+ OFFICIAL ARPA-INTERNET PROTOCOLS
+
+
+STATUS OF THIS MEMO
+
+ This memo is an official status report on the protocols used in the
+ ARPA-Internet community. Distribution of this memo is unlimited.
+
+INTRODUCTION
+
+ This RFC identifies the documents specifying the official protocols
+ used in the Internet. Comments indicate 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 Telnet
+ options have been revised and issued as a volume titled "Internet
+ Telnet Protocol and Options" (ITP) dated June 1983. The File
+ Transfer Protocol has been revised most recently as RFC 959 which is
+ not yet included in any collection. 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.
+
+ In particular, the status may be:
+
+ required
+
+ - all hosts must implement the required protocol,
+
+ recommended
+
+ - all hosts are encouraged to implement the recommended
+ protocol,
+
+ elective
+
+ - hosts may implement or not the elective protocol,
+
+ experimental
+
+ - hosts should not implement the experimental protocol
+ unless they are participating in the experiment and have
+ coordinated their use of this protocol with the contact
+ person, and
+
+ none
+
+ - this is not a protocol.

+
+ Internet Protocol --------------------------------------------- (IP)
+
+ STATUS: Required
+
+ SPECIFICATION: RFC 791 (in IPTW)
+
+ COMMENTS:
+
+ This is the universal protocol of the Internet. This datagram
+ protocol provides the universal addressing of hosts in the
+ Internet.
+
+ A few minor problems have been noted in this document.
+
+ The most serious is a bit of confusion in the route options.
+ The route options have a pointer that indicates which octet of
+ the route is the next to be used. The confusion is between the
+ phrases "the pointer is relative to this option" and "the
+ smallest legal value for the pointer is 4". If you are
+ confused, forget about the relative part, the pointer begins
+ at 4.
+
+ Another important point is the alternate reassembly procedure
+ suggested in RFC 815.
+
+ Some changes are in the works for the security option.
+
+ Note that ICMP is defined to be an integral part of IP. You
+ have not completed an implementation of IP if it does not
+ include ICMP.

+ Internet Control Message Protocol --------------------------- (ICMP)
+
+ STATUS: Required
+
+ SPECIFICATION: RFC 792 (in IPTW)
+
+ COMMENTS:
+
+ The control messages and error reports that go with the
+ Internet Protocol.
+
+ A few minor errors in the document have been noted.
+ Suggestions have been made for additional types of redirect
+ message and additional destination unreachable messages.
+
+ A proposal for two additional ICMP message types is made in
+ RFC 950 "Internet Subnets", Address Mask Request (A1=17), and
+ Address Mask Reply (A2=18). The details of these ICMP types
+ are subject to change. Use of these ICMP types is
+ experimental.
+
+ Note that ICMP is defined to be an integral part of IP. You
+ have not completed an implementation of IP if it does not
+ include ICMP.

+HOST LEVEL
+
+ User Datagram Protocol --------------------------------------- (UDP)
+
+ STATUS: Recommended
+
+ SPECIFICATION: RFC 768 (in IPTW)
+
+ COMMENTS:
+
+ Provides a datagram service to applications. Adds port
+ addressing to the IP services.
+
+ The only change noted for the UDP specification is a minor
+ clarification that if in computing the checksum a padding octet
+ is used for the computation it is not transmitted or counted in
+ the length.

+
+ Transmission Control Protocol -------------------------------- (TCP)
+
+ STATUS: Recommended
+
+ SPECIFICATION: RFC 793 (in IPTW)
+
+ COMMENTS:
+
+ Provides reliable end-to-end data stream service.
+
+ Many comments and corrections have been received for the TCP
+ specification document. These are primarily document bugs
+ rather than protocol bugs.
+
+ Event Processing Section: There are many minor corrections and
+ clarifications needed in this section.
+
+ Push: There are still some phrases in the document that give a
+ "record mark" flavor to the push. These should be further
+ clarified. The push is not a record mark.
+
+ Urgent: Page 17 is wrong. The urgent pointer points to the
+ last octet of urgent data (not to the first octet of non-urgent
+ data).
+
+
+
+Reynolds & Postel [Page 6]
+
+
+
+Official ARPA-Internet Protocols RFC 961
+
+
+ Listening Servers: Several comments have been received on
+ difficulties with contacting listening servers. There should
+ be some discussion of implementation issues for servers, and
+ some notes on alternative models of system and process
+ organization for servers.
+
+ Maximum Segment Size: The maximum segment size option should
+ be generalized and clarified. It can be used to either
+ increase or decrease the maximum segment size from the default.
+ The TCP Maximum Segment Size is the IP Maximum Datagram Size
+ minus forty. The default IP Maximum Datagram Size is 576. The
+ default TCP Maximum Segment Size is 536. For further
+ discussion, see RFC 879.
+
+ Idle Connections: There have been questions about
+ automatically closing idle connections. Idle connections are
+ ok, and should not be closed. There are several cases where
+ idle connections arise, for example, in Telnet when a user is
+ thinking for a long time following a message from the server
+ computer before his next input. There is no TCP "probe"
+ mechanism, and none is needed.
+
+ Queued Receive Data on Closing: There are several points where
+ it is not clear from the description what to do about data
+ received by the TCP but not yet passed to the user,
+ particularly when the connection is being closed. In general,
+ the data is to be kept to give to the user if he does a RECV
+ call.
+
+ Out of Order Segments: The description says that segments that
+ arrive out of order, that is, are not exactly the next segment
+ to be processed, may be kept on hand. It should also point out
+ that there is a very large performance penalty for not doing
+ so.
+
+ User Time Out: This is the time out started on an open or send
+ call. If this user time out occurs the user should be
+ notified, but the connection should not be closed or the TCB
+ deleted. The user should explicitly ABORT the connection if he
+ wants to give up.

+ COMMENTS:
+
+ A very simple file moving protocol, no access control is
+ provided.
+
+ This is in use in several local networks.
+
+ Ambiguities in the interpretation of several of the transfer

+ Simple File Transfer Protocol ------------------------------- (SFTP)
+
+ STATUS: Experimental
+
+ SPECIFICATION: RFC 913
+
+ COMMENTS:
+
+ SFTP is a simple file transfer protocol. It fills the need of
+ people wanting a protocol that is more useful than TFTP but
+ easier to implement (and less powerful) than FTP. SFTP
+ supports user access control, file transfers, directory
+ listing, directory changing, file renaming and deleting.
+
+ SFTP can be implemented with any reliable 8-bit byte stream
+ oriented protocol, this document describes its TCP
+ specification. SFTP uses only one TCP connection; whereas TFTP
+ implements a connection over UDP, and FTP uses two TCP
+ connections (one using the TELNET protocol).
+
+ Please discuss any plans for implementation or use of this
+ protocol with the contact.

+ machines from hosts in a network environment. It is also
+ designed to accommodate a variety of target CPU types. It
+ provides a powerful set of debugging services, while at the
+ same time, it is structured so that a simple subset may be
+ implemented in applications like boot loading where efficiency
+ and space are at a premium.
