Abstract
A technique is disclosed for synchronizing NAT information stored on different network devices that have been configured to implement a network address translation protocol. Each of the network devices includes a respective NAT data structure configured to store NAT information. The NAT information includes at least one NAT entry relating to a network node engaged in a communication session with at least one other network node. At least one NAT entry in a first NAT data structure is modified. The first NAT data structure is associated with a first NAT network device. A first NAT transaction message is generated which includes information relating to the modifications performed on the first NAT data structure. The first NAT transaction message is transmitted to at least one other NAT network device to thereby cause that device to modify its respective NAT data structure using information from the first NAT transaction message. In this way, synchronization of NAT information stored on each of the network devices may be achieved.
