OSI Model / Simplified (Network Training)

The OSI (Open Systems Interconnect) Model has existed since approximately 1995 as the only ‘official model’ for teaching networking concepts. This model has become an inadequate model to describe ‘modern’ networking concepts because modern everyday networking processes have moved way beyond what the OSI Model was originally developed to explain. For instance, the OSI Model tries to help students understand the difference between multiple network protocols like TCP/IP (IPv4), Apple Talk, Net Bios, and different transports like Token Ring, FDDI, and Ethernet. Today, there is only one (1) network protocol – IP (with variations IPv4 and IPv6), and one (1) primary transport – Ethernet. Therefore, a more simplified model (Network Simple) is needed to explain currently ‘established’ networking concepts and processes not originally included with the OSI Model.

The concept of USER ID’s, Authentication, and Authorization are not included in the OSI Models description of networking. Yet students that are learning networking are constantly challenged to understand this and other concepts without an adequate model to place these network functions into their proper perspective. Therefore we put forth the below diagram to help students understand networking with a modern perspective (Network Simple, Archetype Model).

Model Legend (diagram below):

OSI Model = (Open Systems Interconnect) developed by the ISO (International Standards Organization). Traditionally used to teach networking concepts. This model has become a somewhat outdated and overly complicated method used to help students understand a functioning network (internet) and its processes.

Network Simple = This model’s perspective is based upon a greatly simplified version of the OSI Model with supporting insight into important networking functions/concepts not directly/simply (explained) by the OSI Model (alone).

Archetype Model = This model holds the perspective that ‘nothing is new’, and that modern networking (internet) is based upon existing communication systems that have been, and/or are currently in existence.  Thus the Archetype Model tries to provide a method to understanding what appears to be how networks (internet) follow the “natural laws of communication”.

NOTE: The Network Simple model is used as a bridge to understanding the Archetype Model thus helping students grasp concepts of networking in an easier to understand manner than just through the OSI Model alone.
