| Abstract: | In this paper, the principles of packet capture based on Libpcap and BPF are introduced at the beginning. Then, the design and implementation of a traffic flow measurement system without additional hardware devices are described. In this system, the international traffic flow and national traffic flow are differentiated making the traffic and fee control easier. The deployment of the system in different LAN environments is explained in the end. |
