PREFACE

Cable operators (MSOs) provide various types of voice, video, and data services to residential and commercial customers. The number of customers per operator is in the millions while the operator's network consists of equipment from various vendors. Compliance of equipment with international standards becomes a necessity for their interworking. Quality of service becomes a part of the contractual agreement with customers in commercial services.

Operations Support Systems, tools, and procedures for automation developed by the operators play an important role in managing these complex networks. Vendor-developed Network Management Systems (NMSs) and Element Management Systems (EMSs) are not widely used.

This is the first book describing cable networks, services, and their management in greater detail. The book is written by 13 experts in various fields covering network architectures and services, operations, administration, maintenance, provisioning, and troubleshooting (OAMPT) for residential services; network architectures, services, and OAMPT for business services; cloud, software-defined networks (SDN) and virtualization concepts and their applications as part of the future directions of cable networks. Finally, a proposed self-managed network concept is described.

The book begins by describing architecture and services for Data over Cable Service Interface Specification (DOCSIS) 3.0/3.1, Converged Cable Access Platform (CCAP), content distribution networks (CDNs), IP TV, and PacketCable and Wi-Fi for residential services. The book then follows with operational systems and management architectures, service orders, provisioning, fault management, performance management, billing systems and formats, and security for residential services.

Similar to residential services, the book describes architecture and services for Carrier Ethernet, DOCSIS provisioning over Ethernet Passive Optical Networks (EPON-DPoE), EPON Protocol over Coax (EPOC), CCAP, and IP Multimedia Subsystem (IMS) for business services. Following this, operational systems and management architectures, service orders, provisioning, fault management, performance management, billing systems and formats, and security for business services are explained.

As MSO networks and services change rapidly, future directions for cable networks are projected in Chapter 6 by describing cloud services, virtualization, SDN, and a self-managed network concept with their applications. I hope that this book provides guidance to all those involved in designing and operating MSO networks, researchers, and students.

I thank the co-authors who worked diligently to make this book a valuable reference; editors of IEEE Network Management series, Tom Plevyak and Dr. Veli Sahin, who asked me to write a book on cable networks and management, and provided valuable comments during the editing process; Mary Hatcher of John Wiley & Sons who helped greatly throughout the publication process; and Francois PascalRaj of SPi Global and Danielle LaCourciere of John Wiley & Sons who led the production of this book.

1.1 INTRODUCTION

Cable companies (multiple system operators or MSOs) have been offering phone and TV services over copper medium as the basic residential services for a long time. With the proliferation of broadband, fiber, and wireless technologies, fiber is deployed to provide TV, voice, and Internet services (i.e., triple play) while serving rates over cable are increased with new techniques in supporting triple-play services.

MSOs have been providing residential services over coaxial cable using the Data Over Cable Service Interface Specification (DOCSIS) protocol that permits the addition of high-speed data transfer to an existing cable TV (CATV) system in Mbps currently and aims at supporting capacities of at least 10 Gbps downstream and 1 Gbit/s upstream.
