Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for end-to-end scheduling of optical layer wavelengths. Background technique [0002] In a transmission network management system, an end-to-end optical layer wavelength is generally represented as an OCh (Optical Channel, optical channel) path. Optical layer wavelength end-to-end scheduling is mainly reflected in: optical layer wavelength service configuration. [0003] At present, the optical layer wavelength service configuration method is: when implementing the optical layer wavelength end-to-end service, manually configure the optical layer wavelength service one by one network element (ie site), one by one board, and one by one optical layer wavelength. For example, for a certain optical-layer wavelength selected by the user, the source and sink ports of the optical-layer wavelength service are configured on a board-by-board basis in units...

AI Technical Summary

Problems solved by technology

[0006] The manual configuration of each board leads to complex configuration of optical layer wavelength services and low end-to-end scheduling efficiency of optical layer wavelengths

Especially when the optical layer wavelength needs to pass through multiple network elements, multiple boards, or in multi-dimensional scheduling application scenarios, the complexity of the above manual configuration is very high, and the end-to-end scheduling efficiency of the optical layer wavelength is particularly low

During the manual configuration process, if the wavelength, port and other information of any one of the boards are manually configured incorrectly due to human error, the optical layer wavelength service cannot be opened normally. Therefore, the correct rate of optical layer wavelength service configuration is low.

[0007] When querying the route of the optical layer wavelength service, for a site in the route of the optical layer wavelength service, the route of the optical layer wavelength service can only be viewed segmentally by board. It is difficult to clearly reflect the route of the optical layer wavelength service, especially For network elements with concentrated optical layer wavelength scheduling, it is more difficult to clearly reflect the routing of optical layer wavelength services

In addition, when there is a problem with the optical layer wavelength service, it is impossible to quickly find the route of the problematic optical layer wavelength service, which leads to problems such as untimely fault location, inability to quickly troubleshoot faults, and heavy maintenance workload.

[0008] In summary, the current wavelength end-to-end wavelength service scheduling method cannot meet the needs of the transmission network management system
