Suppose two hosts, a and b are separated by 100,000 kilometers and are connected by a direct link of r = 2 mbps. suppose the propagation speed over the link is 2*108 meters/sec. consider sending a file of 800,000 bits from host a to host b.
a. [20 pts] suppose the file is sent continuously as one big message. how long does it take to send the file, assuming it is sent continuously?
b. [20 pts] suppose now the file is broken up into 40 packets with each packet containing 20,000 bits. suppose that each packet is acknowledged by the receiver and the transmission time of an acknowledgement packet is negligible. finally, assume that the sender cannot send a packet until the preceding one is acknowledged. how long does it take to send the file?
