Abstract:
Devices, networks, storage media, and methods for identifying client devices across a network address translation border. The devices include devices that perform the methods. The methods include methods of generating client-specific identifiers for a protocol data unit (PDU) utilizing a network address translation (NAT) device that performs network address translation. The PDU includes a header and a payload and these methods include embedding a client-specific tag within the header of the PDU to generate a modified PDU and transmitting the modified PDU and a client table to an upstream device. The methods also include methods of interpreting client-specific identifiers within a PDU with an upstream device. These methods include receiving the client table and the modified PDU with the upstream device and determining, based upon the modified PDU and the client table, a unique client identifier of a given client device.

Claim (Index 1):
A method of generating client-specific identifiers for a protocol data unit (PDU) utilizing a network address translation (NAT) device that performs network address translation, wherein the PDU includes a header and a payload, the method comprising:\n receiving, from a given client device of a plurality of client devices serviced by the NAT device and with the NAT device, the PDU; determining, with the NAT device, a unique client identifier for the given client device; establishing, with the NAT device, a client-specific tag for the given client device; storing, on the NAT device, the unique client identifier and the client-specific tag in a client table that correlates a given unique client identifier to a corresponding client-specific tag for each active client device in the plurality of client devices; transmitting, with the NAT device and to an upstream device, the client table; embedding, with the NAT device, the client-specific tag within the header of the PDU to generate a modified PDU; and transmitting, with the NAT device and to the upstream device, the modified PDU.
