Abstract:

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 swiching(OBS )is chosen for burst and packet-oriented services;while optical circuit swiching(OCS)is chosen for the services requiring hinh bandwidth and guaranteed quality of service(Qos)Analyses and simulations show that the model is valid,and the performance of net-work can be improved

Key words: hybrid switched optical network;service-oriedted opticl network, optical burst swiching ;fiber delay line
