【摘要】：針對(duì)靈活柵格光網(wǎng)絡(luò)中時(shí)變業(yè)務(wù)的路由和頻譜分配問題,提出了面向流量均衡的最優(yōu)最短路的路由和頻譜分配算法。通過靈活的頻譜擴(kuò)展收縮策略指導(dǎo)頻譜的分配,同時(shí)借助流量均衡的路由分配策略,使得網(wǎng)絡(luò)中相鄰的光通路在不同時(shí)刻共享部分頻譜資源,以提高頻譜的利用效率。
[Abstract]:To solve the problem of routing and spectrum allocation for time-varying traffic in flexible grid optical networks, an optimal shortest path routing and spectrum allocation algorithm for traffic equalization is proposed. In order to improve the efficiency of spectrum utilization, the spectrum allocation is guided by a flexible spectrum spread contraction strategy, and the routing strategy of traffic balance is used to make the adjacent optical paths share some spectrum resources at different times in order to improve the efficiency of spectrum utilization.
