An effective RSA scheme under the consideration of diffserv QoS in multi-domain heterogeneous software defined optical network

摘要

In this paper, for the purpose of supporting an end-to-end business process with guaranteeing the quality of transmission (QoT) of signal in multi-domain heterogeneous software defined optical networks, we emphatically design routing and spectrum assignment (RSA) algorithm to establish optical paths and allocate spectrum resources. The simulation results verified that compared with distributed scheme, the proposed algorithm can reduce overall network blocking probability.
