Uppgift 31 ur "Problems", kap 3, i Kurose & Ross, andra upplagan.

Consider sending an object of size O = 100 kbytes from server to client. Let S = 536 bytes and RTT = 100 msec. Suppose the transport protocol uses static windows with window size W. (See section 3.7.2.)

1. For a transmission rate of 28 kbps, determine the minimum possible latency. Determine the minimum window size that achieves this latency.
2. Repeat for 100 kbps.
3. Repeat for 1 Mbps.
4. Repeat for 10 Mbps.

Uppgift 33 ur "Problems", kap 3, i Kurose & Ross, andra upplagan.

Consider the case RTT = 1 second and O = 100 kbytes. Prepare a chart (similar to the charts in section 3.7.2) that compares the minimum latency (O/R = 2RTT) with the latency with slow start for R = 28 kbps, 100 kbps, 1 Mbps, and 10 Mbps.
