Survivable Traffic Grooming Routing and Spectrum Assignment in Flex Grid Optical Network under Dynamic Multicast Traffic
Flex grid optical networks provide flexible grid architecture and elastic assignment of spectral resources, unlike fixed grid optical networks. The two prime objectives in this domain are to efficiently use spectral resources and to provide suitable protection against link failures which would cause a huge loss of data. In this study, we propose a heuristic approach to solve the traffic grooming problem integrated with survivability problem under dynamic traffic scenario. The traffic demands are multicast so they are routed through a light tree. The proposed approach performs better than state of the art approach concerning blocking probability and bandwidth blocking probability.
