Paper Abstract

With the drastic increasing of data traffic, the optical transport network will be adjusted to be services-oriented networks. Its traffic engineering system should be able to dynamically react to traffic changes while at the same time fulfilling QoS requirements for different classes of service. So the next generation optical network will handle priority, preemption mechanisms, and traffic rerouting in order to concurrently accommodate the largest amount of traffic. At the same time, transport networks need to evolve so as to drastically reduce both deployment costs and operating expenses. One of a reasonable strategy to achieve the goals is to simplify the network architecture by reducing the number of layers. GMPLS protocols enable the coordination between the IP and the optical layers and provide classified services. The collaboration of both layers in the routing process leads to optimization of network performance. Simulation results show the results of different strategy for resource allocation.
