| 摘 要： | 在给出波长路由环网模型的基础上，提出了一种新的整数线性规划公式以解决波长路由多纤环网（MFR）的优化设计问题，整数线性规划公式所采用的优化目标是最小结点端口数目，以此为优化目标可以保证所设计的多纤环网具有最大的经济性，利用所提出的整数线性规划公式，定量分析了在不同通信模式（单Hub和双Hub)，及路由方案（波长通道和虚波长通道）的情况下，单向和双向波长路由多纤环网的网络性能差异，所获得的结论有助于多纤环网结构的优化设计。

| Abstract: | Based on the wavelength routed ring network model, new integer linear programming (ILP) formulations were proposed to tackle the optimal design of wavelength routed multi fiber ring (MFR) networks. The optimal objective is to minimize the averaged node ports number. It can maximize the cost effectiveness of the disigned MFR networks. By using these algorithms, the difference of network performance between unidirectional and bidirectional multi fiber ring was analyzed quantitatively with the different traffic pattern (single hub and double hub) and routing schemes (wavelength path and virtual wavelength path). The obtained results are very useful for the optimal design of multi fiber ring networks. |
