AT&T MPLS

What really is MPLS?

Multi-Protocol Label Switching, better known as MPLS, is a high- speed highly effective means of transferring data across a network. Often times, with other data carrying technologies data moves across the internet by jumping from endpoint to endpoint. At each of these endpoints the network address is looked up in full in a routing table and then the data moves on to the next endpoint. Multi-Protocol Label Switching works differently. With MPLS each packet of information is given a label. That label outlines the packets route from node to node, start to finish, this eliminates all of the endpoint lookups and speeds the process of information transfer.

MPLS operates at a level between the data link layer, layer two, and the network layer, layer one. For this reason Multi-Protocol Label switching is considered to be layer 2.5 protocol.

What are the benefits of MPLS?

Multi-Protocol Label Switching allows the user to decide which information is most time sensitive. MPLS offers different classes of service. This is a great way for you to insure that secondary communication is held back while time sensitive communication is pushed through at the fastest speed possible. This works because both types of traffic travel over the same link so high priority traffic is actually able to borrow capacity from the less urgent material. MPLS is also able to decide on the best path to send information. Rather than sending everything directly over the shortest path MPLS spreads out communication. This reduces network congestion. Even though the material may be taking a longer route it gets to its destination faster by avoiding congested areas. Additionally, Multi-Protocol Label Switching is scalable. This means that you can get just the right amount of service to meet your business’ specific needs. This cuts down on cost in the end because it frees you from paying for anything you do not need.

Lastly, it is important to note that a key benefit of AT&T MPLS is AT&T itself. When you work with such a widely used company you can count on their sustainability and reputation. AT&T is one of the most reliable telecommunication providers available today. AT&T engineers are constantly working to test and improve their MPLS service. This should give you as a consumer the confidence you need trust AT&T with your communication needs.
