(Not really.  The abbreviation 'RST' is a "generally accepted" abbreviation in computing to mean reset.)



What bothers me more about the name 'RST_STREAM' is that it's usage in http/2 doesn't match the meaning of the word reset.  For example, here are some of the definitions of 'reset' that a quick search found:



= "cause (a binary device) to enter the state representing the numeral 0." [http://www.oxforddictionaries.com/definition/english/reset]

="to move (something) back to an original place or position" [http://www.merriam-webster.com/dictionary/reset]

="to set again or anew" [http://www.merriam-webster.com/dictionary/reset]

= "to restore (the contents of a register or similar device) in a computer system to zero" [http://dictionary.reference.com/browse/reset]

In other words, the word reset implies that the stream should be reset back to its *original* state (i.e. IDLE), but RST_STREAM immediately takes a stream to its *terminal* state (i.e. CLOSED).

A more appropriate name would be TERMINATE_STREAM (or perhaps close).

Even the definition in Section http://http2.github.io/http2-spec/#RST_STREAM uses the words “terminate” and “close” to describe this frame.
