Abstract: A method for use in a system with multiple processor-based devices, the method including: running a first application on a first processor-based device; maintaining a second application in a standby mode on the first processor-based device; and providing a service to each of the first and second applications on the first processor-based device by a service-providing application on the first processor-based device, wherein providing the service includes maintaining a record regarding service statuses of the first application and the second application in which the record stores a respective entry for each of the first and second applications to reflect an active service status for the first application and a standby service status of the second application.

Abstract: According to one aspect, the subject matter described herein includes a method for communicating an encrypted data packet. The method includes steps occurring at a first gateway node. The method also includes receiving a data packet from a first host. The method further includes determining that a first security association (SA) instance associated with the data packet is in an inactive state. The method further includes identifying a second SA instance that is both associated with the data packet and in an active state. The method further includes forwarding the data packet to the second SA instance.

Abstract: Methods, systems, and computer readable media for offloading IPsec processing from application hosts using an IPsec proxy mechanism are disclosed. According to one method, at least one of unencrypted, IPsec, and Internet key exchange (IKE) packets transmitted between a first application host and a second application host are intercepted by a network gateway. The network gateway performs all IKE and IPsec-related processing for the at least one unencrypted, IPsec, and IKE packets on behalf of the first application host such that the second application host is unaware that IPsec processing is being performed by the network gateway.
