An MPLS Circuit is a virtual private network (VPN) for securely connecting two or more locations over the public Internet or a private MPLS VPN network. MPLS circuits are secured through encryption on a customers router, which is known as a CPE based MPLS VPN, or on the MPLS providers network router, which is known as a network-based MPLS VPN .

AT&T Virtual Private Network (AVPN) Service AT&T Virtual Private Network (AVPN) is a network-based IP VPN solution that is enabled by Multiprotocol Label Switching (MPLS). AVPN is the evolutionary successor to the IP services which began with IPeFR/ATM. AVPN service enables Customers to build an application aware, network-based MPLS virtual private network to link locations and Virtual Private LAN Service - Wikipedia Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires.The term 'sites' includes multiplicities of both servers and clients.

EX Series,ACX Series,T Series,M Series,MX Series. A Layer 2 circuit is a point-to-point Layer 2 connection transported using Multiprotocol Label Switching (MPLS) or other tunneling technology on the service provider’s network. A Layer 2 circuit is similar to a circuit cross-connect (CCC), except that multiple virtual circuits (VCs) are transported over a single shared label-switched path

What’s the Difference Between a VPN and a Proxy?

Site-to-Site VPN vs Leased Circuit. The primary issue with site-to-site VPNs is that you need to know when to use them and when to use a leased circuit. As environments grow, they can see a decrease in application performance over the VPN connection, since they all rely on the internet. Azure ExpressRoute - How to create a connection between
