What is the difference between an encryption protocol and an encryption standard? What is the difference between an encryption protocol and an encryption standard?

Am I missing something here? Or are they in fact two different concepts altogether?
A protocol is a standard, in the sense that multiple parties agree to use it (as is required for a communication protocol). However a standard-standard is very widely used and has some kind of official backing. Examples of standard-standards would be Data Encryption Standard, Advanced Encryption Standard, and Internet Protocol.
