Abstract
Techniques are described for load-balancing deterministic NAT functions in a mobile gateway or other device in which subscriber sessions are distributed across a plurality of session management cards. Each of the session management cards may host a non-contiguous set of public addresses and a non-contiguous set of private network addresses associated with the subscriber sessions. To facilitate deterministic NAT under such conditions, each of the session management cards locally maps the non-contiguous set of public network addresses to an internal contiguous sequence of identifiers for the public addresses and maps the non-contiguous set of private network addresses to an internal contiguous sequence of identifiers for the private addresses. Each of the session management cards may then perform deterministic NAT on packets based on the contiguous sequence of identifiers for the public addresses and the contiguous sequence of identifiers for the private addresses internal to the session management card.
