大型IP网络中组播部署方案研究

近年来随着互联网用户数量的高速增长,网络多媒体应用的普及带来了IP网络带宽的急剧消耗,组播技术以其独特的优越性受到运营商的关注.然而,目前组播技术的使用仍然局限在少数小型网络中,组播部署缺少系统化、整体化的解决方案.本文介绍了一些关键的组播技术,在此基础上针对大型IP网络中的组播部署方案进行探讨,提出组播端到端的解决方案,并通过实验证明了该部署方案的可行性.

Multicasting Designing on Large IP Network

In these years, with rapid increase of Internet customers, popular network multimedia applications result in large usage of IP network bandwidth. Multicast technology draws attention of operators with special advantages. However, at present there are only few eases of multicast application on small networks. Design of multicast runs short of system and whole resolutions. This paper introduces some key multicast technologies. Then discusses deployment methods on large network and brings forward multicast end to end resolutions. At last, experiment results prove the feasibility.
