Abstract
A method is disclosed for synchronizing user protocol messages between service nodes. The method includes, when receiving a user-related protocol message, a service node judging whether a state of a backup group to which a user belongs corresponding to the protocol message is active or standby on the service node, and according to a type of the protocol message, determining whether to send the protocol message to another service node on which the state of the backup group is standby or active. The method also includes, when determining to send the protocol message, the service node encapsulating the protocol message through a service backup protocol and sending the protocol message to the other service node. A service node includes a message receiving module, a state judging module and a message sending module.
