dc.description.abstract In an era of uncertain business tendencies, realizing profitable optical networks is emerging as the most urgent task for optical operators. This task is aggravated by the need to support quality of service (QoS) differentiation, especially with the continuous development of new applications, each having different QoS requirements. This letter proposes to tackle these challenges through the definition of a novel QoS-aware connection setup strategy. The proposed setup approach enables network operators to ensure both efficient utilization of network resources and connection blocking probability differentiation. Resource efficiency is achieved via event-driven rerouting, whereas differentiated blocking probability is realized by preemption. Specifically, high priority connections are equipped with the capability of preempting lower priority connections, which through event-driven rerouting experience smaller blocking probability. Performance of this novel connection setup strategy is analyzed in this letter by simulating its operation in the context of the National Science Foundation Network (NSFNET). The obtained simulation results show that the proposed strategy can minimize the overall blocking probability while achieving QoS differentiation. en_US
