摘要
Survivable Multicast Traffic Grooming (SMTG) is a promising approach to provide reliable and resource-efficient multi-granularity multicast services in mesh Wavelength-Division Multiplexing (WDM) optical networks. In this paper, we focus on the problem of SMTG in WDM mesh networks and propose two models, named Traffic Grooming with Shared Protection (TG-SP) and Traffic Grooming with Mixed Band Protection (TG-MBP) respectively. Basing on the two models, we present two algorithms, named Multicast Traffic Grooming with Segment Protection (MTG-SP) and Multicast Traffic Grooming with Shared Segment Protection (MTG-SSP) respectively. From the simulation results, we can see that MTG-SSP algorithm has better performance than MTG-SP algorithm at the cost of higher computation complexity.
