Overview

Facilitating high data transfers over long distances at a reasonable cost, Carrier Ethernet is solidifying its fundamental position as the core of next-generation networks. Since it first dazzled the IT world 40 years ago with its ability to move data over local networks, Ethernet has dramatically evolved in both form and function. And now, Carrier Ethernet, flexing its multi-gigabit muscle, is rapidly emerging as the undisputed technology of choice.

As engaging as it is comprehensive, this volume—

  • Examines the differences between the so-called flavors of Ethernet
  • Provides refreshers on virtual LANs (VLANs), virtual private networks (VPNs), and Multi-Protocol Label Switching (MPLS)
  • Details Carrier advantages over other modalities with regard to network performance
  • Delves into Service Level Agreements, including ways to obtain a quality of service for the movement of voice and real-time video, as well as the creation of VLANs to facilitate the movement of data
  • Describes various services that can be enabled over an Ethernet infrastructure

All You Need to Know about this Carrier-Class System

Ensuring seamless migration to Carrier Ethernet from existing technologies, as well as integration with emerging services, this text provides readers with the expert guidance needed to make full use of Ethernet technology, both now and into the future.

    Perfect for carrier Gigabit Ethernet provisioning staff.

    Ever wondered why you make the selections you do when making those connections? You know you must be, in some way, affecting the Ethernet frame format right? Well this reference provides the answers by providing a complete desription of those fields including in depth discussion of 801.1q, QinQ and Provider Bridging, as well as a review of the technology. You could be excused for thinking that this reference was written by the very vendor of the equipment you are using right now. It is completely relevant to all the operations I currently perform and is up to date.
