Multi-Protocol Label Switching (MPLS) works great for getting Internet Protocol (IP) traffic to move reliably over Asynchronous Transfer Mode (ATM) links, particularly when there's a strict Quality of Service (QoS) requirement or a probable need to scale up. Vivek Alwayn, an experienced CCIE who helps service providers implement MPLS for a living, shares his considerable knowledge of MPLS in Advanced MPLS Design and Implementation. After a brief introduction to MPLS--it should be more of a refresher, really, for people who already know what the technology is about--Alwayn brings out scores of details that define how MPLS works, and how it can be made to work better. His best technique is to present a scenario, declare some design goals for it, and proceed to explain how to achieve those goals. Reading these case studies is really enjoyable from an engineering perspective (even if yours is not a Cisco shop), and they feature enough step-by-step instructions for the IOS command line to never leave you guessing about how to translate the approach to your own equipment. In addition to solving model problems, Alwayn takes time to explain why MPLS works the way it does. In lots of cases, this means calculations. He shows how LCNs are allocated to port groups, how link metrics are evaluated to yield desirable and undesirable results, and how Permanent Virtual Circuits (PVCs) and Label Virtual Circuits (LVCs) are carved out of a port. He's also generous with configuration listings. In a typical exercise, he'll show complete configurations for all routers involved, even if there are eight or nine of them. --David Wall Topics covered: Multi-Protocol Label Switching (MPLS) for people who already have a handle on what it's for and want to use it on their service provider networks and corporate backbones. With lots of command detail and configuration specifics (which are particular to Cisco Systems routers) and engineering discussions (which are not), the author explains how to implement MPLS for Virtual Private Networks (VPNs) over both Internet Protocol (IP) and Asynchronous Transfer Mode (ATM). Beyond that, there is coverage of traffic engineering, Quality of Service (QoS), and migration. An in-depth guide to understanding advanced MPLS implementation, including packet-based VPNs, ATM-based VPNs, traffic engineering, and quality of service Advanced MPLS Design and Implementation enables you to: - Understand MPLS through a detailed analysis of MPLS architecture and operation
- Design and implement packet-based MPLS Virtual Private Networks (VPNs) using label switching routers (LSRs)
- Design and implement ATM-based MPLS VPNs using WAN-switched ATM LSRs
- Implement MPLS traffic engineering on your core network and optimize traffic flows dynamically
- Implement MPLS QoS and provide hard service guarantees with multiple classes of service
- Acquire practical design and implementation knowledge of real-world MPLS VPNs, TE, and QoS through case studies and configuration examples
Multiprotocol Label Switching (MPLS) is a highly scalable, high-performance forwarding technology that has multiple applications in the service provider and enterprise environment. This book is intended for internetwork engineers and administrators who are responsible for designing, implementing, and supporting service provider or enterprise MPLS backbone networks. It contains a broad range of technical details on MPLS and its associated protocols, packet-based MPLS, ATM-based MPLS, MPLS traffic engineering, MPLS QoS, MPLS design, and advanced MPLS architectures. This book contains MPLS theory, design, configuration, and various case studies. Use this book as a reference and guide for designing, implementing, and supporting an MPLS network. Even if you're not using Cisco(r) equipment, this book can increase your awareness and understanding of MPLS technology as well as provide you with detailed design concepts and rules for building scalable MPLS networks. Advanced MPLS Design and Implementation is your guide to understanding, designing, and implementing MPLS VPNs, WAN-switched MPLS VPNs, MPLS traffic engineering, and MPLS QoS.
