a) Complete the traffic table in Figure 3-13. b) In Figure 3-12, add 392 Mbps of traffic for Seattle-Ogden communication. Using a picture like the one in the figure, show your work. c) Do it again with a traffic table. d) In Figure 3-10, remove the link between Q and R but add a link between Q and S. Using a picture, calculate requirements, showing your work. (Do not add the 392 Mbps in Part a.) e) Now use a traffic table to do the calculations. f) If you have 10 sites connected by seven transmission links, how many rows of traffic data will you have in your traffic table? g) How many columns?
