| 摘 要： | 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.

| Abstract: | Both circuit and packet traffics are supported in present communication networks. Forwarding those two traffics over the same switching fabric favors the sharing of network devices and the integration of networks. A combined circuit/packet switching fabric and dispatching scheme was proposed based on Clos-network switches. Dedicated paths were reserved for circuit traffic by dispatching scheme in the switching fabric. Meanwhile the remaining bandwidth is used to provide packet traffic with best-effort forwarding. Simulation shows that quality of service requirement of circuit traffic is satisfied, and a high throughput is achieved for packet traffic. |
