From OSI Layers to Evolution Layers via UNIX



Undoubtedly the OSI model is no help for beginners of Networking, it does not tell you how to play with network technology. Due to lack of any other didactic means it has became the de facto introductory material until books began to appear around the early 90s.


Its strong point is that it pushed the case for standards at times where the big computer makers like DEC and IBM battled to establish their own proprietary computer-network technology like DNA and SNA correspondingly. Amongst the positive achievements of OSI are ASN.1, a data structure modelling tool and the fist ever go at fixing Networking concepts.



In this battle for the network the other opposite was the telecommunication industry which did push for standards but also their own agenda, its main feature was to obstruct competition in this new world of computer-networks. The most powerful weapon, in fact a Trojan horse, was UNIX.

Etching a course following the Internet Wave as a developer and part-time theorist


In the year 1999 I have two results of my own NET8 and Internet Systematics. Although quite esoteric these terms map to real networking issues. The need of Network Theory, Fundamentals of Networking, Origin of big problems of Internet, Innovation pattern, Architectural issues.
