Abstract

This memo describes the current state of standardization of protocols used in the Internet as determined by the Internet Engineering Task Force (IETF). Sections 3.1 - 3.6 contain the lists of protocols in each stage of standardization - Standard, Draft Standard, Proposed Standard, Experimental and Historic. Protocols that are new to this document or have been moved from one protocol level to another, or differ from the previous edition of this document are marked. Informational Request for Comments (RFCs) are not included. This memo lists the current protocols; it is not a complete index to RFCs.

1 Overview

This memo describes the current state of standardization of protocols used in the Internet as determined by the Internet Engineering Task Force (IETF). Sections 3.1 - 3.6 contain the lists of protocols in each stage of standardization - Standard, Draft Standard, Proposed Standard, Experimental and Historic. Protocols that are new to this document or have been moved from one protocol level to another, or differ from the previous edition of this document are marked. Informational Request for Comments (RFCs) are not included. This memo lists the current protocols; it is not a complete index to RFCs.

This memo is published by the RFC Editor in accordance with Section 2.1 of "The Internet Standards Process -- Revision 3", RFC 2026, which specifies the rules and procedures by which all Internet standards are set. This memo is prepared by the RFC Editor for the IESG and IAB. Please see http://www.rfc-editor.org for later updates to this document.
