(Solved) : Consider Two Hosts B Directly Connected Link 40 000 Km Propagation Speed 25 108 M S Transm Q30985022 . . . .

 

Consider two hosts, A and B, directly connected by a link of40,000 Km, propagation speed 2.5*108 m/s, and transmission rate R=5Mbps. Assume zero queuing delay.

(e) (5 points) Suppose dprop is less than dtrans. At time t=dtrans, where is the first bit of the packet?

(f) (10 points) Calculate the bandwidth-delay product R*dprop.

(g) (10 points) Consider sending a file of 1,200,000 bits fromhost A to host B. Suppose the file is sent continuously as a largemessage. What is the maximum number of bits that will be in thelink at any time? (Hint: the answer shall be the smaller value ofbandwidth-delay product and
