This paper is about a new technology, MPLS VPN, that is being offered by service providers to compete with Frame Relay and ATM networks. When a company wants to connect its geographically different sites they don't have to purchase a Frame Relay circuit, or purchase an ATM circuit, or lease a dedicated telco line. They can now go to their Internet service provider and purchase a MPLS VPN to connect their geographically different sites. This paper will give a basic understanding of how a MPLS VPN works.
