Abstract Considering both the survivability and traffic grooming, a differentiated shared protection algorithm using wavelength layered-graph called PSPTG, which means Partial Shared-path Protection algorithm supporting Traffic Grooming, is proposed. In this algorithm, a shared protection scheme of partial lightpath based on link reliability is presented to meet the requests of reliability and bandwidth of connections. Simulation results show that the algorithm is efficient in terms of resources utilization.
