Paper Abstract

Continued evolution of consumer broadband services such as digital video and digital multimedia has placed renewed emphasis on the need for network solutions to the broadband connectivity challenge. Although still important to architectural planners, connection oriented broadband services based on ISDN concepts must now compete with a wider array of broadcast and highly asymmetrical services for bandwidth on the network. For network operators, the business imperative is to identify and execute a network rebuild plan that will meet the capacity and flexibility needs of these services and compete with the inevitable alternate paths into the home. This paper focuses on some of the key issues facing broadband network planners as they search for the best architecture to meet the business and operations goals in their segment of the market. It will be apparent that no single optimum solution exists for all deployment scenarios, emphasizing the need for flexible and modular sources (such as servers) and network interfaces (such as set tops) which preserve the value of content, the ultimate driver in this round of network revolution.
