Abstract
A method and system for mapping security parameters to a plurality of network sessions is provided. A responding computer maps the security parameters to the combination of packet parameters and a mapped port value used in each of the plurality of sessions. The packet parameters includes IP source and destination addresses, application source and destination ports and protocol type. The mapped port value is assigned by the responding computer to maintain a unique mapping between each security association and each network session.
