Internet standards are generally proposed and honed by various commitees in public documents across the World Wide Web. These documents are called RFC’s (Request for Comments). For any standard protocol you will find a number of these documents on the Web. Some relevant ones are in the M directory.
The web site http://www.rfc-editor.org
is currently the
best source for finding RFCs.
Another starting place for a search engine; you can find them simply by entering the phrase:-
<protocol> +RFC
into the search engine. When looking up a protocol be aware of two things:-
