Abstract

The embodiment of the invention discloses a path selection method and a path selection device, which are used for selecting a target path for transmitting service data based on attribute information of an SRLG bearing an OMS. Specifically, the path selection device determines an optical multiplexing segment (OMS) topology between a source node and a destination node, and obtains attribute information of a shared risk link group (SRLG) corresponding to each OMS. Then, a target path is selected according to the attribute information of the SRLG, the target path being used for transmitting traffic data from the source node to the destination node through at least one OMS of the plurality of OMSs. As the attribute information of the SRLG can reflect the actual attribute of the physical optical fiber section / optical cable section, the target path with lower fault risk is selected according to the attribute of the SRLG, which is beneficial to improving the reliability of service transmission.

Description

technical field [0001] The embodiments of the present application relate to the technical field of optical networks, and in particular, to a path selection method and a path selection device. Background technique [0002] Automatically switched optical network (ASON) technology refers to the optical transmission network that can complete the automatic switching function of optical network connection under the signaling control of the management and control system or ASON controller, and has the ability to dynamically configure network resources on demand . The core of the ASON technology is to introduce a control plane into the optical transport network, realize real-time and dynamic on-demand configuration of network resources, optimize the use of wavelength resources in wavelength division multiplexing (WDM) networks, and realize the intelligence of optical networks. change. [0003] In the traditional technology, the management and control system or the ASON controller ...
