This document provides an overview to the family of IEEE 802 Standards, defines compliance with the family of IEEE 802 Standards, describes the relationship of the IEEE 802 Standards to the Open Systems Interconnections Basic Reference Model (ISO 7498:1984) and explains the relationship of these standards to the higher layer protocols, and provides a standard for identification of public, private, and standard protocols.
Metro Service Providers are increasingly turning to Multi-Protocol Label Switching (MPLS) to converge disparate networks and services into a unified core, maintain quality, and deliver additional value-added capabilities. MPLS for Metropolitan Area Networks addresses service providers' challenges by demonstrating solutions provided by MPLS features
- The first book on optical OFDM by the leading pioneers in the field - The only book to cover error correction codes for optical OFDM - Gives applications of OFDM to free-space communications, optical access networks, and metro and log haul transports show optical OFDM can be implemented - Contains introductions to signal processing for optical engineers and optical communication fundamentals for wireless engineers This book gives a coherent and comprehensive introduction to the fundamentals of OFDM signal processing, with a distinctive focus on its broad range of applications. It evaluates the architecture, design and performance of a number of OFDM variations, discusses coded OFDM, and gives a detailed study of error correction codes for access networks, 100 Gb/s Ethernet and future optical networks. The emerging applications of optical OFDM, including single-mode fiber transmission, multimode fiber transmission, free space optical systems, and optical access networks are examined, with particular attention paid to passive optical networks, radio-over-fiber, WiMAX and UWB communications. Written by two of the leading contributors to the field, this book will be a unique reference for optical communications engineers and scientists. Students, technical managers and telecom executives seeking to understand this new technology for future-generation optical networks will find the book invaluable. William Shieh is an associate professor and reader in the electrical and electronic engineering department, The University of Melbourne, Australia. He received his M.S. degree in electrical engineering and Ph.D. degree in physics both from University of Southern California. Ivan Djordjevic is an Assistant Professor of Electrical and Computer Engineering at the University of Arizona, Tucson, where he directs the Optical Communications Systems Laboratory (OCSL). His current research interests include optical networks, error control coding, constrained coding, coded modulation, turbo equalization, OFDM applications, and quantum error correction. "This wonderful book is the first one to address the rapidly emerging optical OFDM field. Written by two leading researchers in the field, the book is structured to comprehensively cover any optical OFDM aspect one could possibly think of, from the most fundamental to the most specialized. The book adopts a coherent line of presentation, while striking a thoughtful balance between the various topics, gradually developing the optical-physics and communication-theoretic concepts required for deep comprehension of the topic, eventually treating the multiple optical OFDM methods, variations and applications. In my view this book will remain relevant for many years to come, and will be increasingly accessed by graduate students, accomplished researchers as well as telecommunication engineers and managers keen to attain a perspective on the emerging role of OFDM in the evolution of photonic networks." -- Prof. Moshe Nazarathy, EE Dept., Technion, Israel Institute of Technology - The first book on optical OFDM by the leading pioneers in the field - The only book to cover error correction codes for optical OFDM - Applications of OFDM to free-space communications, optical access networks, and metro and log haul transports show optical OFDM can be implemented - An introduction to signal processing for optical communications - An introduction to optical communication fundamentals for the wireless engineer

The demand for communication networks has increased dramatically in the last few years, creating a need for an intermediate network that operates over a metropolitan area at comparatively high data rates with simple protocols. With some characteristics of local area networks and wide area networks, the metropolitan area network (MAN) technology reflects the best features of both. The motivations for MAN technology include o interconnection of LANs o high-speed services o integrated services. MANs can be used in the following areas: LAN interconnection Filetransfer Distributed processing Remote services Remote login Metropolitan Area Networks provides an introduction to the key concepts of MANs in an easily understood style. Organized into five chapters, this unique book acts as an excellent reference for a beginner as well as for the veteran in the field. Topics include: Introductory and background information about MANs Interworking devices, MAN topologies, and key issues Various popular protocols proposed for MANs Modeling and performance analysis of common MAN topologies Emerging MAN-related technologies such as BISDN, ATM networks, frame relay, cell relay, SONET, and SMDS For a broad understanding of this expanding subject, Metropolitan Area Networks serves as the singular standard in the field.
