Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] The embodiment of the present invention provides a protection switching method. figure 1 It is a schematic flow chart of the protection switching method according to the embodiment of the present invention Figure 1 ;Such as figure 1 As shown, the method includes:

[0057] Step 101: the first node device identifies the received message when detecting signal degradation;

[0058] Step 102: When the first node device recognizes that the message is an OAM message, fill the first identifier in the OAM message, and send the modified OAM message; wherein, the first identifier is used for Indicates signal degradation.

[0059] The protection switching method of this embodiment is applicable to a network for information forwarding based on Layer 3 Segment Routing (SR) technology. The transmission tunnel is composed of a series of ...

Abstract

The embodiment of the invention discloses a protection switching method, node equipment and a storage medium. The method comprises the following steps that: first node equipment identifies a receivedmessage under the condition that signal degradation is detected; when the first node equipment identifies that the message is an operation, maintenance and management (OAM) message, the OAM message isfilled with a first identifier, and the modified OAM message is sent; wherein the first identifier is used for representing signal degradation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a protection switching method, node equipment and storage medium. Background technique [0002] The protection switching of the transmission network is a basic function. In addition to establishing the working path, the service also establishes the protection path. When the working path fails, it will trigger the switchover to the protection path as soon as possible to ensure that the service performance is not affected as much as possible. [0003] A working path may be a link including multiple nodes. When the intermediate node fails, if the signal fails, the source and sink nodes at both ends can detect the fault and trigger switching. However, if the intermediate node suffers from performance degradation, since many performance degradation detection methods are point-to-point detection, then Only the degraded intermediate node can detect the performanc...
