The following picture shows four routers, A,B,C,D. Packets travel from A and B to D. All routers including C operate in FIFO order. If two packets arrive at C at the same time, give priority to packets from A. A Assume that packets of size L = 1 Mbit travel from A and B to D. Transmission Rate: B 1 2 3 From A to C: R=40 Mbps (Mbits/sec) From B to C: R = 30 Mbps From C to D: R = 20 Mbps Propagation Delay. From A to C: 10 ms From B to C: 5 ms From C to D: 10 ms Calculate the time each packet arrives and leaves the routers in milliseconds by filling the tables below. In part 1 there are no transmissions from router B. To solve this problem you will need to plug the number that corresponds to your @ sign. The @sign is based on your last name and can be found under Files-> HW1- >AtSignsBaseOn Your Last Name.xlsx Part 1 Packet Packet 1 Packet 2 Packet 3 Packet 4 Packet 5 Packet 6 Arrives at A 10 0 @ In part 2 both routers A and B transmit packets towards C.
