Method and system for recovering access user information in IPOE (Internet Protocol over Ethernet) scene

The invention relates to the technical field of computer communication, and provides an IPOE scene access user information recovery method and system. The IPOE user management module receives the interface online state notified by the interface management, and the IPOE user management module uses the interface name to search the restarted interface index; the database server matches an interface corresponding to the user table and returns related IPOE user table items to the IPOE user management module; and the IPOE user management module recovers the IPOE user table item, and issues and forwards an ACL flow filtering rule to release the user flow at the same time. According to the invention, the influence of extra flow triggering or message interaction flow on the network performance is avoided, the requirements of other devices in the network on the network performance are ensured, the user information is directly recovered through the database, the user cutoff time is effectively reduced, and the user expe
