Disclosed are a virtual routing system and method, the system comprises: level-1 routes configured to provide a layer-3 routing function for communication between virtual machines of different virtual networks within the calculation nodes of a data center virtual platform, and providing source address translation/destination address translation to the data center network external to the calculation nodes; level-2 routes configured to provide a layer-3 routing function for communication between virtual machines of different virtual networks between the calculation nodes; border gateway routes configured to provide source address translation/destination address translation to an external network for a data center virtual platform. The present invention solves the problem in the relevant art of a single carrier node for virtual routes, improving network performance and availability of the data center, and reducing the physical network bandwidth consumption by the communication between virtual networks. |
