For future me: introduction of how the network layer works. The local idea and the global idea of how the packets are transmitted from each end of the network to the other end of the network and how the router knows where it is going to receive the packet and where it was going to send that packet. That was one of the most interesting pieces of softwares that the mankind ever built.

"It might appear that *best-effort service* is a euphemism for *no service at all*" -- that was great!
