Clinton National was using strictly an MPLS T1 network between 9 branch locations. No redundancy or ability to transfer large amounts of data to offsite locations. Large data transfer had to be done strictly by tapes manually transferred between locations.
Ever increasing costs of local loop Telco lines to attach from a branch into their MPLS cloud prompted Clinton National to look for alternative ways to make this connection. They also wanted a method for branch connectivity in the event the MPLS circuit went down, as well as replicate/transfer large amounts of data between data centres.
