Re: Is the lost packet not displayed in the pcap file?

[Ricardo Moura]

Hello Allan,

The ACKs are sent at different times. Do you know why?

-> it looks like you are looking at just the pcap of the transmitting node, the message is not received instantly. Also note the receiving node.

And why isn't the packet loss displayed on the pcap?

-> i think pcap does not measure lost packets. I believe that you should reduce packets received from packets sent. Better to use the flowmonitor package.

Hi ALL

I'm beginner to NS3.

I'm simulating by creating a new files below.

src>applications>helper> new-app-helper.cc, new-app-helper.h

src>applications>model> new-app.cc, new-app.h

src>applications>internet> new-header.cc, new-header.h

scratch>seq_new_app

After that, I compared the results of the pcap file and the terminal.

The ACKs are sent at different times. Do you know why?

And why isn't the packet loss displayed on the pcap?

Attached the file and the output result.
