All of the connections detected are listed in the upper left corner of the MultiHop Analysis display. Choose each connection you want to analyze by clicking on its corresponding check box. For the MultiHop Analysis display, it is usually more useful to look at one connection at a time.
The Hop Summary view shows delay data from the selected connections in aggregate, giving you the average delay time from multiple conversations over time. Knowing what is “normal” can help you determine when applications or third party service providers are performing adequately.
Most of the metrics (minimum and maximum delay times in total and by segment, for example) should be self-explanatory. Lost Packet Delay Time measures how much delay was introduced by dropped packets having to be re-sent.
 
 
The Summary Statistics view of MultiHop Analysis gives you a textual display of the selected connections (computed in the MultiHop Delay Analysis – Connection Dynamics view). You may select one or many connections. The statistics summary gives you details on the analyzed packets, such as: number of packets analyzed, delay time, matched packets, direction of packets, dropped packets (will be displayed in red type), time of first packet, and time of last packet.
The first part of the summary shows paths to all of the buffer files currently being analyzed and summarizes settings in effect. The second part of the summary shows essentially the same measurements as the MultiHop connection dynamics and MultiHop Analysis displays, summarized in a list format. As in the MultiHop Analysis display, Lost Packet Delay Time measures how much delay was introduced by dropped packets having to be re-sent.
