Abstract: In order to adapt to the development of the demand for future network, the researchers pay urgent attention to the next generation network architecture. As the core equipment of the virtual network platform construction, which is one type of future network architectures, the design and implementation of the virtual router system is the research hot spot. This paper presents a management and control plane for virtual router. It introduces the design and implementation of virtual router control plan, analysis functional modules and key technology. The paper makes solution which combines container-based virtualization technology, C language, shell script, Netlink protocol, Quagga routing management software and other technology to realize the plane in the Linux operation environment. System test results show that the control plane can allocate physical device resources effectively, and isolate virtual router generation and management efficiently, manage network information and realize the interaction with the forwarding plane. Based on high performance, system design makes the control level of system flexibility, portability and extensibility.

Key words: router, management and control plane, container, virtualization technology, routing management software, Netlink protocol
