Abstract: The present invention provides a virtual cluster establishment method and a network device. The method includes: a first network device establishes, a network-layer-based first communication connection with a second network device; the first network device sends a first registration request message to the second network device through the first communication connection, where the first registration request message is used to establish a virtual cluster with the second network device; after the first network device receives a registration response message, selecting the second network device as an active main control device in the virtual cluster system; establishes, a network-layer-based second communication connection with a third network device; sends, a second registration request message to the third network device; and selects the third network device as a standby main control device. In this invention, a structure of a cluster is simplified, and scalability of the cluster is improved.

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.

Abstract: Embodiments of the present invention provide a method, a device, and a system for controlling a network path, where the method includes: the first control device generates path information for a first AP according to network topology information, and generates first forwarding information for the first AP according to acquired forwarding resource information of the first AP and the path information, and sends the first forwarding information to the first AP; the first control device determines that a second AP which is not managed by the first control device is included in the path information, sends the path information to a second control device for managing the second AP, so that the second control device generates second forwarding information for the second AP according to the path information and the acquired forwarding resource information of the second AP, and sends the second forwarding information to the second AP.
