With the rising popularity of multicasting services in meshed wavelength division multiplexing (WDM) networks, protecting dynamic sub-wavelength granularity multicast requests against network failures becomes an important issue in network operation process. This paper investigates survivable dynamic multicast traffic grooming problem in WDM networks, and a connection-level segment shared protection...
With the rising popularity of multicast applications, various algorithms using either lightpath or light-tree schemes have been proposed for dynamic multicast traffic grooming in meshed wavelength division multiplexing (WDM) networks. To the best of our knowledge, however, no systematic comparison has ever been made betweenthe performanceofthe two schemesinminimizing network blocking probability....
