Traffic grooming is the name given to a family of optical network design problems that has attracted significant attention from both academia and industry in the last decade or so. Traffic grooming has grown from a narrow research area to a mainstream requirement for real world practitioners. This book presents the practical motivation, theoretical description, and extant techniques for traffic grooming in optical networks. The description of the various topics of research is authored by leading researchers in this area, and contains comprehensive description of related literature for each area. This book is intended to be a definitive reference and text for traffic grooming both for the practitioner in industry and the student in academia.

The objective of this book is to provide timely and comprehensive coverage of the principles, technology, practice, and future of tra?c grooming in op- cal networks. Tra?c grooming considerations are already shaping new switch designs and standards, including next generation Synchronous Optical N- work/Synchronous Digital Hierarchy (SONET/SDH) and Generic Framing Procedure (GFP), are a?ecting future optical network technologies, and are creating new business opportunities. Yet information on the topic is sc- tered and there is a shortage of technical sources where relevant material can be accessed in a single location. The motivation for this book was to bridge this gap by providing a single authoritative point of reference to the tra?c grooming state of the art. Tra?c grooming is a complex subject, involving a number of interrelated concepts, standards, and technologies. It is also a rapidly growing ?eld of study,makingitdi?cultforasinglebooktocoverallaspectsindetail.Tocope with this scope and complexity, this book provides appropriate background information, followed by an in-depth study of a few key issues and challenges. It has been our intention to bring together a broad range of perspectives from preeminent researchers in both academia and industry. We believe that these multiple, diverse points of view add considerable value and make the contents more interesting to the reader.
