Patent ID: 8756412

Claim:
A method comprising: determining whether a first gateway is capable of operating as a redundancy for a second gateway based on whether the first gateway includes configuration information in a system status pages (SSP) file, whether the first gateway is able to initialize the SSP file from non-volatile memory, and whether at least one network address for the first gateway has been changed; in response to determining that the first gateway is capable of operating as the redundancy for the second gateway, synchronizing the first gateway with information from the second gateway, the second gateway operating in a primary role with at least one primary network address, the second gateway communicating with at least one wireless device that uses at least one encryption key during at least one secure communication session, the information including the at least one encryption key; detecting a switchover event at the first gateway; and in response to detecting the switchover event: switching the first gateway to the primary role and communicating using the at least one primary network address; and maintaining the at least one secure communication session at the first gateway after the first gateway switches to the primary role.
