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 for the server links (with transmission capacity RS)? 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)

Host A wants to send a large file to Host B. The path from Host B has three links, of rates R1 = 500 Kbps, R2 = 2Mbps and a.             Assuming no other traffic in the network, what is the throughput for the file transfer.b.            Suppose the file is 4 million bytes. Dividing the file size by   throughput, roughly how long will it take to transfer the file to Host B?Repeat (a) and (b), but now with R2 reduced to 100kbps.

Suppose a number of users share a 4 Mbps link. Also, suppose that each user transmits continuously at 2 Mbps when transmitting, but each user transmits only 20% of the time.When circuit switching is used, how many users can be supported? No explanation is required.

If five devices are connected to the same switch and the network is operating at 1 Gbps, what is the maximum bandwidth for a single device?5 Gbps200 Mbps50 Gbps1 Gbps

7.3-1. Overlapping 802.11 wireless networks (c)Suppose now that A sends messages to B, and C sends messages to D. What is the combined maximum rate at which data messages can flow from A to B and from C to D?Group of answer choices2 messages/slot.1 message/slot.0.5 messages/slot (i.e., 1 message every two slots).0.25 messages/slot (i.e., one message every four slots).
