Multicast Grooming Algorithms in Waveband Switching Multi-Domain Optical Networks

摘要

In this paper, we study the multicast waveband grooming in multi-domain optical networks and propose three heuristic algorithms, Per-Domain Multicast Grooming (PDMG), Virtual Topology Multicast Grooming (VTMG) and Hierarchical Multi-domain Multicast Grooming (HMMG). Simulation results show that, comparing with PDMG and VTMG, HMMG has the best performance of ports savings and the lowest blocking probability.
