Title: SERVICE PATH ESTABLISHMENT METHOD, NODE DEVICE, AND SYSTEM
Abstract:
Disclosed in an embodiment of the invention are a service path establishment method, a node device, and a system. The service path establishment method comprises: a network controller receives a first label-switched path (LSP) service path request message, wherein the first LSP has a service relevance attribute, the service relevance attribute of the first LSP indicates inclusion of at least two second LSPs in the first LSP, and the first LSP and the at least two second LSPs have the same start node and end node; the network controller calculates routing information of the second LSPs; and the network controller transmits the routing information of the second LSPs to a transport plane, so that the transport plane establishes the first LSP according to the routing information of the second LSPs. The above technical solution enhances service performance of a first LSP, and simplifies maintenance and management of a service path.
