Suppose two hosts, A and B, are separated by
10,000 Ă—M10,000 Ă—đť‘´
kilometres, where M is the month you were born in (M = 1 for January, M = 2 for February, …, M = 12 for December). Hosts A and B and are connected by a direct link with transmission rate R = 5 Mbps. Suppose the propagation speed over the link is 2.5×108 meters/sec.
What is the propagation delay for this link?
Calculate the bandwidth-delay product, defined as transmission rate times the propagation delay: RĂ—dprop.
Consider sending a file of 800,000bits from Host A to Host B. Suppose the file is sent continuously as one large message. What is the maximum number of bits that will be in the link at any given time?
What does the bandwidth-delay product tell us about a link?
