"A company wants to connect two offices, located in Memphis, Tennessee, and Laramie, Wyoming. The offices need to transfer data at 512 kbps. Which is the less expensive solution: a T-1 connection or a frame relay connection? What happens if an office in Baton Rouge, Louisiana, also must be connected to both Memphis and Laramie at a rate of 512 kbps? Which solution is cheaper now? How about considering an MPLS over IP solution or a form of long-haul Ethernet?"
