| 摘 要： | 采用整数线性规划算法和启发式算法对均匀和非均匀业务模式下WDM(Wavelength Division Multiplexing)网络的业务疏导问题进行研究,优化目标为最小化给定业务矩阵情况下所需光收发机和波长数。以环网为例进行了数值仿真,数值结果验证了启发式算法的有效性,并表明随着环网规模的增大,通过疏导减少的光通道数越来越大,疏导的效果也越来越明显。

| Abstract: | To investigate the problem of traffic grooming in WDM optical networks for both uniform and non-uniform traffic patterns,an ILP(Interger Linear Programming) algorithm and a heuristic algorithm are presented.The optimization objective of traffic grooming is to minimize the number of optical transceivers and wavelengths for a given traffic matrix.Taking WDM rings as examples,numerical results derived verify the effectiveness of the heuristic algorithm.It also demonstrates that the bigger the scale of ring net... |
