Abstract

The embodiment of the invention provides a method and a device for triggering the switching of bypass equipment, and a method and a device for switching the bypass equipment. The method for triggering the switching of the bypass equipment comprises the steps that the real-time flow rate of straightway equipment is detected; whether the flow rate of the straightway equipment is normal or not is judged; and if the flow rate of the straightway equipment is abnormal, switching indication information used for triggering the bypass equipment to switch a communication link to a protection pathway is sent. The method for triggering the switching of the bypass equipment, which is provided by the embodiment of the invention, has the advantages that the bypass equipment is triggered to switch the communication link to the protection pathway through detecting the abnormal conditions of the flow rate at the inner part of the straightway equipment, so that the switching reliability of the bypass equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method for triggering bypass device switching, a bypass device switching method and a device. Background technique [0002] In the process of network communication, more and more networks adopt the in-line deployment method, that is, in-line devices are connected in series between network devices or in the links between networks. Once the in-line devices fail, the entire link communication will be caused. Therefore, it is necessary to protect the link where the in-line device resides, so as to improve the reliability of the network. [0003] At present, the bypass technology is generally used to protect the link where the direct device is located. The principle is: the bypass device detects the optical signal of the outgoing interface of the direct device in real time. When no optical signal is detected at the outgoing interface of the direct device, it is...
