【摘要】：针对灵活栅格光网络中时变业务的路由和频谱分配问题,提出了面向流量均衡的最优最短路的路由和频谱分配算法。通过灵活的频谱扩展收缩策略指导频谱的分配,同时借助流量均衡的路由分配策略,使得网络中相邻的光通路在不同时刻共享部分频谱资源,以提高频谱的利用效率。
[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.
