Question

The network referenced is shown in the picture below:

Assume the network uses packet switching and 2 Kilobyte packets. Assume both L1 and L2 each have a propagation delay of 0.1 seconds. We are sending a 100 Kilobyte file.

If L1 has infinite bandwidth, and L2 has a bandwidth of 1 Megabit (125 Kilobytes) per second, how long does it take to send the entire file?
After the entire file is sent, a single acknowledgment is needed to say the file arrived, how long does the entire process take now (you can assume the ack has negligible size)?
If a maximum of 10 packets can be sent per an RTT (this is the equivalent of a fixed window size of 10 packets), how long does it take to send the entire file?
What if we start with a congestion window of 1 packet in slow start phase and no slow start threshold, How long to send the entire file now (Hint: This is similar to the previous question but with a variable window rather than fixed)?
What if we start in congestion avoidance (linear growth)?
