Master ATM implementation on Cisco networks

Asychronous Transfer Mode (ATM), an internationally standardized, integrated solution for all traffic types-voice, data, and video-provides a scalable, high-speed network architecture ideal for today's constantly evolving multimedia technologies and the demands that come with that evolution. With the current convergence of IP and ATM networks and applications, the flexibility of Campus and WAN implementation, and an architecture that provides a perfect fit for the integration of voice and data networks, ATM has established itself as a viable technology for the long term. However, ATM is also one of the least understood networking technologies available today. Cisco ATM Solutions provides the information necessary to understand, design, deploy, and configure multifunctional ATM networks.

Derived in part from the official Cisco instructor-led course, Cisco Campus ATM Solutions, and updated and enhanced with technology advancements and tested lab scenarios, Cisco ATM Solutions provides you with a practical, easy-to-understand explanation of the complex principles of ATM technology and its internetworking methods. Beyond obtaining knowledge for the CCIE(r) lab, this book educates you on ATM concepts that can be applied to any vendor. Cisco ATM Solutions establishes a foundation with a basic understanding of ATM networking concepts and terminology and follows through with a wealth of configuration examples and hands-on scenarios that enable you to master configuration of Cisco ATM router interfaces, LightStream(r) 1010 ATM switches, and LAN Emulation (LANE) services.

Cisco ATM Solutions is your definitive self-study resource for understanding ATM and how to implement it as your networking solution.

  • Master the fundamental concepts of ATM, including the ATM reference model, ATM traffic and network management, LANE, and MPOA
  • Learn the functionality and implementation of ATM-associated features by Cisco ATM edge devices with a focus on ATM interfaces, circuit emulation services, multiprotocol encapsulation, Classical IP and ARP over ATM, NHRP, and LANE and MPOA implementation
  • Understand how to implement the ATM cloud itself through detailed information on the features, functions, and configuration of Cisco's campus ATM switch-the LightStream 1010
  • Apply the concepts you've learned through a detailed series of labs concentrating on LANE, MPOA, LightStream 1010 configuration, and other ATM-associated features

Cisco Systems(r), Inc., is the leading global supplier of internetworking solutions, including routers, LAN and ATM switches, dial-up access servers, and network management software. The core of this book is a collaboration of multiple authors and experts to develop the ultimate and definitive course in ATM.

Galina Diker Pildush, CCIE #3176, CCSI(tm), is the President and a Senior Consultant at Advanced Communications Experts (ACE), Inc. She provides training and course development for Global Knowledge Network, Inc., the largest Cisco Learning Partner in the world.
