Method for backing up user information and apparatus in standby service node for backing up user information

摘要

A method and apparatus for backing up user information are disclosed. The method includes: establishing a plurality of selection switch protocol groups between a same port of a standby service node and ports of a plurality of main service nodes respectively; the standby service node regularly receiving user information of access users from the ports of the plurality of main service nodes, and storing the user information to a main control unit of the standby service node; keeping a detection relation between the same port of the standby service node and the ports of the plurality of main service nodes; the standby service node sending to an interface unit of the standby service node the user information of the access user of that port stored in the main control unit, and according to the selection switch protocol, switching the same port of the standby service node to be main.

1. A method for backing up user information, comprising:
establishing a plurality of selection switch protocol groups between a same port of a standby service node and ports of a plurality of main service nodes respectively; the standby service node regularly receiving user information of access users from the ports of the plurality of main service nodes, and storing the user information to a main control unit of the standby service node; the port of the standby service node and the ports of the main service nodes detecting operational states in each other; and when detecting that the operation of any one of the main service nodes fails or detecting that any of the ports of the main service nodes is unreachable, the standby service node sending to an interface unit of the standby service node user information of the access users of the failed main service node or the unreachable port of the main service node from the main control unit of the standby service node, and the standby service node, according to the selection switch protocol, switching the port of the standby service node to be main.
