基于资源占用最小化的计算通信联合虚拟网络映射方法
Computing Communication Joint Virtual Network Mapping Method Based on Resource Minimization
【摘要】 云计算数据中心整合了大量计算、存储及通信资源,已成为信息化时代的重要基础设施。传统纯有线数据中心网络拓扑固定,难以根据业务变化灵活调度网络资源,多采用配置冗余资源方式满足峰值业务资源需求,导致网络资源利用率偏低。在纯有线网络中引入无线链路,构建与通信业务分布相适配的动态网络拓扑,联合调度计算资源和有线/无线通信资源是提升网络资源利用率的有效方法。文章提出了基于资源占用最小化的计算通信联合虚拟网络映射方法,根据虚拟节点资源需求量整合或就近映射虚拟节点,以最小化通信资源占用率为目标,利用无线链路可灵活部署的特征,构建有线无线混合的映射网络路径。仿真结果证明该方法可有效提升虚拟网络请求的接收率和虚拟网络向物理网络映射的资源利用率。
【Abstract】 Cloud computing data centers integrate a large number of computing,storage and communication resources,and have become an important infrastructure in the information age.Traditional data center networks are characterized by fixed topology,which have difficulties in supporting flexible schedule network resource as the traffic changes.Besides,they usually over-provide network resource to meet the traffic demands in peak hours,resulting in low network resource utilization.It is an efficient way to improve network resource utilization by introducing wireless links into wired networks,constructing dynamic network topology adaptive to traffic distribution,and jointly scheduling computing resource and wired/wireless communication resource.A computing communication joint virtual network mapping method based on resource minimization is proposed in this paper,which maps virtual nodes integrally or closely according to their resource demands,targets at minimizing the network resource utilization,and constructs wired and wireless hybrid paths by using the flexible deployment features of wireless links.Simulation results prove that the method can effectively improve the acceptance rate of virtual network requests as well as the resource utilization when mapping virtual networks to physical networks.
