6. Consider two hosts, A and B, connected by a single link with a rate of Rbps. Suppose that the two hosts are separated by m metres, and suppose the propagation speed along that link is s metres per second. Host A wants to send a packet of size L bits to Host B. a) Express the propagation delay, dprop, in terms of m and s. b) Determine the transmission time, dtrans, in terms of L and R. c) Ignoring processing and queueing delays, formulate an expression for the total end-to-end delay. d) Suppose Host A beings transmitting at time t=0. At time t=dtrans, where is the last bit of the packet? e) Suppose dprop is greater than dtrans. At time t=dtrans, where is the first bit of the packet? f) Suppose dprop is less than dtrans. At time t=dcrans, where is the first bit of the packet? g) Suppose s=2.5x108 m/s, L=120 bits, and R=56Kbps. Find the distance, m, so that dprop=dtrans
