  • Label switching path establishment method, data forwarding method, and device
    Patent number: 9954773
    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.
