Explain how the congestion window (CW) in the TCP protocol is computed in

comparison with the advertised window in flow control. [1 mark].

b. Describe the set-up of the congestion windows with the two different types of

TCP TAHOE and TCP RENO. Describe when and how the congestion

window CW is reset with the two different approaches. [2 marks].

c. Assume that TCP TAHOE is implemented. Consider the flat horizontal lines

recorded in a diagram CW (KB) over time (sec). Why do they happen and

what causes them? [2 marks]

d. Describe two situations when slow start occurs during a TCP connection and

how the congestion window CW is reset in each case [2 marks].

e. With the same network configuration in c) Why packet losses during a normal

timeout could be much more numerous during the start of the transmission? Give a numerical example assuming a specific capacity of the link and an initial value of the CW that can be successfully transmitted from the initial time t0.
