Abstract: A network flow monitoring and analysis system comprises flow labeling agent(s), sensor(s), controller(s), and correlation engines(s). The flow labeling agent(s) label at data packet flow unique and covert label(s). The sensor(s) observe data packet flow for the unique and covert label(s) and generate examination report(s) from the observations. The examination report(s) comprise information such as: location information; time information; target information; path information; and flow information. The controller(s) communicate instructions to the labeling agent(s) and sensor(s), receive event information and manage the correlation engine(s). The correlation engine(s) correlate information from information such as the target information; event information; path information; and flow information.
