Preemption-Enabled Setup of Optical Connections Coupled With Event-Driven Rerouting

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 paper 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.
