Reconsider part b of Case 6-4. Use the spreadsheet model developed there to incorporate the following consideration.

An additional concern not considered in Case 6-4 is that the routers at nodes C and F are each already maxed out. If any additional capacity is built into or out of node C or node F, then the routers at these stations must be upgraded. This would cost a total of $2 million at node C or a total of $3 million at node F. Which network segments should be increased in capacity and by how much so as to increase the total capacity of the network enough to transmit the peak requirement of 35 GB/s from the Olympics site (A) to the home studios (G) at the lowest possible cost?
