If your company has offices spread out over the country or even the world, and employees within your company need access to a common set of data such as a master customer database, or they frequently send large files back and forth between offices, you really need to look at the advantages of using an MPLS Network to much this process much faster, more productive, and save money at the same time.
You must understand that an MPLS network creates your own private network just within your company. Data traveling over an MPLS network does not touch the public Internet, which therefore makes that data that much more secure and private from the hordes of malware that exist on the public Internet.
An MPLS network is more robust than the old traditional technology such as a point to point line, but offers many more benefits. With a PTP line, each node on the node needed to have the same bandwidth as the node it was connecting to, but with an MPLS network, each node can have whatever bandwidth is right for that node. For example, you could have a T1 MPLS circuit at branch offices, a 10 MB Ethernet MPLS circuit at regional offices, and a 100 MB Ethernet MPLS circuit at your headquarters office so that all nodes can share data and files, in the same manner as a traditional PTP circuit in a hub and spoke network design.
