Protocol Guide, Meaning , Facts, Information and Description
- For the meaning in computer science, see protocol (computing).
- In addition to the meaning below, treaties are sometimes called protocols. The word derives from a Greek phrase meaning "first leaf", referring to the first draft of a treaty.
In international law and international relations, a protocol is a treaty or international agreement that supplements a previous treaty or international agreement. A protocol can amend the previous treaty, or add additional provisions. Parties to the earlier agreement are not required to adopt the protocol; sometimes this is made clearer by calling it an 'optional protocol', especially where many parties to the first agreement do not support the protocol. Some examples: the United Nations Framework Convention on Climate Change (UNFCCC) established a framework for the development of binding greenhouse gas emission limits, while the Kyoto Protocol contained the limits later agreed upon.
By the turn of the twenty-first century the word protocol had also come into wide use in the computer and communications fields; see communications protocol and protocol (computing).
