摘 要: 提出了一种在光网络节点中,通过设定可用资源的等级以及被锁定的时间来为呼叫和连接请求建立光链路的简单方法,可以实现3种具有服务等级光链路的建立;给出了网络节点的处理流程。通过在一个星形网络上的仿真分析和实验测试,验证了该方法的可行性。对于自动交换光网络中光链路的建立具有一定的参考意义。 Based on setting up the classification of the network usable resources and its locking time, a kind of simple distributed dynamic optical link establishment method with CoS (class of service) in automatic switching optical network was proposed. By this method, three kinds of optical link establishment with CoS can be realized. The proceeding scheme of the network node was also presented. Through simulation and experiment in a star wavelength router network, the method is verified and is useful for the optical link establishment in automatic switching optical network.
