Metro Ethernet

Book Description

The definitive guide to Enterprise and Carrier Metro Ethernet applications

  • Discover the latest developments in metro networking, Ethernet, and MPLS services and what they can do for your organization

  • Learn from the easy-to-read format that enables networking professionals of all levels to understand the concepts

  • Gain from the experience of industry innovator and best-selling Cisco Press author, Sam Halabi, author of Internet Routing Architectures

  • Metro networks will emerge as the next area of growth for the networking industry and will represent a major shift in how data services are offered to businesses and residential customers. The metro has always been a challenging environment for delivering data services because it has been built to handle the stringent reliability and availability needs for voice. Carriers will have to go through fundamental shifts to equip the metro for next-generation data services demanded by enterprise customers and consumers. This is not only a technology shift, but also a shift in the operational and business model that will allow the incumbent carriers to transform the metro to offer enhanced data services.

    Metro Ethernet from Cisco Press looks at the deployment of metro data services from a holistic view. It describes the current metro, which is based on TDM technology, and discusses the drivers and challenges carriers will face in transforming the metro to address data services.

    Metro Ethernet discusses the adoption of metro Ethernet services and how that has led carriers to the delivery of metro data services. With a changing mix of transport technologies, the book then examines current and emerging trends, and delves into the role of virtual private networks (VPN), virtual private local area networks (VLAN), virtual private LAN services (VPLS), traffic engineering, and MPLS and Generalized MPLS (GMPLS).
