Carriers have offered connectivity services based on traditional TDM, Frame Relay and ATM for many years. However, the cost of operating separate networks to provide each of these services, as well as the need to sell higher bandwidth services than can be offered with these traditional networks, is forcing them to move to newer, more cost effective technologies, namely Ethernet, IP and MPLS.
Ethernet and IP have allowed networks to deliver high bandwidth and new services with greater flexibility, while MPLS has allowed these new services to become more "carrier-class", offering the connection-oriented behavior, quality of service, and reliability normally associated with traditional technologies. Recently, there has been increased interest in Layer 2 MPLS based services, which support LAN and legacy traffic, and are lower cost and simpler to manage.
Virtual Private LAN Service (VPLS) is a fast growing Layer 2 MPLS based service that offers multi-point connectivity making enterprise LANs in multiple sites appear as if they are on the same LAN.
This course provides an in-depth overview of VPLS, how it works, how it can be deployed within a carrier network and what benefits to carrier and user that it provides.
