As ubiquitous as the OSI model is in the world of network engineering, it occurred to me recently that I could not recall seeing a standard document defining the model referenced even once in all of the books I’ve read. Odd. A little digging turned up a formal definition of the model in the form of ITU recommendation X.200, available for free in PDF format.
If you work in networking, or some networking adjacent field, then you’ve, at the very least, heard of the OSI Model. If you work in networking and haven’t heard of the OSI Model, how did you make it into networking?
In any case, I thought this was interesting. My experience was similar to this posts author. Everything I studied related to the OSI Model, but I don’t recall a reference to how it came about.
