The article begins with a misunderstanding.
The semantic symmetry of the OSI layers is clearly an 'interaction': there is a computer talking to another computer. The stack diagram is obviously only considering a single object, a system. Would not be surprising that should we introduce the 'user' as the peer to the system that we can in fact derive a similar symmetry in layers. Yes, the user side of the layers would be mostly logical 'organizational' concerns.
- edw 7y agoI disagree. The author's point is that if you have a network connection, you can view it as: * A medium with a series of photons or EM waves propagating in one or both directions. * An exchange of packets between two boxes. * … * A conversation between two applications. It's the all the same thing, but it's an increasingly holistic or reductive view of that one thing as you take the thing in from the perspective from increasing or decreasing layers of the OSI stack.
