Abstract: Aiming at the problem of the high complexities and port contentions of current routing switching mechanism, this paper proposes a dynamic re-routing switching mechanism based on Combined Input and Crosspoint Queuing(CICQ) switching fabric. It maintains multiple optional output port in forwarding layer according to the topology of the internet for each reachable destination, implements re-routing internal the switches according to congestion status to achieve real-time load balancing. Simulation results show that network switching system with this mechanism can provide good performance.

Key words: switching fabric, Combined Input and Crosspoint Queuing(CICQ), dynamic re-routing

摘要： 针对现有路由交换机制存在计算复杂度过高以及端口争用问题，提出基于联合输入交叉节点排队交换结构的动态重路由交换机制。该机制依据互联网在路由拓扑层的路径多样化特点，在转发层为每个分组维护多个可选输出端口，并根据交换系统拥塞度实施分组动态重路由，从而实现网络流量的实时动态均衡。仿真结果表明，以该机制为构件的网络交换系统能获得良好的性能保障。
