Introduction to Carrier Ethernet VPNs: Understanding the Alternative

There are a wide range of VPN technologies available. MPLS-based VPNs are the most prevalent technology types used today, with many based on the use of Ethernet transport to provide high-speed communications. This paper describes the various MPLS-based Ethernet VPN services and technologies which Juniper Networks supports. These include Juniper's best-in-class VPN implementations, as well as alternatives which provide interoperability with deployed non-Juniper products. This paper is intended for marketing managers seeking to understand Ethernet VPN options, as well as technical managers seeking an overview of their technical alternatives.
