Web2.1 Overview of Measuring TCP RTT A TCP connection carries bi-directional data streams between two end hosts. In our application scenario, one end host resides in our local network and the other is a remote host, similar to [1].At the vantage point, we can see both incoming and outgoing TCP packets, and observe TCP sequence (SEQ) and … WebA. Packet Level Analysis The RTTs of packets in the August 31, 2004 trace are plotted in Figure 1. The average RTT observed in this trace was 168.9msecwith 50% of the RTTs falling below 76.1msecand 75% of the values falling below 151.4msec. The maximum RTT observed is 19.6sec.
