Hi,

I am working on detecting the traffic flow by using FlowMonitor.

A simple test model is developed by creating a two-node system, sending and receiving node.

Four packets are designed to be sent at the same time over UDP-IPv4.

According to Flowmon, only the first 3 packets reached the destination and 1 lost.

But, the *.pcap files indicate that both sending and receiving node has captured 4 packets.

There are two different results in the same simulation.

I have attached the NS-3 code and the two Pcap files from sending and receiving nodes.

Does anyone have a similar problem like this?

Please share the reason to cause this problem and/or a solution if it is possible.

Thanks,

Ryan

I am also facing similar issue, have you figured out why it is happening?
