Users need high speed and low latency transmission for new applications. Since Ethernet is the dominant LAN technology, service providers wish to offer new Ethernet services as Layer 2 Virtual Private Network (L2VPN), to meet the requirements of these applications. MultiProtocol Label Switching (MPLS) is one of the most suitable technologies to deploy L3VPN and can also be used to realize L2VPN. Ethernet technology has reached the ability to meet MAN and WAN requirements. This article presents a review of both Ethernet and MPLS technologies to deploy L2VPN and compares both approaches.
