MPLS Network...Your Best Choice For A Multi-Site Business Communication Network

Are you familiar with Business Ethernet or MPLS Networks in general? If so, you know that MPLS offers a significantly more cost effective solution for connecting multiple sites than a spider-webbed point-to-point network. The advantages are abundantly clear -- with a point-to-point network, unless you spider-web it so that all nodes can communicate with all other nodes (which is prohibitively expensive), if a link goes down between nodes, then a number of nodes are cut off from your private network until that connection is restored. But with MPLS and the private cloud and intelligent routing it provides, one node being down only affects that particular node, not the other nodes on your private network.

Another advantage of MPLS Networks is that each node can be sized with the appropriate amount of bandwidth. For example, in a point-to-point configuration, if you have a PTP connection between "A" and "B", you must have the same bandwidth at both "A" and "B". But with MPLS you can have an MPLS T1 at node "A", a 50 MB Ethernet MPLS at node "B", a Bonded T1 MPLS at node "C", etc, and it will all work together very nicely.

Like a T1 line or bonded T1 line, you can also have Ethernet MPLS circuits which is generally a much more cost effective option for the same levels of bandwidth on your MPLS network.

Some companies elect to use an enhanced port to allow Internet access and MPLS access on the same circuit. While being a technical reality, the jury is still out on whether or not this makes logical sense from a security standpoint, since without proper safeguards and a secure firewall, having Internet access available on the same circuit that your private MPLS network is operating can represent a security risk, despite the financial advantage of this type of setup.

One thing in particular to note is that MPLS technology is a methodology, and it is NOT a standard. What this means to you is that every carrier implements MPLS differently, and you need to use the SAME carrier at all of your MPLS nodes. While it is theoretically possible to mix and match carriers on your MPLS network, the time, effort, and "technical jury-rigging" is frequently not worth the effort compared to using the same carrier at all of your MPLS nodes.

As long as you are using the same carrier for all nodes, you can mix and match the level of bandwidth at each node according to the type of traffic you expect to have at that node. For example, node A might just be an MPLS T1, while node B might be a 3xT1 bonded MPLS location, node C might be 10 MB Fast Ethernet MPLS, etc. This aspect is significantly different than a point-to-point circuit where the same bandwidth needs to be present at each end of the circuit.
