So i have 5 nodes A,B,C,D,E. A client, E server, rest are routers, and i would like to measure end to end delay between A and E. The only solution i can come up with is taking a time stamp in A, putting it in header, taking another time stamp at E when it recieves the packet and substract the client time stamp from server's.
Is there any more scientific way that i am not aware of?
I can sum processing delay+4*tranmission delay but i need to compute it, can't use theoretical work.
Thanks in advance. I also see there is no delay related tag, interesting.
