"address the unreliability" seems a little vague, it might imply that if a packet is not delivered properly then we just report that and return no value (which addresses it) or it could mean we do something about the packet not being delivered and re...

The project description says that we need to handle any issues which occur with the unreliable UDP. Does this mean that we need to implement some sort of stop and wait protocol to ensure the datagrams are delivered properly?

On the Getting Started page it says that something like this might be a typical invocation for a station server (for python files) . station-server.py Greenwood-Stn 2402 2560 host4 2567 host1 2408 .... To get a python script to run like this w...

Yeah, I realised that just sys was enough after I sent out the post, thanks for the reply

Is there a quick(er) way to close the instances of py processes which have opened up all the servers. At the moment I've been finding the processes and killing them manually using pgrep -af python3 then finding the right ones then killing But is the...

In python, to start a station server we need the ability to get the arguments from the commands which invoke the stations. Are we allowed to import sys or the getopt module from python to achieve this?

not sure if your answer already covers this but, like you said the network layer deals with routing of packets. Since packets may take different routes to reach a destination (through different routers) the packets need to be numbered so that at the ...

I'm unsure how to answer this question Given that Data Link Layer protocols already employ sequence numbers, provide 2 distinct motivations for Network Layer protocols also employing sequence numbers.

For this question, I understand the difference between the NZR and Manchester but am unsure at 2 distinct reasons as I have just one primary reason. Local area networks (LANs) employ sophisticated signal encoding techniques, in preference to the naive...
