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. <p>"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."<br /> —<b>Gary Horn</b>, Director, Enterprise Architecture and Network Security, Advocate Health Care</p> <p>"A thorough and solid publication that reflects Alcatel-Lucent's industry-leading and innovative approaches to Layer 2 Services. An invaluable asset for any network designer/architect."<br /> —<b>Ray Miller, Jr.</b>, Senior Network Engineer, Sting Communications</p>
