed Through the optimization of parallel multi -spot transmission, as far as possible, the satellite information distribution system is more effective.
