Logical topologies design of wavelength-routed ring networks based on minimizing average packet hops

本文提出了用混合整数线性规则 (MILP)进行波长路由环网的逻辑拓扑设计。对于给定的通信流量矩阵 ,其目标函数是最小化平均分组跳。以双向环网为例 ,对于不同网络结构参数的情况 ,进行了计算分析并给出了数值结果。

In this paper,we proposed that the logical topology design of wavelength routed ring network using mixed integer linear programming(MILP) For a given traffic demand matrix,the objective function of this optimal problem is to minimize the average packet hop distance We take the bidirectional ring network as an example For different network architecture parameters,the numerical results and analyses were provided In addition,we also compare the case of unidirectional ring network with bidirectional ring network
