The OSI Model Revisited (2023)

&gt; In place of the formal OSI protocols that failed to gain traction, are other standards and protocols such as HTTP, DNS, TCP, and IP, providing the primary link between the conceptual model and logical solutions.<p>It would be interesting&#x2F;instructive to read some expert thought on <i>why</i> OSI &quot;failed to gain traction&quot;. The OSI breakdown has always seemed reasonable enough. Is there there something about scalability requiring a more ruthless quest for simplicity at work here? Is it the security requirements?

Love the diagrams, will be directing people this way as needed.<p>Like the wise page&#x2F;coconut-horse once said, &quot;it&#x27;s only a model&quot;.
