Computer Networks

Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B. a. Express the propagation delay, damep, in terms of m and s. (3 Points) b. Determine the transmission time of the packet, drans, in terms of L and R. (3 Points) 4. Ignoring processing and queuing delays, obtain an expression for the end-to-end delay. (3 Points) c. d. S t-0. At timet dtrns, where is use Host A begins to transmit the packet at time the last bit of the packet? (3 Points) Suppose dprop is less than dtrans. At time t-dtrans, where is the first bit of the packet? (3 Points) e. f Supposedy is greater than d. At timet-dm, where is the first bit of the packet? (3 Points)
