现有网络需要同时支持电路和分组业务,使用1个交换平面同时转发2种业务有利于设备的共享和网络的融合.针对该需求,在Clos交换网络的基础上提出了电路与分组的混合交换网络及调度机制.在混合交换网络中,调度机制为电路业务分配专用通路,同时利用剩余带宽为分组业务提供尽力而为的转发服务.仿真结果表明,混合交换可以满足电路业务对服务质量的要求,并可以为分组业务提供较高的吞吐率.
The existing network needs to support both circuit and packet services at the same time, and the use of one switching plane to forward two services at the same time is beneficial to the sharing of devices and the convergence of the network.According to this requirement, a hybrid exchange of circuits and packets is proposed on the basis of the Clos switching network Network and scheduling mechanism.In the hybrid switching network, the scheduling mechanism allocates a dedicated path for the circuit services and utilizes the remaining bandwidth to provide the best-effort forwarding service for the packet services.The simulation results show that the hybrid switching can meet the requirements of the circuit services for the service quality , And can provide higher throughput for packet services.
