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 single optical fiber fault processing method and device. When a non-decision-making node in a cross-network element multiplex section protection group detects an alarm message that triggers a multiplex section protection group switchover, it judges that the cross-network element multiplex section Whether the communication link status between the decision nodes in the protection group is normal, if the communication link is abnormal, the alarm information is mapped to the sending fiber end of the protection group as the opposite end. The invention can solve the problem of traffic interruption when a single optical fiber fails when a communication link fails.

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 Telecommunications Standardization Sector) G.841, which provides protection for the multiplex section layer of SDH (Synchronous Digital Hierarchy) network , is a dedicated or shared protection mechanism, suitable for 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-node multiplex section protection group, wherein a single-node multiplex section protection group i...
