Network
Overview
The function of the network is to transmit data (such as weather information, stock
prices, or news stories) generated by the various
subscription services
from their
point of origin to an end-user’s output display. This network can be owned by
WavePhore or by another private entity using WavePhore equipment. Requirements
for data handling, communication protocols, security considerations, and other
characteristics vary from one network to another. However, the following
description supplies a generic picture of one of these networks.
Network
Components
The network comprises the following main areas:
•
Network Control Center (NCC)
Gathers and processes incoming data; uplinks data directly to a satellite or
transmits data to another site for uplinking; provides network management
services
•
Access network
Various means by which data arrives at the NCC: from remote sites over wide
area networks as well as through local computers
•
Satellite
Transmits data received from the uplinking source to the receiver
•
IDR V1000
Receives and processes the incoming data; passes the data to the attached output
device, such as a personal computer
