摘要： A method for profiling network traffic. The method includes capturing, from the network traffic using a packet capturing device, a plurality of packets, identifying a first portion of the plurality of packets as a first flow based at least on a common Internet Protocol (IP) address assigned to each packet of the first flow by a network address translation (NAT) device, extracting, by a hardware processor separate from the NAT device and based on an NAT profile of the NAT device, a first data item from the first flow, wherein the first data item is inserted into the first flow by the NAT device for identifying a first host device coupled to the NAT device, and determining, by the hardware processor based on the first data item, that the first flow is generated by the first host device.
