摘要:
为了保障虚拟路由器控制平面链路带宽资源的公平性以及流量隔离，本文在Linux系统上设计并实现了虚拟控制平面实例与逻辑转发引擎间的通信中间层——VNETDEV内核模块。在此基础上本文提出了一种基于历史开销的虚拟控制平面实例间流量隔离机制。通过在LinuxLXC虚拟机环境下部署VNETDEV内核模块，对多个的虚拟控制平面实例进行的流量测试验证能够保证各虚拟控制平面实例间的流量公平性和隔离性。
In order to ensure the fairness of the virtual router to control the bandwidth resource of the planar link and the traffic isolation, in this paper, we design and implement the middle tier of communication, VNETDEV kernel module, between the virtual control plane and the logical forwarding engine based on the Linux system. On this basis, this paper proposes a traffic isolation mechanism in virtual control plane instances based on the historical cost. Through arranging the VNETDEV kernel module under the LinuxLXC virtual machine environment, verification of flow test for multiple virtual control plane instances can ensure the fairness and isolation of traffic between each virtual control plane.
