Freeway Introduction

This manual describes how to install and operate software on your Freeway server.

Before installing the server software, you should familiarize yourself with basic Freeway

concepts as described in this introductory chapter. Then you can proceed to Chapter2

which contains the software installation procedures. Refer to the Glossary for Freeway

terminology and acronyms.

1.1 Freeway Overview

Protogate provides a variety of wide-area network (WAN) connectivity solutions for

real-time financial, defense, telecommunications, and process-control applications.

Protogate’s Freeway server offers flexibility and ease of programming using a variety of

LAN-based server hardware platforms.

Protogate’s Freeway communications servers enable client applications on a local-area

network (LAN) to access specialized WANs through the DLI. The Freeway server can be

any of several models (for example, Freeway 1100/1150, Freeway 1200/1300, Freeway

2000/4000, or Freeway 8000/8800). The Freeway server is user programmable and com-

municates in real time. It provides multiple data links and a variety of network services

to LAN-based clients. Figure 1–1 shows the Freeway configuration.

To maintain high data throughput, Freeway uses a multi-processor architecture to sup-

port the LAN and WAN services. The LAN interface is managed by a single-board com-

puter, called the server processor. It uses the commercially available VxWorks operating

system to provide a full-featured base for the LAN interface and layered services needed

by Freeway.
