Problems solved by technology

[0003] However, in some tunnel links, such as SR-TP (Segment Routing-Transport Profile, transmission-oriented segment routing) tunnels and SR-BE (Segment Routing-Best Effort, best-effort segment routing) tunnels, in When an intermediate cross-segment occurs, because the intermediate node only has the label information of its own node and does not know the labels of other cross-segments, if signal degradation occurs, the signal degradation warning information cannot be transmitted, which will lead to service interruption and cannot guarantee the robustness of the business

Abstract

The invention provides a signal degradation alarm method and device, terminal equipment and a storage medium, and the method comprises the steps: writing signal degradation alarm information into a preset field of a message; and sending the message of which the preset field carries the signal degradation alarm information to a corresponding receiving end on a link, so that the receiving end starts protection switching or route reselection of the link when detecting that the preset field of the message carries the signal degradation alarm information. According to the invention, the signal degradation alarm information is written into the preset field of the message, so that the end-to-end message carries the intermediate cross-segment SD state, a related link is timely notified to carry out protection switching or route reselection, at least the problem that the link is timely notified to carry out rapid protection switching when the intermediate cross-segment link has signal degradation in an SR-TP tunnel can be solved, and when signal degradation exists in a middle cross-segment link of the SR-BE tunnel, an SD alarm link is avoided, and a new link is selected again, so the robustness of the service is ensured.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a signal degradation warning method, a signal degradation warning system, a terminal device, and a computer-readable storage medium. Background technique [0002] In the packet transport network (Packet Transport Network, referred to as PTN) link signal degradation alarm scheme, the current bit error scheme of MPLS-TP (Multi-Protocol Label Switching Transport Profile, multi-protocol label switching based on transmission profile) tunnel, adopts The bit error rate of the FCS (Frame Check Sequence, Frame Check Sequence) of the port where the tunnel is located is propagated to the segment layer, tunnel and pseudo-wire. If a bit error occurs on a port in a certain span in the middle, after calculating the bit error rate and SD (Signal Degraded, signal degradation) status of the port, send FEI (Forward Error Information, forward error notification) message to the...
