Embodiment Construction

[0037] In order to facilitate the description of the present invention, the implementation of the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0038] This implementation mode provides a single fiber fault handling method, which mainly adopts the following scheme:

[0039] Checking the non-decision-making node corresponding to the link failure of the protection port, judging the state of the communication link with the decision-making node, and mapping the corresponding alarm information to the sending end of the single-fiber fiber in the case of the failure of the communication link, Force the peer to detect a failure.

[0040] refer to image 3 , the single fiber fault processing method...

Abstract

The invention discloses a method and a device for handling a single optical fiber fault. The method comprises the following steps: when a non-decision node in a cross network element multiplex section protection group detects the warning information of triggering the switching of the multiplex section protection group, judging whether the communication link between the node and a decision node in the cross network element multiplex section protection group is in a normal state or not, and if not, mapping the warning information to a sending optical fiber end which serves as a protection group at an opposite end. Due to the adoption of the method and device, the problem of flow interruption caused by the fault of a single optical fiber in case of fault of the communication link can be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a single optical fiber fault processing method and device. Background technique [0002] Linear multiplex section protection is defined in ITU-T (International Telecommunication Union Telecommunication Standardization Sector, International Telecommunication Union Telecommunication Standardization Sector) G.841, which provides multiplex section layer for SDH (Synchronous Digital Hierarchy, synchronous digital system) network Protection is a dedicated or shared protection mechanism applicable to point-to-point physical networks. A multiplex section can be used to protect a certain number of working multiplex sections, but it cannot provide protection against node failures. The multiplex section can work on single-ended or double-ended. In addition, the protection can also be used to open additional business. [0003] Such as figure 1 Shown is a traditional single-n...
