摘要:

路由与波长分配是全光网络重要的资源分配方法。针对传统方法与新架构结合的问题,提出了一种基于SDN的自适应多目标路由与波长分配方法,能够通过自我调节的方式实现全光网络的链路资源调配。该方法基于SDN服务功能链模式,以调度时间和链路质量为调度目标,将路由与波长分配问题构建为0-1整数规划问题,同时采用二进制混合拓扑粒子群算法对该模型求解实现网络资源的优化调度。仿真实验结果表明,所提方法在恢复时间、阻塞率、资源利用率等指标的测试中均优于传统经典算法的性能。

Abstract:

Routing and wavelength assignment is an important resource allocation method of all-optical network.Aiming at the problem of traditional method combined with the new architecture,an adaptive multi-objective routing and wavelength assignment method based on SDN was proposed,which could realize the allocation of link resources of all-optical network through self-regulation.Based on the SDN service function chain model,service scheduling time and link service quality were taken as the scheduling objective,routing and wavelength assignment problem was constructed as the 0-1 integer programming problem,meanwhile,binary hybrid topology particle swarm optimization algorithm was used to optimize the network resources for optimal scheduling.The simulation results show that the proposed method is superior to the traditional classical algorithms in the test of recovery time,blocking rate and resource utilization.

Key words: software defined network, all-optical network, routing and wavelength assignment, service function chaining
