1. A method, comprising:
receiving, by a gateway of a communications network, from a device configured to communicate with the gateway, one or more packets of a packet flow initiated by the device;
determining at least one of the one or more packets comprise a Transmission Control Protocol synchronization (TCP/SYN) packet;
appending, based on the determining and to the one or more of the packets of the packet flow, at least a portion of information associated with the device, wherein the information associated with the device is maintained by the gateway and comprises at least an identifier associated with the device; and
sending, by the gateway, to a network device of the communications network, the one or more packets of the packet flow with the appended information, wherein the appended information facilitates enforcement of a per-device policy.
