A method resolves connectivity of services inside a network virtualization system when a virtual cluster system supports unicast IP, L2VPN, and L3VPN services, so that the software network virtualization system can support various types of services efficiently and with high quality. The method includes: creating, on a control device, a virtualized remote logical interface for an external interface of a remote access node; identifying, by the control device according to a service configured on the virtualized remote logical interface, a service type of the service, and generating virtual link forwarding entries of the remote access node and a core aggregation node; and sending, by the control device, the virtual link forwarding entry to the remote access node and the core aggregation node, so as to set up a virtual link between the core aggregation node and the remote access node.

Method, device, and routing system for data transmission of network virtualization

A method and a system for implementing virtual circuit status consistency. A transmitting provider edge router (PE) send an extended network layer reachability information (NLRI) message to a remote PE; the remote PE updates the status of the virtual circuit from the remote PE to the transmitting PE, according to the received extended NLRI message, so as to make the status of the virtual circuits between the transmitting PE and the remote PE consistent. A system for implementing virtual circuit status consistency, the first provider edge router (PE) in the system sending an extended network layer reachability information (NLRI) message to a second provider edge router (PE); the PEupdates the status of the virtual circuit from the PEto the PEaccording to the received extended NLRI message, so as to make the status of the bidirectional virtual circuits between the PEand the PEconsistent.
