多目的IP传输设计实现

摘要

Multicast technique is often used in applications such as multimedia conference for its predominance in point to multi-point transmission.It is not widely used over intemet because of extending scope of using multicast routing is limited.This paper analyzes the working principle of multicast and brings forward the brief design of multi-destination transmission over IP which has character of multicast.Some key technologies are described.And then the design and implementation are explained in detail.%组播因其在点对多点传输方面拥有的优势,常被用于多媒体会议等应用.但是由于使用组播路由规模的限制,阻碍了在因特网推广组播技术的应用.首先对组播的原理作了分析,提出了具有组播特性的包含多个目的IP地址的IP传输设计,然后描述了一些关键问题,并讲解了具体设计和实现方法.
