摘　　要：为解决光网络频谱分配服务执行次数低的问题,保证光网络频谱分配数据传输成功率最大化,提出基于改进蚁群算法的光网络频谱分配方案。考虑到频谱碎片化影响频谱分配效果,使用频谱重构方法进行碎片化频谱重构,考虑能量均衡构建光网络数据传输成功率最大化方法,继而构建光网络频谱分配目标函数,通过改进蚁群算法进行优化求解,最后得到分配方案。实验结果验证:本方法的光网络频谱业务数据传输成功率大于等于0.96,且降级服务执行次数相对最少,具有更高的应用价值。In order to solve the problem of low execution times of spectrum allocation service in optical network and ensure the maximum success rate of spectrum allocation data transmission in optical network,a spectrum allocation scheme based on improved ant colony algorithm is proposed.Considering that spectrum fragmentation affects the spectrum allocation effect,the spectrum reconstruction method is used to reconstruct the fragmented spectrum.Considering energy balance,the method to maximize the success rate of data transmission in optical network is constructed.Then the objective function of spectrum allocation in optical network is constructed.The optimization solution is obtained by improving ant colony algorithm.Finally,the allocation scheme is obtained.The experimental results show that the data transmission success rate of optical network spectrum services is greater than or equal to 0.96,and the number of degraded services is relatively minimum,which has higher application value.
