I came across protocol suite in Internet Protocol suite, and after I searched for it I found:

which explains protocol stack rather than suite.

Could someone please explain what is protocol suite? It doesn't seem to be same as protocol stack!

Did you see this:

The protocol stack is an implementation of a computer networking protocol suite. The terms are often used interchangeably. Strictly speaking, the suite is the definition of the protocols, and the stack is the software implementation of them.


And this:

The Internet protocol suite is the set of communications protocols used for the Internet and similar networks, and generally the most popular protocol stack for wide area networks.

@Naji You have a bucketful of protocols (the suite). You pull a few out to use for your specific implementation (the stack). – user142485 Aug 29 '12 at 14:19
Thanks @user142485 – Naji Aug 29 '12 at 23:46
@user142485 Actually could you expand your answer with a concrete example such as: For a given (real world) suite S, show two (or more) different (real world) implementations. IMO, it would help to understand much better. – Utku Oct 30 '15 at 11:20
