Suppose frames are limited to 1,500 bytes (excluding the 18 bytes of the header and the trailer) between source Host A and destination Host B. What would be the number of frames required to send an MP3 consisting of 1 million bytes (1MB)? Explain how you computed your answer.

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)?

At what time (t=?) node B receives the frame in full (i.e. the last bit)? b. After node B receives the frame in full, then it will start sending the frame to node C. Determine the time (t=?) when node C receives the frame in full. c. Suppose at this time node C sends a small acknowledgment back to node A. The transmission time for the acknowledgment is negligible. Calculate at what times (t=?) the acknowledgment arrives at nodes B and A. d.

6. Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b-bits) connection retrieves a 250 KB (B-bytes) web page from a server in Tokyo, where the page references three images of 500 KB each.

Approximately how long does it take for the page (including images) to appear on the user's screen, assuming non-persistent HTTP using a single connection at a time?
