Does anyone know how the simulator determines when to drop packets? We are losing a lot of packets in my class. So many were dropped that I think it caused issues with the students establishing and testing protocols.
Instead of thinking about how to replace an occasional missing packet, they were concentrating on how to circumventing the whole thing. Strategies included: always sending messages multiple times, send messages to multiple people to forward to the intended recipient, flooding the network with a bunch “empty” packets between message packets… basically variations of sending enough packets or copies of packets in the hopes of maybe getting at least a one copy of each packet to get through.
I was wondering if the dropping rate was based on a percent of total traffic and my kids were seeing more because each is responsible for a greater percent of traffic than they would in a larger class?
Setup was 6 students working consistently, plus me occasionally trying out a pair’s protocol, spread out over 6 routers (I think 4 had students, 2 empty).
Thanks for any illumination.
