Abstract
A revolution is occurring in the scope and range of information,
communication and education services that will be made available to schools,
libraries, town-halls, clinics and, most importantly, residences. These
services will be provided initially, primarily over hybrid fiber-cable
systems, either by telephone companies or cable companies. The old cable
plant is being upgraded and used in totally new ways.
The topology and physical characteristics of the up-stream channel present
new challenges for efficient channel access. We present a media access
protocol that efficiently transfers data on this channel. A primary goal in
the design was to keep the portion of the protocol resident in the station
as simple as possible. Thus we use centralized control located in the cable
head-end. A station wishing to transmit sends a request to the hear-end
using a contention channel. The head-end acknowledges the request and then
schedules the request, informing the station by means of a grant message
when to transmit.
