This graph shows you the delay of the tcp stack to confirm the reception for data. Please note that many tcp stacks wait a few milliseconds if there is no data to respond ( see [[https://en.wikipedia.org/wiki/TCP_delayed_acknowledgment Wikipedia TCP delayed acknowledgment]]. So any delay below above this value ( usually 40 ms ) shows a significant delay in the roundtrip time. If you have installed the Allegro close to the Skype client, it will be the roundtip time of the tcp packets from your network to the Skype could. | This graph shows you the delay of the tcp stack to confirm the reception for data.

This can be done also for tcp retransmissions and zero window. If you have installed the Allegro close to the Skype client, this will indicate if the data sent to the Skype server required a retransmission on the WAN link. | This can be done also for tcp retransmissions and zero window.
