Problems solved by technology

However, the various protocols currently in use cannot provide dual-link control by themselves, and cannot realize the protection of the master and backup of the control path of the device; or, when implementing dual-link protection, the configuration data settings between the master and slave devices are cumbersome, and must be configured on the master and slave devices at the same time. set data

Embodiment Construction

[0023] The present invention realizes the main-standby dual-link protection of two control links by setting the main link and the backup link on the control path between the master-slave equipment (including the master control equipment and the slave equipment), and the communication The master-slave device control path in the device performs master-standby protection. Whether there is a problem with the master-standby link or a problem with layer 2 (data link layer) or layer 3 (network layer), the control path can be switched from the current master link Switch to the backup link to ensure that the master-slave device control path is normal.

[0024] The following takes the access media gateway as an example to describe the dual-link active / standby protection of the control channel between the master and slave devices in detail.

[0025] First, the connection mode between the master and slave devices.

[0026] The master-slave devices can be connected in various ways, such a...

Abstract

A method for achieving double link between a master device and a slave device is disclosed in the invention, comprising the following steps of: setting configuration data for a default link on the master device and the slave device; while starting, establishing a default connecting link in a control path between the master device and the slave device based on the configuration data for the default link; after the default connecting link is established normally, assigning the connecting configuration data of a reserve link onto the slave device from the master device via the default connecting link. Therefore, while in the event of the failure of the control link, the communication path between the master device and the slave device can be effectively protected by the technical proposal of the invention, accordingly, the protection of the control link is achieved.

Description

technical field [0001] The invention relates to a protection technology for a control channel between master and slave devices, in particular, to a method for realizing dual links between master and slave devices. Background technique [0002] In the communication equipment, the links between the existing master-slave equipment, single board and main control board are mostly single-link. The control channel between the master-slave device of important communication equipment needs to have a dual-link master-standby protection mechanism, so as to ensure that in the event of a link error, the other link can take over and continue to work, and the device can continue to work. normal operation. [0003] The channel control between the master and slave devices can adopt multiple connection methods such as HDLC High-Level Data Link Control (HDLC High-Level Data Link Control), Ethernet, etc., and a mixed method can also be used if necessary. However, the various protocols current...
