A dynamic traffic grooming algorithm based on holding time aware services

摘要

To solve the dynamic traffic grooming problems based on holding time aware services in the optical network, extensibility of residue lifetime, occupancy of resource and transmission delay are taken into consideration, the services model is built, and the high priority preemption for holding time aware services algorithm is proposed. Different grooming strategies are adopted for different service requirements. Minimizing loss of services algorithm is introduced to guarantee the QoS performance. The simulation proves that the block of low-grade services is sacrificed to guarantee the access of high-grade services, the real-time performance is improved, and the loss of traffic volume is decreased sharply.
