OFFICIAL PROTOCOLS This RFC identifies the documents specifying the official protocols used in the Internet. Annotations identify any revisions or changes planned. To first order, the official protocols are those in the "Internet Protocol Transition Workbook " (IPTW) dated March 1982. There are several protocols in use that are not in the IPTW. A few of the protocols in the IPTW have been revised. Notably, the mail protocols have been revised and issued as a volume titled "Internet Mail Protocols " dated November 1982. Telnet and the most useful option protocols were issued by the NIC in a booklet entitled "Internet Telnet Protocol and Options " (ITP), dated June 1983. Some protocols have not been revised for many years, these are found in the old "ARPANET Protocol Handbook " (APH) dated January 1978. There is also a volume of protocol related information called the "Internet Protocol Implementers Guide " (IPIG) dated August 1982. This document is organized as a sketchy outline. The entries are protocols (e.g., Transmission Control Protocol). In each entry there are notes on status, specification, comments, other references, dependencies, and contact. The status is one of: required, recommended, elective, or experimental. The specification identifies the protocol defining documents. The comments describe any differences from the specification or problems with the protocol. The other references identify documents that comment on or expand on the protocol. The dependencies indicate what other protocols are called upon by this protocol. The contact indicates a person who can answer questions about the protocol
