本文研究了具有波长连续性限制的波长路由多跳光网的设计问题，并将其归结为混合整数线性规划问题．它的目标函数是最小化平均分组跳数目．我们分别以６个结点的双向环网和格状网为例．对于不同的网络结构参数（例如收发机数目和波长数目），比较了具有和不具有波长连续性限制的网络性能．数值结果表明在小规模波长路由多跳光网中波长连续性限制对网络性能的影响是可以忽略的． In this paper, the design of wavelength-routed multi-hop optical networks with wavelength continuity constraints is studied, and it is reduced to a mixed-integer linear programming problem. Its objective function is to minimize the average number of packet hops. We take the six nodes of the two-way ring network and mesh network as an example. For different network structure parameters (such as the number of transceivers and the number of wavelengths), network performance with and without wavelength continuity constraints is compared. The numerical results show that the effect of wavelength continuity restriction on network performance in multi-hop optical networks with small-scale wavelength routing is negligible.
