网络虚拟化技术作为变革网络体系的一种渐变式方案,分离了网络服务和物理基础设施,支持若干同构或异构的网络共享同一物理基础设施.它的管控架构主要解决虚拟网络与物理网络的映射关系、物理网络资源的切分和虚拟网络的部署等问题,直接关系到系统能否利用底层设备智能化地、快速地为租户提供网络资源的租赁服务.结合项目实施过程中网络虚拟化技术部署的实际需求,提出了2种管控架构模型,即全视图的管控架构和半视图的管控架构.实验结果表明,2种架构模型的性能指标存在差异,如部署时间、通信量和故障恢复时间等.
As a gradual change of network architecture, network virtualization technology separates the network service and physical infrastructure and supports several homogeneous or heterogeneous networks to share the same physical infrastructure. Its management and control architecture mainly solves the problems of virtual network and physical network The mapping between physical network resources and the deployment of virtual network issues directly related to the system can use the underlying equipment to provide intelligent and rapid rental of network resources for tenants.Combining with the project implementation process of network virtualization Two kinds of management and control architecture models are proposed, that is, full-view management control architecture and half-view control management architecture.The experimental results show that the performance indexes of the two kinds of architecture models are different, such as deployment time, traffic and fault recovery Time and so on.
