— The paper proposes a novel SLA-aware mechanism to improve the performance of the networks with huge traffic volume of high priority connection requests with long holding time for optical shared mesh networks. The proposed mechanism consists of two parts, a novel reprovisioning algorithm which buffers and further processes the potentially blocked high priority connection requests, and a new time-aware path constraint which takes advantage of availability and holding-time as two crucial SLA connection parameters. The proposed mechanism benefits from dynamic service level agreement negotiation between a customer and service providers. The simulation results show reduced blocking probability, increased availability satisfaction rate, decreased resource overbuild, and better resource utilization to preserve the high priority class of traffic compared to other SLA-aware algorithms and protection schemes in shared mesh optical networks.
