【摘要】 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．更多还原

【Abstract】 This paper considers the problem of designing a wavelength routed multihop optical network with wavelength continuity constraint It is formulated it as a mixed integer linear programming (MILP) problem The objective function is to minimize the number of average packet hops It is taken six node bidirectional ring network and mesh network as examples For different network architecture parameters,e g the number of transceivers and wavelengths,the optimal performances of network with and without wavelength continuity constraint are compared The numerical results show that the effect of wavelength continuity constraint on network performance is negligible in small scale multihop optical network更多还原
