PacketCable ImplementationDesign, provision, configure, manage, and secure tomorrow's high-value PacketCable networksJeff Riddel, CCIE® No. 12798PacketCable networks use IP technology to enable a wide range of multimedia services, from IP telephony to interactive gaming and beyond. Because PacketCable-based business and residential services are central to the cable industry's strategy for growth, the industry's need for PacketCable expertise is expected to increase dramatically.PacketCable Implementation is the first complete primer on PacketCable network design, provisioning, configuration, management, and security. Drawing on consulting experience with every leading cable operator, Jeff Riddel presents real-world case studies, sample network designs, configurations, and practical tips for all facets of PacketCable planning and deployment.This book's end-to-end coverage has been designed for cable engineers and networking professionals with widely diverse backgrounds and experience. Topics covered include PacketCable specifications and functional components, multimedia terminal adapters (MTA) provisioning, call signaling, media streaming, quality of service (QoS), event messaging, security, and much more. Every chapter contains tables and charts that serve as quick, easy references to key points. Each chapter closes with a summary and chapter review questions designed to help you assess and deepen your understanding.PacketCable Implementation brings together everything you need to know about cable networking to service delivery.Jeff Riddel, CCIE® No. 12798, is a network consulting engineer on the Cisco® Broadband Advanced Services team. There, he has consulted with all major U.S. MSOs, including Charter Communications, Comcast, AT&T, and Time Warner Cable. Riddel has represented Cisco in PacketCable interoperability testing at CableLabs in Louisville, Colorado. He holds a master's in electrical engineering from the Georgia Institute of Technology.
