基于覆盖组播的应用层组通信服务系统

Service system in group communication based on overlay multicast

网络层组播是提供一对多或者多对多通信的最佳方式,但是由于其在技术上和非技术上的原因难以在Internet上部署。设计和实现了一种基于覆盖组播的组通信服务系统,为组通信应用提供组播服务。这个系统独立于路由器的组播机制,能够快速实现与应用系统的集成,而且能够利用多种传输协议,为构建基于Internet的组通信应用系统提供了有效的支持。

Although network layer multicast is the best way for one-to-one or one-to-many communication,it doesn＇t widely be deployedin the intemet. A group communication service system was designed and implemented based on overlay multicast for the application of the group communication. The system can support effectively the application of group communication owing to it possess a lot of characters to integrate rapidly with application, and doesn＇t depend on multicast on the router to utilize transport protocol ana so on.
