Precise network monitoring for high quality live streaming

Live streaming of high quality media requires high quality network in terms of packet loss rate and jitter. However, the current IP or Ethernet network does not assure the bandwidth or jitter for streaming in general. In addition, the existing network monitoring system does not have the functionality to measure these network quality. My precise network monitoring is a packet-by-packet network monitoring to observe switching or routing latency inside of a switch, router, or network, and provide the statistics of a flow that is specified by user on-demand. We implemented this system, installed it in the existing network, and evaluated its functionality. It shows the impact of cross-traffic on a measured flow.
