摘要/Abstract

摘要： 为解决弹性光网络中虚拟网络映射时能耗严重、资源分配不均的问题，该文提出一种联合能耗与负载均衡的虚拟网络映射（PC-LB-VONE）方法.在虚拟节点映射时，选择相邻链路长度短、光节点计算资源多与相邻链路带宽资源多的光节点映射.在虚拟链路映射时，提出一种基于极大团的候选光路资源匹配度单路径映射策略.当单路径映射失败时，设计基于链路负载均值的多路径映射策略.仿真结果表明，所提方法能在减少弹性光网络能耗的同时均衡网络负载.

关键词: 弹性光网络, 虚拟网络, 极大团, 资源匹配度, 能耗, 负载均衡

Abstract: Due to the energy consumption and imbalance resources allocation in virtual optical network embedding over elastic optical networks,a joint power consumption and load balancing for virtual optical network embedding (PC-LB-VONE) is proposed.During virtual node embedding,we select the physical node which has shorter length of its adjacent link,and smaller difference between its computing resources and bandwidth resources of its adjacent link.During virtual link embedding,considering the resource matching degree of candidate optical paths,a single-path embedding strategy based on maximal clique is proposed.When the single-path embedding strategy fails,a multi-path embedding strategy based on the average link load will be taken.Simulation results show that the proposed PC-LB-VONE algorithm can effectively decrease the energy consumption and balance the traffic load.

Key words: elastic optical networks, virtual network, maximal clique, resource matching degree, power consumption, load balance
