xxii Foreword
Introduction
How This Book Came About??¦
Even as the value of Ethernet beyond the LAN was being widely recognized, the major
challenge was the lack of clarity as to what this ???Carrier Ethernet??? entailed, and more
generally, a lack of understanding of the delivery solutions over the diverse network
infrastructures used by Service Providers. This was to a large extent understandable
given a) the infancy of the field, b) the numerous network solutions that could be used,
and c) the fact that these solutions are generally very different from each other in
terms of the technology, focus, relevance, and extent of optimization needed to deliver
Ethernet services.
This book attempts to mitigate that hurdle??”and in its own small way, accelerate the
deployment of Carrier Ethernet services??”by providing a comprehensive, practical, and
insightful description of Carrier Ethernet and the different network solutions that can,
and are, being employed currently.
