Abstract :
We developed EIPMon (Enhanced Internet Protocol Monitor) in order to estimate delay variation and packet loss quality of service (QoS) measures in GTE´s IP Telephony Network and to characterize the traffic between its points of presence (POP) sites. The tool is passive in that it does nor generate any of its own network traffic in order to make its measurements. While the tool´s algorithms for estimating the QoS measures are generally applicable to network monitoring problems, the mel´s particular implementation specifically takes advantage of GTE´s network architecture and are based on information carried in RTP (Real-Time Protocol) headers which are present in the real-time traffic carried in the network
