MPLS组播的改进应用研究

Study on the application of improving MPLS multicast application

介绍了IP组播传输的高效性和目前应用的局限性、MPLS技术的重要性和发展前景、MPLS组播技术的研究现状.通过在MPLS传输平台中引入合并组播的概念,提出了一种在MPLS组播中应用合并组播分布树(MPLSAMT)的算法,并举例说明在MPLS组播中采用MPLSAMT可有效减少组播路由器的路由表项.最后通过模拟验证:该算法的应用可以大大提高基于MPLS平台的骨干网的组播传输性能和效率.

Efficiency and current application limitations of IP Muhicast transmission, importance and development prospects of MPLS, and MPLS muhicast research are introduced. Through MPLS muhicast delivery platform, concept of the merger is introduced, and multicast application in the combined MPLS muhicast distribution tree （MPLSAMT） algorithm is put forward. Examples are given to illustrate the use of muhicast in MPLS can be effective in reducing MPLSAMT multicast routing item routing table. Finally, through simulation, the application of the algorithm can greatly enhance performance and efficiency of the platform based on MPLS rnulticast backbone network transmission.
