Abstract

An embodiment of the invention provides a hot-standby method, a hot-standby device and a hot-standby system. The hot-standby method comprises the steps of storing first user information in main equipment into a local buffer memory module of the main equipment by the main equipment; and furthermore, transmitting the first user information to a remote buffer memory module of first backup equipment according to preset association information so that the first backup equipment acquires the first user information from the remote buffer memory module of the first backup equipment and restoring the first user information when a failure of the first equipment is detected. Obviously, the hot-standby method, the hot-standby device and the hot-standby system provided by an embodiment of the invention have functions of realizing the hot-standby function of multiple sets of equipment, quickly restoring the user information of the failed equipment, and improving restoring efficiency.

Description

technical field [0001] Embodiments of the present invention relate to Internet technologies, and in particular to a hot backup method, device and system. Background technique [0002] In current network applications, in order to avoid the risk of network interruption due to single point of failure, for service nodes at the aggregation layer or edge layer, it is necessary to support dual-system hot backup between devices. [0003] In the existing dual-machine hot backup method, one active device and one backup device form a hot standby group; when a user in the active device goes online, the active device sends the corresponding user The information is saved in an external database shared with the backup device, so that when the main device fails, the backup device reads the user information from the external database and restores the user information of the user . [0004] However, in the dual-system hot backup method in the prior art, the time delay for restoring the user...
