智能光网络技术和P2MP(点对多点)技术的融合将能够极大地促进光组播业务的发展。文章针对多层多域光网络中的P2MP业务,提出了一种 MDMPH(基于分层PCE(路径计算元素)的多域最小代价路径启发式)算法,并进行了仿真分析。与传统的PDB(基于逐域路径)算法、E-BRPC(基于扩展的反向回溯)算法以及 CTB(基于核心树)算法相比,MDMPH 算法能够计算出代价更小的P 2 MP路径树。

The conversing of intelligent optical networks with P2MP technology will greatly promote the development of optical multicast services.This paper proposes a hierarchical Path Calculation Element (PCE)-based Multi-Domain Minimum-cost Path Heuristic (MDMPH)algorithm and conducts the related simulation and analysis.Compared with the traditional Per-Do-main Based (PDB)algorithm,Extended-BRPC (E-BRPC)-based algorithm and Core Tree Based (CTB)algorithm,MDMPH algorithm can calculate a smaller cost P2MP path tree.
