Abstract: 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.

摘要： 通过研究与分析虚拟路由器平台在管理与维护等方面存在的问题，提出了三层的虚拟路由器体系框架：控制平面、转发平面和资源管理平面。控制平面和转发平面是虚拟路由器的两个基本功能平面，分别承载逻辑控制平面和逻辑转发平面。为了动态地管理虚拟路由器平台，引入了资源管理平面。它是管理物理资源和维护路由器实例的重要功能平面。通过阐述资源管理平面的框架以及实现机制，实现了支持路由器实例的静态创建和动态调整的原型系统。实验结果表明：资源管理平面的最大处理能力为3205条命令/秒，在1 min内完成路由器实例的创建任务，能够满足虚拟路由器平台的管理需求。
