An MPLS VPN service is a virtual private network (VPN) for securely connecting two or more locations over the public Internet or a private MPLS VPN network. MPLS VPN networks are secured through encryption on a customers router, which is known as a CPE based MPLS VPN, or on the MPLS VPN providers network router, which is known as a network-based MPLS VPN. MPLS VPN services are typically provisioned over Internet T1 lines or a private MPLS circuit, higher bandwidth speeds are offered as well (MPLS Ethernet, NxT1, DS3), with options for managed MPLS VPN services. An MPLS IP VPN provides class of service (CoS) by utilizing MPLS VPN technology to prioritize and route time-sensitive data based on application. MPLS IP VPN services are used by businesses to provide reliable, secure, MPLS VPN service for applications including credit card processing, file sharing, data backup, MPLS VOIP, or remote access. MPLS VPN’s can also be configured by most MPLS VPN providers to carry voice, Internet, and IP VPN services together as an Integrated MPLS T1 line. MPLS IP VPN services are also known as an MPLS WAN, MPLS Circuit, MPLS Network, VPN T1, or MPLS T1.
