A technique for maintaining secure network connections is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for maintaining secure network connections. The method may comprise detecting a change of address associated with a first network element. The method may also comprise updating at least one first security configuration at the first network element. The method may further comprise transmitting at least one secure message from the first network element to a second network element, wherein the at least one secure message comprises information associated with the change of address. And the method may comprise updating at least one second security configuration at the second network element based at least in part on the at least one secure message.

Technique for maintaining secure network connections

To prevent loss of packets due to failover between server systems in which a failover mechanism is provided in a first server system to enable a second server system to failover to the first server system, the first server system includes a first sequence number space that is different from a second sequence number space in the second server system. The first and second sequence number spaces are part of a total sequence number space. After failover from the second server system to the first server system, the first server system sends packets containing sequence numbers in the first sequence number space which are defined by a security protocol.
