Patent ID: 7639648

Claim:
A network of wireless switches, comprising: an initial home wireless switch of at least one wireless client device in a first mobility domain, wherein wireless client device is initially homed with the home wireless switch and the initial home wireless switch is not also the current wireless switch of the wireless client device, wherein the initial home wireless switch has a first IP address; other peer wireless switches in the first mobility domain; and a backup home wireless switch in the first mobility domain and having a second IP address, the backup home wireless switch comprising a processor, a first wireless client database (WCDb), a failure detection module configured to detect failure of the initial home wireless switch, and a transmitter; and wherein the processor updates the first IP address in the first wireless client database (WCDb) with the second IP address for each of the wireless client devices of the initial home wireless switch to reflect that the backup home wireless switch has assumed responsibility for the wireless client devices previously homed to the initial home wireless switch, when the failure detection module detects failure of the initial home wireless switch, wherein the processor synchronizes the first WCDb to wireless client databases (WCDbs) of the other peer wireless switches, and wherein the other peer wireless switches synchronize their respective wireless client databases (WCDbs) to the first WCDb so that the WCDb of each wireless switch in the first mobility domain has the IP address of the backup home wireless switch associated with the wireless client devices.
