Abstract: The method of establishing a multicast data channel in a network virtualization system includes: creating, on a controller, a virtual remote logical interface for an external interface of a remote node; generating, a multicast tree tunnel that uses a core node as a root, and obtaining a multicast protocol packet sent by a device outside the network virtualization system; acquiring, a multicast source address and a multicast group address from the multicast protocol packet, and generating a multicast forwarding table; searching, the multicast forwarding table for an external interface of the core node, searching for an outbound interface of the multicast tree tunnel on the core node according to the multicast tree tunnel, and generating a P2MP PW forwarding table of the core node, and sending the P2MP PW forwarding table of the core node to the core node. The method implements a multicast service in a virtual cluster router.

Abstract: 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.

Abstract: Embodiments of the present invention provide a label switching path establishment method, a data forwarding method, and a device. The establishment method includes: determining, by a first service controller, each hop on an LSP from a preset ingress to a preset egress, allocating, from first label space information of each hop, a label to each hop, determining incoming and outgoing information of each hop according to topology information of each hop, generating forwarding data of each hop, and sending the forwarding data of each hop to a node device corresponding to each hop to complete establishment of the LSP. A technical solution of the present invention can alleviate burden of a node device in an MPLS network and increase the number of LSPs that the node device is capable of supporting.
