Embodiment Construction

[0099] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0100] The existing BRAS hot backup solution adopts a 1:1 backup technology, that is, a backup device is deployed for each BRAS, which will lead to serious waste of resources. exist figure 1 In the shown scenario, BRAS-2 is used to back up BRAS-1, and BRAS-4 is used to back up BRAS-3. In this solution, BRAS-2 and BRAS-4 are completely used as backup devices, and the traffic that only needs to be processed by two devices actually uses four devices. At the same time, the ports of the core router (CR) are also doubled, resulting in a serious waste of resources. In addition to the serious waste of resources, the configuration complexity of 1:1 hot backup is high (1:1 hot backup is a manufa...

Abstract

The invention provides a method, equipment and computer-readable storage medium for realizing BRAS hot backup, relates to the technical field of communication, and is used for saving network equipment resources. The method for realizing BRAS hot backup of the present invention includes: obtaining the state information of the target master BRAS device; determining the backup device of the target master BRAS device when it is determined according to the state information that the target master BRAS device fails; The backup device is used for backing up multiple master BRAS devices; the data of the target master BRAS device is transmitted by using the backup device. The invention can save network equipment resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, equipment and computer-readable storage medium for realizing BRAS hot backup. Background technique [0002] Broadband Remote Access Server (BRAS) is a new type of access gateway for broadband network applications. [0003] The existing BRAS hot backup solution adopts 1:1 hot backup technology, that is, a backup device with exactly the same configuration as the main device is used to realize the backup. Real-time synchronization of user entry information between the active device and the backup device. Once the active device has a link failure or equipment failure, the standby device will be upgraded to the active device, and at the same time, it will directly take over the forwarding of user traffic according to the synchronized user forwarding table. [0004] The existing BRAS hot backup solution deploys a backup device for each BRAS, which will lead t...
