Suppose that R = 1 Gbps and Rc is 300 Mbps and Rs is 200 Mbps. Assuming that the servers are sending at their maximum rate possible, enter the link utilization of the shared link, whose rate is R, below. Enter your answer as a decimal, of the form 1.00 (if the utilization is 1, or 0.xx if the utilization is less than 1, rounded to the closest xx).
Assume a 10Mbps Ethernet has two nodes, A and B, connected by a 360m cable with threerepeaters in between, and they each have one frame of 1,024 bits to send to each other. Further assumethat the signal propagation speed across the cable is 2*10^8 m/sec, CSMA/CD uses back-off intervals ofmultiples of 512 bits, and each repeater will insert a store-and-forward delay equivalent to 20-bittransmission time. At time t=0, both A and B attempt to transmit. After the first collision, A draws K = 0and B draws K = 1 in the exponential back-off protocol after sending the 48bits jam signal. a. What is the one-way propagation delay (including all repeater delays) between A and B inseconds? At what time is A's packet completely delivered at B? b. Now suppose that only A has a packet to send and that the repeaters are replaced with switches.Suppose that each switch has an 8-bit processing delay in addition to a store-and-forward delay.At what time, in seconds, is A's packet delivered at B?

This elementary problem begins to explore propagation delay andtransmission delay, two central concepts in data networking. Consider two hosts, Aand B, connected by a single link of rate R bps. Suppose that the two hosts areseparated by m meters, and suppose the propagation speed along the link is smeters/sec. Host A is to send a packet of size L bits to Host B. g. Suppose ? = 2.5?108, L=1500 bytes, and R=10 Mbps. Find the distance m sothat ????? equals ??????.
Consider the scenario shown below, with four different servers connected to four different clients over four three-hop paths. The four pairs share a common middle hop with a transmission capacity of R = 300 Mbps. The four links from the servers to the shared link have a transmission capacity of RS = 50 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of RC = 90 Mbps. Assuming that the servers are all sending at their maximum rate possible, what are the link utilizations of the client links (with transmission capacity RC)? Enter your answer in a decimal form of 1.00 (if the utilization is 1) or 0.xx (if the utilization is less than 1, rounded to the closest xx). The utilization of client link is:
