Service recovery method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention relates to the field of communication, and discloses a service recovery method and device, electronic equipment and a storage medium. In the invention, the service recovery method comprises the following steps: acquiring a rerouting calculation result corresponding to each potential fault of an optical layer network; when detecting that the optical layer network has a fault, querying a rerouting calculation result corresponding to the fault in rerouting calculation results corresponding to each potential fault; sending a service recovery instruction to the related site according to the queried rerouting calculation result, so that the related site carries out service recovery; wherein the related site is a site through which a recovery path corresponding to the rerouting calculation result passes, the rerouting calculation result corresponding to each potential fault of the network is obtained in advance, the pre-stored rerouting calculation result is directly inquired when the fault occurs, the rerouting calculation result corresponding to the fault is determined, and the recovery path corresponding to the rerouting calculation result is recovered. And according to the determined calculation result, a service recovery instruction is sent to a related station to carry out service recovery, so that the service recovery efficiency is greatly improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a service recovery method, device, electronic equipment, and storage medium. Background technique [0002] Optical Transport Network (OTN) technology is a new type of optical transmission technology system, which inherits the advantages of Synchronous Digital Hierarchy (SDH: Synchronous Digital Hierarchy) network and Wavelength Division Multiplexing (WDM: Wavelength Division Multiplexing) network , which has the advantages of large capacity and good control mechanism. OTN can realize functions such as transmission, switching, and multiplexing of signals of various granularities. At the same time, OTN can support a variety of upper-layer services and protocols, and is an important networking technology for bearer optical networks. [0003] Automatically Switched Optical Network ASON (Automatically Switched Optical Network) technology realizes functions su...

Problems solved by technology

[0005] The inventors of the present invention found that the current service recovery technology has the following problems: the end-to-end recovery time is too long. At present, the batch service recovery technology is limited by the time limit of optical layer service path calculation, and the end-to-end recovery time usually reaches minutes level, which seriously affects the service quality of the network business. When the network fails, the existing technology cannot provide a service recovery solution that meets the demand.
