[ih] A comment on the seven layer model

[touch at strayalpha.com]

Yup - recursive - it's the basis of what I call the Recursive Network Architecture, which is the theory on which the way I taught networking works:

The approach I use is called a “first principles approach to networking”, which ties together info theory, physics, and recursion…
