GATE | GATE 2017 MOCK II | Question 62
Consider the following two statements:
Statement 1: Stop and Wait protocol is preferred for LANs compared to WANs
Statement 2: Stop and Wait protocol is good for bursty data transmission.
Which of the above two statements are true?
Both 1 and 2
Neither 1 nor 2
Efficiency of Stop and Wait is given by, E= 1/(1 +(2*d*B)/v*L), link speed(v) and Bandwidth (B) are fixed . Thus only variable terms are packet length(L) and distance(d) Cleary, E decreases with increase in d . And E will increase with increase in L .
Hence Stop and Wait is suitable for LANs and bursty data.
