8. (12 pts) Consider a 10Mbps with a minimum packet size of 64KB. a. how long does it take to send such a packet? Assume K-10 2018 Kevin B Long, Kurose and Ross Page 3 of S Assume that the distance between the sender and the receiver is 12,000 km and that light travels at 2.5 x 108 m/s. b. What are the propagation and transmission times for a 2.5KB file if the bandwidth of the network is 1 Gbps? Transmission timems Propagation time:ms What if the file is 10MB, the network is IMbps, and it again is 12,000km? c. Transmission time ms Propagation time: ms
