OFFICIAL INTERNET PROTOCOLS
STATUS OF THIS MEMO
This memo is an official status report on the protocols used in the
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 specified in the
"DDN Protocol Handbook" (DPH), dated December 1985 (this is a three
volume set with a total thickness of about 5 inches).
Older collections that include many of these specifications are the
"Internet Protocol Transition Workbook" (IPTW), dated March 1982; the
"Internet Mail Protocols", dated November 1982; and the "Internet
Telnet Protocols and Options", dated June 1983. There is also a
volume of protocol related information called the "Internet Protocol
Implementers Guide" (IPIG) dated August 1982. An even older
collection is the "ARPANET Protocol Handbook" (APH) dated
January 1978. Nearly all the relevant material from these
collections has been reproduced in the current DPH.
The following material 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,
experimental, or none.
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.

RFC 1011 - Official Internet Protocols May 1987 OVERVIEW Catenet Model ------------------------------------------------------ STATUS: None SPECIFICATION: IEN 48 (in DPH) COMMENTS: Gives an overview of the organization and principles of the Internet. Could be revised and expanded. OTHER REFERENCES: Leiner, B., Cole R., Postel, J., and D. Mills, "The DARPA Protocol Suite", IEEE INFOCOM 85, Washington, D.C., March 1985.

RFC 1011 - Official Internet Protocols May 1987 NETWORK LEVEL Internet Protocol --------------------------------------------- (IP) STATUS: Required SPECIFICATION: RFC 791 (in DPH) 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. The MIL-STD description of source routing is wrong in some of the details. 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. The subnet procedures defined in RFC 950 are now considered an essential part of the IP architecture and must be implemented by all hosts and gateways.

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. Two additional ICMP message types are defined in RFC 950 "Internet Subnets", Address Mask Request (A1=17), and Address Mask Reply (A2=18). 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. OTHER REFERENCES: RFC 950 DEPENDENCIES: Internet Protocol CONTACT: Postel@ISI.EDU Reynolds & Postel [Page 5]
RFC 1011 - Official Internet Protocols May 1987 Internet Group Multicast Protocol --------------------------- (IGMP) STATUS: Recommended SPECIFICATION: RFC 988 COMMENTS: This protocol specifies the extensions required of a host implementation of the Internet Protocol (IP) to support internetwork multicasting. This specification supersedes that given in RFC 966, and constitutes a proposed protocol standard for IP multicasting in the Internet. Reference RFC 966 for a discussion of the motivation and rationale behind the multicasting extension specified here.

RFC 1011 - Official Internet Protocols May 1987 HOST LEVEL User Datagram Protocol --------------------------------------- (UDP) STATUS: Recommended SPECIFICATION: RFC 768 (in DPH) 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. OTHER REFERENCES: DEPENDENCIES: Internet Protocol CONTACT: Postel@ISI.EDU Transmission Control Protocol -------------------------------- (TCP) STATUS: Recommended SPECIFICATION: RFC 793 (in DPH) 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. Reynolds & Postel [Page 7]
RFC 1011 - Official Internet Protocols May 1987 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). 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.

DEPENDENCIES: Internet Protocol CONTACT: Postel@ISI.EDU Bulk Data Transfer Protocol ------------------------------- (NETBLT) STATUS: Experimental SPECIFICATION: RFC 998 COMMENTS: This is a revised RFC on the discussion of the Network Block Transfer (NETBLT) protocol. NETBLT (NETwork BLock Transfer) is a transport level protocol intended for the rapid transfer of a large quantity of data between computers. It provides a transfer that is reliable and flow controlled, and is designed to provide maximum throughput over a wide variety of networks. Although NETBLT currently Reynolds & Postel [Page 9]
RFC 1011 - Official Internet Protocols May 1987 runs on top of the Internet Protocol (IP), it should be able to operate on top of any datagram protocol similar in function to IP. This document is published for discussion and comment, and does not constitute a standard. The proposal may change and certain parts of the protocol have not yet been specified; implementation of this document is therefore not advised.

OTHER REFERENCES: DEPENDENCIES: Telnet CONTACT: Postel@ISI.EDU SUPDUP Protocol ------------------------------------------- (SUPDUP) STATUS: Elective SPECIFICATION: RFC 734 (in DPH) COMMENTS: A special Telnet like protocol for display terminals. OTHER REFERENCES: DEPENDENCIES: Transmission Control Protocol CONTACT: Crispin@SU-SCORE.STANFORD.EDU File Transfer Protocol --------------------------------------- (FTP) STATUS: Recommended SPECIFICATION: RFC 959 (in DPH) COMMENTS: The protocol for moving files between Internet hosts. Provides for access control and negotiation of file parameters. The following new optional commands are included in this edition of the specification: Change to Parent Directory Reynolds & Postel [Page 17]
RFC 1011 - Official Internet Protocols May 1987 (CDUP), Structure Mount (SMNT), Store Unique (STOU), Remove Directory (RMD), Make Directory (MKD), Print Directory (PWD), and System (SYST). Note that this specification is compatible with the previous edition (RFC 765). A discrepancy has been found in the specification in the examples of Appendix II. On page 63, a response code of 200 is shown as the response to a CWD command. Under the list of Command-Reply Sequences cited on page 50, CWD is shown to only accept a 250 response code. Therefore, if one would interpret a CWD command as being excluded from the File System functional category, one may assume that the response code of 200 is correct, since CDUP as a special case of CWD does use 200.

This is in use in several local networks. Ambiguities in the interpretation of several of the transfer modes should be clarified, and additional transfer modes could be defined. Additional error codes could be defined to more clearly identify problems. Note: The DPH contains IEN-133, which is an obsolete version of this protocol. OTHER REFERENCES: Reynolds & Postel [Page 18]
RFC 1011 - Official Internet Protocols May 1987 DEPENDENCIES: User Datagram Protocol CONTACT: Postel@ISI.EDU Simple File Transfer Protocol ------------------------------- (SFTP) STATUS: Experimental SPECIFICATION: RFC 913 (in DPH) 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. OTHER REFERENCES: DEPENDENCIES: Transmission Control Protocol CONTACT: MKL@SRI-NIC.ARPA Simple Mail Transfer Protocol ------------------------------- (SMTP) STATUS: Recommended SPECIFICATION: RFC 821 (in DPH) COMMENTS: The procedure for transmitting computer mail between hosts. This has been revised since the IPTW, it is in the "Internet Mail Protocols" volume of November 1982. RFC 788 (in IPTW) is obsolete. Reynolds & Postel [Page 19]
RFC 1011 - Official Internet Protocols May 1987 There have been many misunderstandings and errors in the early implementations. Some documentation of these problems can be found in the file [C.ISI.EDU]<SMTP>MAIL.ERRORS. Some minor differences between RFC 821 and RFC 822 should be resolved. OTHER REFERENCES: RFC 822 - Mail Header Format Standards This has been revised since the IPTW, it is in the "Internet Mail Protocols" volume of November 1982. RFC 733 (in IPTW) is obsolete. Further revision of RFC 822 is needed to correct some minor errors in the details of the specification. Note: RFC 822 is not included in the DPH (an accident, it should have been). MIL-STD-1781 (in DPH) - Simple Mail Transfer Protocol (SMTP) DEPENDENCIES: Transmission Control Protocol CONTACT: Postel@ISI.EDU Network News Transfer Protocol ------------------------------ (NNTP) STATUS: Experimental SPECIFICATION: RFC 977 COMMENTS: NNTP specifies a protocol for the distribution, inquiry, retrieval, and posting of news articles using a reliable stream-based transmission of news among the Internet community.

RFC 1011 - Official Internet Protocols May 1987 Internet Protocol on Experimental Ethernet Networks -------- (IP-EE) STATUS: Recommended SPECIFICATION: RFC 895 (in DPH) COMMENTS: OTHER REFERENCES: CONTACT: Postel@ISI.EDU Internet Protocol on IEEE 802 ---------------------------- (IP-IEEE) STATUS: Recommended SPECIFICATION: see comments COMMENTS: At an ad hoc special session on "IEEE 802 Networks and ARP" held during the TCP Vendors Workshop (August 1986), an approach to a consistent way to sent DOD-IP datagrams and other IP related protocols on 802 networks was developed. Due to some evolution of the IEEE 802.2 standards and the need to provide for a standard way to do additional DOD-IP related protocols (such as Address Resolution Protocol (ARP)) on IEEE 802 networks, the following new policy is established, which will replace the current policy (see RFC-990 section on IEEE 802 Numbers of Interest, and RFC-948). The policy is for DDN and Internet community to use IEEE 802.2 encapsulation on 802.3, 802.4, and 802.5 networks by using the SNAP with an organization code indicating that the following 16 bits specify the Ethertype code (where IP = 2048 (0800 hex), see RFC-1010 section on Ethernet Numbers of Interest). Header ...--------+--------+--------+ MAC Header| Length | 802.{3/4/5} MAC ...--------+--------+--------+ +--------+--------+--------+ | Dsap=K1| Ssap=K1| control| 802.2 SAP +--------+--------+--------+ Reynolds & Postel [Page 42]
RFC 1011 - Official Internet Protocols May 1987 +--------+--------+---------+--------+--------+ |protocol id or org code =K2| Ether Type | 802.2 SNAP +--------+--------+---------+--------+--------+ The total length of the SAP Header and the SNAP header is 8-octets, making the 802.2 protocol overhead come out on a nice boundary. K1 is 170. The IEEE like to talk about things in bit transmission order and specifies this value as 01010101. In big-endian order, as used in Internet specifications, this becomes 10101010 binary, or AA hex, or 170 decimal. K2 is 0 (zero). Note: The method described in RFC 948 (in DPH) is no longer to be used.

RFC 1011 - Official Internet Protocols May 1987 ISO and CCITT PROTOCOLS The International Standards Organization (ISO) and the International Telegraph and Telephone Consultative Committee (CCITT) are defining a set of protocols that may be of interest to the Internet community. Some of these have been published as RFCs for information purposes. This section lists these protocols. End System to Intermediate System Routing Exchange Protocol -------- STATUS: SPECIFICATION: RFC 995 COMMENTS: This protocol is one of a set of International Standards produced to facilitate the interconnection of open systems. The set of standards covers the services and protocols required to achieve such interconnection. This protocol is positioned with respect to other related standards by the layers defined in the Reference Model for Open Systems Interconnection (ISO 7498) and by the structure defined in the Internal Organization of the Network Layer (DIS 8648). In particular, it is a protocol of the Network Layer. This protocol permits End Systems and Intermediate Systems to exchange configuration and routing information to facilitate the operation of the routing and relaying functions of the Network Layer.

RFC 1011 - Official Internet Protocols May 1987 Protocol Standard is positioned with respect to other related standards by the layers defined in the Reference Model for Open Systems Interconnection (ISO 7498). In particular, it is a protocol of the Network Layer. This Protocol may be used between network-entities in end systems or in Network Layer relay systems (or both). It provides the Connectionless-mode Network Service as defined in Addendum 1 to the Network Service Definition Covering Connectionless-mode Transmission (ISO 8348/AD1). OTHER REFERENCES: RFC 926 DEPENDENCIES: CONTACT: ANSI Internet-IP Addressing in ISO-IP ----------------------------------- STATUS: SPECIFICATION: RFC 986 COMMENTS: This RFC suggests a method to allow the existing IP addressing, including the IP protocol field, to be used for the ISO Connectionless Network Protocol (CLNP). This is a draft solution to one of the problems inherent in the use of "ISO-grams" in the DoD Internet. Related issues will be discussed in subsequent RFCs.

RFC 1011 - Official Internet Protocols May 1987 ISO Transport Services on Top of the TCP --------------------------- STATUS: SPECIFICATION: RFC 1006 COMMENTS: This memo describes a proposed protocol standard for the Internet community. The CCITT and the ISO have defined various session, presentation, and application recommendations which have been adopted by the international community and numerous vendors. To the largest extent possible, it is desirable to offer these higher level services directly to the Internet, without disrupting existing facilities. This permits users to develop expertise with ISO and CCITT applications which previously were not available in the Internet. The intention is that hosts within the Internet that choose to implement ISO TSAP services on top of the TCP be expected to adopt and implement this standard. Suggestions for improvement are encouraged. Please discuss any plans for implementation or use of this protocol with the contact.
