MPLS VPN is A Reliable Service across Multiple Sites

VPLS, MPLS VPNs, MPLS and VPNs are some of the often used interchangeably terms but among each other due to the multitudinous words that are used by the vendors and marketers to describe the same service with.

Multiprotocol Label Switching (MPLS)is a standards-based technology that is used to speed up the delivery of network packets over multiple protocols – such as Asynchronous Transport Mode (ATM), Internet Protocol (IP), and frame relay network protocols. A virtual private network (VPN) uses shared public telecom infrastructures, such as the Internet, to provide secure access to remote offices and its users in a cheaper way other than an owned or leased line.

VPNs are secure because they use the tunnelling protocols and procedures such as Layer Two Tunnelling Protocol often known as L2TP. MPLS VPN is a VPN that is built on top of a MPLS network that is usually done from a service provider to deliver connectivity between enterprise office locations. The terms "MPLS IP VPN," "MPLS VPN" and "MPLS-based VPN" can be used synonymously.

MPLS VPN is a family of methods that is used for harnessing the power of multiprotocol label switching (MPLS) to create virtual private networks or VPNs. MPLS VPN and the various VPN Solutions give network engineers the flexibility to route and transport several types of network traffics using the technologies of a MPLS backbone.

Before this technology was put to use, enterprises were restricted to limited wide area network (WAN) connectivity options. The problem with these was that they were usually very expensive, complex and inflexible to manage for both the service providers and the enterprises. MPLS usage began over a decade ago as a way to allow enterprises to create end-to-end circuits across any type of transport medium using any available WAN technology.

MPLS VPN is A Reliable Service across Multiple Sites as the MPLS VPN backbone always uses the Border Gateway Protocol (BGP) as its routing protocol. Almost any other routing protocol can be used to connect our sites with the MPLS VPN backbone, but many service providers limit the choices to static routing and BGP. Each of the edge routers peers with just one router that is the PE-router and we get an optimum any-to-any connectivity between your sites regardless of your network topology. Through this, MPLS VPN makes sure that all the data packets that are being send reach the specified service provider’s and the service receiver’s network only. While transferring any kind of information from one site to another, the information is divided into smaller units that are called as data packets. This is the form in which information travels through all the networks.

MPN VPN poses as an important aspect as the security levels maintained are often very high especially considering the fact that information being sent in the form of data packets reaches its destination only through the dedicated network where the information that is travelling through multiple site links is not at risk. Thus we can easily say that MPLS VPN is one of the well.
