混合光交换网络中的一种条件汇聚机制

Constrained assembly scheme in hybrid optical switching networks

提出了一种新的混合光交换网络模型及节点结构,并在此模型结构下,针对长时低速业务流,给出了一种条件汇聚机制。该汇聚机制能根据业务流的到达状况,动态采用不同交换模式,从而提高了网络资源的利用率。仿真结果表明该汇聚机制能提高链路带宽利用率,从而提高网络的吞吐率。

In this essay, a new hybrid optical switching network model and node architecture are proposed. Under this model, a constrained assembly scheme for the long duration and low speed flow is presented. According to the arrival of the traffic flow, the switching module can be dynamically reconfigured and then the network resource utilization would be improved. The simulation result indicates that the proposed assembly ratio and improve the network throughput. scheme could raise the link bandwidth utilization ratio and improve the network throughput.
