I currently have a frame relay network with 3 locations. Each has a T1 Port with a 512 CIR and PVC's between headquarters and the two remote offices. I am looking at replacing this with higher bandwidth and potentially save money as well. I have an offering of two dedicated point-to-point T1 circuits between my headquarters and the two remote sites which is about 1/2 the cost of my existing Frame network. I also have a MPLS vendor claiming that his solution provides better performance than what I would be getting from either my frame network or my proposed point-to-point. The MPLS solution is cheaper than the Frame, but more than the dedicated T1's.
I don't know very much about MPLS, but I have trouble understanding how I can get better performance from this than the 2 separate dedicated T1's. With either the Frame or MPLS, I would have one T1 at headquarters sharing the bandwidth going to two remote sites. With the dedicated circuits, I would have two full dedicated T1's. We will not be routing anything other than IP network traffic.
