Unexplained packet losses in NS-3: Where is my packet?

The NS-3 simulator tries to mimic as close as possible the journey of a packet through the IP-stack’s layers. Passing the packet from one layer to the next one is done through Callbacks or functions which access the packet. In this way, NS-3’s callbacks are taking successively control over the packet, which remains static.

Network Simulator 3 (NS3) is a simulation tool for researchers investigating MAC and Network layer performance; it’s being used more and more within the networking research community.
