Explain sliding windows as used by TCP. What advantage does the use of sliding windows provide
over a simple Positive Acknowledgement with Retransmission (PAR) protocol?
A lost TCP acknowledgement does not necessarily force retransmission. Explain why.
Each router in the autonomous system shown below starts with a routing table showing the networks
they are directly connected to. The routers exchange routing information using a distance vector
protocol. Show the messages that are exchanged and the state of the routing tables after each message.
Use the Routing Tables sheet PDF file or
Word file.
