组播技术应用研究

摘要：在科学技术飞速发展的时代，网络点播、网络视频会议、远程课堂等应用在我们生活中越来越普及。然而，薄弱的网络科学技术，已经没有办法适应技术的发展。组播技术的应用，可以节省带宽，控制网络流量，减少了服务器和CPU负载，消除了流量的冗余，解决了多个接收者同时访问少数服务器资源时，服务器出现的一些问题。

本文分为五个部分：

第一部分，介绍了组播技术的研究背景和意义。

第二部分，介绍了组播的相关概念。它加快数据的传送速度，避免网络的拥塞[1]。

第三部分，介绍了组播的相关协议。分为组播成员的管理协议、路由的协议。组播的路由协议分为：域内的组播的路由的协议，域间的组播的路由的协议。

第四部分，做一个域内二、三层组播实验，并配置和测试。

第五部分，介绍了基于组播技术的网络视频会议。多方的网络视频会议，组播能降低A(N-1)倍的带宽的使用长度[2]。

Multicast Applied Research

Abstract: In the era of rapid development of science and technology, the network demand, network video conference, remote classroom and other applications in our lives more and more popular. However, a weak network of science and technology, has no way to adapt to technological developments. Application of multicast technology, can save bandwidth, control network traffic, reducing the server and CPU load, eliminating redundant traffic, to solve simultaneous access to multiple recipients few server resources, server problems occur.

This paper is divided into five parts:

The first part introduces the background and significance of multicast technology.

The second part introduces the concept of multicast. It accelerates data transfer rate to avoid network congestion [1].

The third part introduces the multicast related agreements. Members are divided into multicast management protocol, routing protocol. Multicast routing protocols are divided into: the domain multicast routing protocol, multicast inter-domain routing protocol.

The fourth part, do a domain two, three multicast test, and configuration and testing.

The fifth part introduces network based multicast video conferencing. Multi-network video conferencing, multicast can reduce A (N-1) times the bandwidth usage length [2].

Keywords: multicast; multicast protocols; within two, three multicast; video conference
