摘 要:随着科学技术的不断发展,网络点播、视屏会议、远程课程等应用已经逐渐普及。然而薄弱的网络技术,已经无法适应技术的发展,组播技术应运而生。它有效解决了流量控制困难、服务器负载压力大等一系列问题。本文分为五个部分来对组播技术的应用进行研究:第一部分介绍了研究组播技术的背景和意义;第二部分介绍了组播技术的相关概念,它能够加快数据的传送速度,避免网络的拥塞[1];第三部分说明了组播技术的相关协议,主要有管理协议和路由协议;第四部分介绍了一个域内二、三层组播实验的配置和测试;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N 倍的带宽的使用长度[2]。

Abstract:With the continuous development of science and technology,the application of network on demand,video conferencing,distance courses and so on has been gradually popularized. But the weak network technology can not adapt to the development of technology until the emergence of multicast technology. It effectively solves a series of problems such as the difficulty of flow control and the high load pressure of servers. This paper is divided into five parts to study the application of multicast technology:the first part talks about the background and significance of multicast technology;the second part talks about the related concepts of multicast technology,which speeds up data transmission and avoids network congestion [1];the third part talks about the relevant protocols of multicast technology,mainly including management protocols and routing protocols;the fourth part introduces the configuration and testing of a two-tier and three-tier multicast experiment in the domain;the fifth part talks about network video conference based on multicast technology,multi-party network video conference,multicast can reduce N-times the bandwidth length [2].
