Abstract

The invention discloses a channel detection method and access equipment. Through setting the channel detection method, channel detection can be achieved between the two pieces of access equipment supporting different protocol standards without changing a hardware structure of the original access equipment, so that the channel detection method becomes simple and efficient, and the channel detectionbetween the different access equipment under a new network environment is effectively solved; in addition, according to the method provided by the embodiment of the invention, the content of a firstprotocol standard channel detection message does not need to be understood, only a corresponding second protocol standard protocol conversion message needs to be found in a mapping table according toa first identifier of the first protocol standard channel detection message, so that the conversion efficiency of the first protocol standard channel detection message can be greatly improved, and thus improvement on the channel detection capacity is facilitated.

Description

technical field [0001] The invention relates to the technical field of channel detection, in particular to a channel detection method and access equipment. Background technique [0002] In order to ensure the reliability of business between customers, redundant backup channels are generally provided, that is, standby channels, to avoid problems such as packet loss or service interruption when the main channel fails, and improve service reliability. Such as figure 1 The schematic diagram of the network structure of the private line service is shown. The end-to-end private line service needs to pass through the access layer device 1, the convergence layer device 2 and the core layer device (not shown). Since there will be multiple devices in the middle, the fault point of the network For high-level services, a backup channel must be provided to ensure normal communication between devices; among them, a1 indicates the main channel, and a2 indicates the backup channel. When the...
