Li Wei, Jin Xin, Yang Bo, et al. Hierarchical PCE-based multi-domain minimum-cost path heuristic algorithm. [J]. (6):19-21(2014) DOI: 10.13756/j.gtxyj.2014.06.005.
The conversing of intelligent optical networks with P2 MP 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-Domain Based(PDB)algorithm
Extended-BRPC(E-BRPC)-based algorithm and Core Tree Based(CTB)algorithm
MDMPH algorithm can calculate a smaller cost P2 MP path tree.
