1. A method for maintaining secure network connections, the method comprising:

  • duplicating, at a third network element, a security association associated with a secure network connection between a first network element and a second network element, wherein a lookup of the security association associated with the secure network connection is not dependent on any destination address; and

    in response to detecting failure of the second network element, replacing the second network element with the third network element in the secure network connection with the first network element, wherein the secure network connection between the first network element and the third network element is based on the duplicated security association; and

    sending at least one secure message from the third network element to the first network element to notify the first network element that the secure network connection will be taken over by the third network element, the third network element communicating with the first network element without the third network element reestablishing another secure network connection with the first network element.
