面向业务的混合交换光网络模型评估

Performance Evaluation of Service-Oriented Hybrid Switched Optical Networks

为了结合光突发交换和光电路交换的优势,设计了一种基于业务平面对不同交换方式自适应的混合交换光网络模型,业务平面根据业务类型选择不同的交换方式,提高了光网络的自适应能力,从而提高网络的资源利用率.仿真结果验证了理论模型的正确性和有效性.

A hybrid switched optical network based on service plane is proposed for improving the adaptability of optical network. Service plane can choose different switch mode according with service type. Optical burst switching （OBS） is chosen for burst and packet-oriented services; while optical cir-cuit switching （OCS） is chosen for the services requiring high bandwidth and guaranteed quality of service （QoS） . Analyses and simulation results show that the model is valid, and the performance of net-work can be improved.
