Peterson Davie 2.36a

Question

(Figure 2.37)

Suppose $A$ is connected to $B$ via an intermediate router $R$, as shown in Figure 2.37. The $A - R$ and $R - B$ links each accept and transmit only one packet per second in each direction (so two packets take $2$ seconds), and the two directions transmit independently. Assume $A$ sends to $B$ using the sliding window protocol with $SWS = 4$.

(a) For Time = $0,1,2,3,4,5$, state what packets arrive at and leave each node, or label them on a timeline.

Answer 1

            A                  R                 B

t=0      1

t=1      2                    1

t=2      3                    2                  1

t=3      4                    3                  2

t=4                            4                  3

t=5                                                4
