MPLS VPN组播的研究与仿真

Research and Simulation on MPLS VPN Multicast

对MPLSVPN特有的组播问题进行了分析和研究,比较了现有各种组播实现方案的优缺点。在此基础上,提出了一种改进的MPLSVPN组播实现方法——组播域显式组播路由法。最后进行了仿真,验证了改进方案的可行性、实用性和优越性。

This paper presents the research on the muhicast problem special to MPLS VPN network and compares the advantages and disadvantages of the existing multicast schemes. Based on this, an improved method, Multicast Domain Explicit Multicast Router, is provided. The scheme is implemented using OPNET, and the feasibility, practicability and advantages of the improved scheme are validated.
