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 mIs, 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 .5, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on transmission rate?
