基于IP组播可靠传输协议的实现方案

组播提出的目的是为了减少对网络带宽的占用以节省通信成本,商业运用是推动组播技术发展的动力.但由于网络对IP组播数据报的传递是不安全的,所以组播走向商业应用必须解决可靠传输和通信安全的问题.为此探讨了在因特网上实现可靠组播技术的方案.;Multicast is a bandwidth-saving technology that reduces the cost of communication.Due to the benefits of multicast technology,multicast-based commercial applications become the main driving force for the development of the technology.But IP Multicast can not guarantee the reliability of data communication,which makes it necessary for multicast-based commercial applications to solve the security and reliability issues.Therefore,the solution of implementation of reliability multicast technology in Internet is discussed
