1.4-5 Computing Propagation Delay. Consider the network shown in the figure below, with three links, each with the specified transmission rate and link length. Assume the length of a packet is 8000 bits. The speed of light propagation delay on each link is 3x10^8 m/sec What is the propagation delay at (along) link 2? +Link 1 Link 2 Link 3 Transmission rate: 10 Mbps Link Length: 2 km Transmission rate: 100 Mbps Link Length: 1 km Transmission rate: 100 Mbps Link Length: 1000 km Q Select one: a. .33 secs b. .0033 secs c. 3 x 10^8 secs d. 3 secs 1.4-10 Computing utilization (3). 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) Your answer: The utilization of client link is: [A] R-300 M 90 Mpa 1.4-4 Computing Packet Transmission Delay (3).
