Hi all, I have to write a protocol that simulate this behaviours :
The sender wait one ack for each 2 packet that was sent The receiver send only one ack for each packet that was received the window and the buffer sizes are different. The nodes of this network will be like this : A ---------------- B ------------------- C A-B : bw 1Mb delay 50ms B-C : bw 0.5mb delay 50ms There will be needed 3 parameter form the user : The buffer size at B , ack interval from C to A and simulation time. In this project how can i make possible to send one ack for each 2 packet from receiver and slide the window when ack comes for the 2 packets at the sender. Can it be possible via implementing my own tcp agent? If it is how can it be. I'm new to ns2 and i don't know very much about it? Is searched the isi manual and i could not find any topic can help me. Do you know any source or have any sample code that i can use? Thanks,
