Through researching and analyzing the management and maintenance problems in virtual router platform, a three-layer virtual router architecture including control plane, forwarding plane and resource management plane was put forward. Control plane and forwarding plane were two basic function planes in virtual router, correspondingly carrying logical control plane and logical forwarding plane. In order to achieve dynamic management of virtual router, resource management plane was introduced. Resource management plane was regarded as one important function plane, which was used to manage and configure virtual router. The structure and mechanism of resource management plane were mainly expressed, and a prototype system to support static installment and dynamic adjustment of router instances was carried out. The experimental results prove that the maximum processing ability of resource management plane is about 3205 strategies/second, and it can complete establishment of router instance within one second, which can meet management requirements of virtual router platforms.
