基于MPLS的IP组播在Linux环境下的设计与实现

Design and Implementation of IP multicast based on MPLS under the Linux environment

基于MPLS的IP组播是目前网络研究的热点问题之一,MPLS和IP组播技术的结合可以获得MPLS的高速率、QoS、流量工程、VPN和IP组播的带宽节省两方面的益处,MPLS和组播是两种互补的技术。在Linux环境下已经可以支持MPLS的单播技术,本文研究了在Linux单播环境下MPLS组播的一种扩展技术,介绍了其实现原理,关键技术,并给出了C语言的API。

IP Multicast technology based on MPLS Domain is a hot topic in Internet research.Merging MPLS and muhicast technologies can acquire two advantages：Muhicast saving bandwidth and MPLS supporting high-speed, QoS and traffic engineering, VPN.Muhicast and MPLSare two complementary technologies.In this paper,based on MPLS unicast technologies in Linux,studies muhieast extending,introduces its implementation principles,key technologies,and give C lauguage＇s user API.
