Everyone is talking about MPLS-VPN. However, not many people have a clear perception about MPLS-VPN. Well, this article tries to make a perception about MPLS-VPN for laymen, as it is a very complex process.

What is MPLS VPN?

MPLS or Multiprotocol Label Switching is a method that helps in carrying of data in many advanced networks of telecommunications. It is a method that helps direct any data from a particular network node to another using the shortest possible path label than long network paths. This can help avoid complex lookups in a table for routing. MPLS VPN is the bunch of methods that are used for MPLS to create VPNs or virtual private networks. 

Types of MPLS VPNs deployed 

There are primarily three types of MPLS VPNs used nowadays. They are Layer2, Point-to-point and Layer3.  Layer 2 is also known as virtual private LAN service and is used to route video, audio and AMI traffic between data centres and sub-stations. Point-to-point, also known as pseudowire, uses virtual leased lines to provide point-to-point connectivity from one site to another. Layer 3 VPNs helps service providers participate in Layer 3 routing of customers.

How MPLS VPN helps businesses

  • Fewer WAN or router handling professionals required for the organization - MPLS is operationally easier than managing a bigger routed network. The organization that uses MPLS VPN technology can keep fewer WAN engineers for handling and managing networks. 
There’s no denying fact that MPLS VPN technology has become quite popular and used by the organization as it can help money and makes networking process simpler. Moreover, one can use the technology over the existing one, as it provides connectivity to any network or any channel to any other. This has helped in the evolution of technologies used in Enterprise VoIP or Enterprise telephony. MPLS VPN technology has changed the business scenario with its advanced features and helped many enterprises in better networking and routing management.
