Kurose and Ross Edition 6 Exercise 1 Question R18 (Page No 69)

Question

How long does it take a packet of length 1,000 bytes to propagate over a link of distance 2,500 km, propagation speed 2.5 · 108 m/s, and transmission rate 2 Mbps? More generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on the transmission rate?

Answer 1

$t_{\text{prop}} = \frac{d}{s} = \frac{2500\times {10}^3}{(2.5\times {10}^8)} = 10.00 \text{msec}$
