A guide to designing and implementing VPLS services over an IP/MPLS switched service provider backbone

Today's communication providers are looking for convenience, simplicity, and flexible bandwidth across wide area networks-but with the quality of service and control that is critical for business networking applications like video, voice and data. Carrier Ethernet VPN services based on VPLS makes this a reality. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer.

Virtual Private LAN Services (VPLS) is quickly becoming the number one choice for many enterprises and service providers to deploy data communication networks. Alcatel-Lucent VPLS solution enables service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable QoS characteristics of MPLS.

This guide is a must read for any network engineer interested in IP/MPLS technologies and Carrier Ethernet Layer 2 VPN services. Discover what it takes to optimize an IP/MPLS-based VPN network's reliability, performance, and flexibility. Learn about the core components of an IP/MPLS VPN Service Architecture, and enhance your network with new service-carrying IP/MPLS technologies such as RSVP-TE, Fast Reroute, and secondary LSP. Get a thorough knowledge of the two core Ethernet Layer 2 VPN services: Virtual Private LAN Service (VPLS) and Virtual Leased Line (VLL). Explore advanced topics such as Service Resiliency, BGP Auto-discovery, Provider Backbone Bridging, and OAM for VPLS and learn how to implement them in your network.

"An extremely valuable tool for anyone involved in the design, operation, and maintenance of MPLS-based networks. The reader will walk away with a clear and practical understanding of all aspects of the complexities associated with MPLS network operations. I highly recommend that this text be part of any MPLS network engineer's library."
Gary Horn, Director, Enterprise Architecture and Network Security, Advocate Health Care
