On-Demand Network Transport Architecture (1996)
By Louis D. Williamson, Time Warner Cable
The paper explores the architectural requirements to support an on-demand interactive digital network within the hierarchy of a hybrid fiber coax network. A traditional entertainment network is fundamentally a broadcast network. As new services, such as telephony, high speed modems and interactive televisions are introduced, can the same physical transport support them? What are the differences in their requirements? What are the behavioral differences of a broadcast network versus an on-demand network? The paper reviews the current distribution hubmaster hub based HFC network and discusses available options to accommodate new digital switched services.
