I work with something that alleges to compress the ISO OSI 7-layer model into somewhat fewer layers. For all it avoids some complexities of the OSI model, I still don't believe that the (descriptive, informative) text of what I work with is accurate. I just tell folks to ignore it and, in-house, we use different terminology for the troublesome layers.
Is there a successor?
What I am reminded of more than anything else, is the sad eluctability of Asimov's so-called Three Laws of Robotics.
What we witness in both instances is an attempt to wrap words around ideas and concepts that have grown beyond them.
Not that I am aware of. Not until we can come up with some kind of sub-space quantum networking. Maybe they could call it "aether-net". ;-)
