Abstract

Provided are a method and a system for establishing an end-to-end label switched path. The method comprises: a first node ascertains an end-to-end label switched path from the first node to a last node, said path comprising nodes corresponding to integrated devices and nodes having single switching capability; path request messages are sent to establish the end-to-end label-switched path hop by hop. Embodiments of the present invention can establish an end-to-end path integrated with multiple switching capabilities.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for establishing an end-to-end label switching path. Background technique [0002] With the development of communication technology, converged devices appear, which can support multiple switching capabilities, for example, Packet-Optical Transport Network (P-OTN) devices, which can support wavelength switching, time division multiplexing (Time Division Multiplexing, TDM) switching, packet switching. When such a converged device appears, the end-to-end service may pass through nodes with different switching capabilities. For example, an end-to-end service needs to pass through the packet switching domain and the TDM domain, and the packet switching domain and the TDM domain are connected by a converged device , then when establishing a path at this time, in the prior art, a Label Switch Path (Label Switch Path, LSP) will be established correspon...
