A Traffic Grooming Algorithm based on Shared Protection in WDM mesh networks

摘要：

In WDM networks, the bandwidth request of a traffic stream is usually much lower than the capacity of a wavelength. Traffic grooming can aggregate low-rate connections onto high-capacity lightpaths to make efficient use of the bandwidth. But most of the researches related to traffic grooming focused on ring networks, and fewer concerns are about the dependable traffic grooming of low-rate connections in WDM mesh networks. In our study,we present a Shared Protection Traffic Grooming algorithm based on wavelength layered-graph (SPTG-LG) considering both the survivability and traffic grooming in WDM mesh networks. Some simulations and analysis are also given out.
