Concept
GeoNet
Résumé
GeoNet was an early international on-line services network built using microcomputers. Based on software developed in Germany by GeoNet Systems GmbH in the early 1980s, and completed in the early 1990s, it was one of the first networks to offer a comprehensive on-line services platform, and was early to market with a number of innovations. Unlike other "mailbox" systems at the time, GeoNet had a user-friendly command interface and made extensive use of distributed processing technology.
GeoNet became an important force in the European market within 15 months of introducing its first system in the early 1980s, and by 1986 had an installed base of some 25 systems in 8 countries. By the early 1990s GeoNet systems had been established in Austria, France, Germany, Guatemala, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, Switzerland, UK, USA and USSR. Apart from the Austrian PTT and An Post in Ireland, most of the operators were independent private companies.
GeoNet systems were strongly interconnected using a proprietary pre-X.400 protocol, called "InterMail". The so-called "GeoMail" network constituted a worldwide “private domain”, later interconnected with other public and private domains through X.400.
Later versions of GeoNet software ran under OpenVMS on DEC hardware. The largest installations ran on Alpha clusters. GeoNet operated centralised system monitoring and maintenance from Germany.
Some of the many innovative features of the GeoNet systems:
Cross-system accounting and clearing: the systems were able to bill for many on-line activities, but also had a built-in micropayment clearing system whereby users of one system could use services offered on another and be billed accordingly.
Unified database front end: the GeoNet philosophy was to offer users a "one-stop-shop" for on-line services. Users could access a wide range of remote on-line databases using a sophisticated gateway called Intelligent Interface, developed with a research grant from the European Commission.
