TCP end to end delay

[Abdullah Orman]

Hi everyone

 I want to display, but with the ever-value "0" I'm getting. UDP applications do not have such a problem.

 Although I made the following change:

1- omnet.ini :

**.scalar-recording = true
**.vector-recording = true
**.endToEndDelay.scalar-recording = true

**.srv[1].tcpApp[*].typename = "TCPSessionApp"  # ftp
**.cli[1].tcpApp[*].typename = "TCPSinkApp"

2-TCPSessionApp.cc :

 msg->setTimestamp();

 

3-TCPSinkApp.ned

@ statistic [endToEndDelay] (title = "end-to-end delay"; source = "messageAge (rcvdPk)"; unit = s; record = histogram, vector; interpolationmode = none);
 

 End-to end TCP packet delay and jitter How do I get graphics. Can you help me?

 

Best regards.

since TCP depends on the acknowledgement of the both parties communicating so the end to end delay is not that significant as compared to RTT you can just calculate average e2e delay using RTT/2 .

try this **.endToEndDelay.result-recording-modes=mean

it worked for me
