Robert Hinden of BBNCC chaired, and Jon Postel of ISI hosted the meeting. Approximately 35 gateway designers and implementors attended. These notes are based on the recollections of Jon Postel and Mike Muuss. Under each topic area are Jon Postel's brief notes, and additional details from Mike Muuss. This memo is a report on a meeting. No conclusions, decisions, or policy statements are documented in this note. 897 Postel Feb 84 Domain Name System Implementation Schedule This memo is a policy statement on the implementation of the Domain Style Naming System in the Internet. This memo is a partial update of RFC 881. The intent of this memo is to detail the schedule for the implementation for the Domain Style Naming System. The names of hosts will be changed to domain style names. Hosts will begin to use domain style names on 14-Mar-84, and the use of old style names will be completely phased out before 2-May-84. This applies to both the ARPA research hosts and the DDN operational hosts. This is an official policy statement of the ICCB and the DARPA. Postel & Westine [page 1] RFC 899 May 1984 896 Nagle Jan 84 Congestion Control in IP/TCP Internetworks This memo discusses some aspects of congestion control in IP/TCP Internetworks. It is intended to stimulate thought and further discussion of this topic. While some specific suggestions are made for improved congestion control implementation, this memo does not specify any standards. 895 Postel Apr 84 A Standard for the Transmission of IP Datagrams over Experimental Ethernet Networks This RFC specifies a standard method of encapsulating Internet Protocol (IP) datagrams on an Experimental Ethernet. This RFC specifies a standard protocol for the ARPA Internet community. 894 Hornig Apr 84 A Standard for the Transmission of IP Datagrams over Ethernet Networks This RFC specifies a standard method of encapsulating Internet Protocol (IP) datagrams on an Ethernet.

This document is for information only. This is NOT an official protocol for the ARPA Internet community. 892 ISO Dec 83 ISO Transport Protocol Specification This is a draft version of the transport protocol being standardized by the ISO. This version also appeared in the ACM SIGCOMM Computer Communication Review (V.12, N.3-4) July-October 1982. This version is now out of date. 891 Mills Dec 83 DCN Local-Network Protocols This RFC provides a description of the DCN protocols for maintaining connectivity, routing, and clock information in a local network. These procedures may be of interest to the designers and implementers of other local networks. Postel & Westine [page 2] RFC 899 May 1984 890 Postel Feb 84 Exterior Gateway Protocol Implementation Schedule This memo is a policy statement on the implementation of the Exterior Gateway Protocol in the Internet. This is an official policy statement of ICCB and DARPA. After 1-Aug-84 there shall be no dumb gateways in the Internet. Every gateway must be a member of some autonomous system. Some gateway of each autonomous system must exchange routing information with some gateway of the core autonomous system using the Exterior Gateway Protocol. 889 Mills Dec 83 Internet Delay Experiments This memo reports on some measurements of round-trip times in the Internet and suggests some possible improvements to the TCP retransmission timeout calculation. This memo is both a status report on the Internet and advice to TCP implementers. 888 Seamonson Jan 84 "Stub" Exterior Gateway Protocol This RFC describes the Exterior Gateway Protocol used to connect Stub Gateways to an Autonomous System of core Gateways. This document specifies the working protocol, and defines an ARPA official protocol. All implementers of Gateways should carefully review this document. 887 Accetta Dec 83 Resource Location Protocol This RFC specifies a draft standard for the ARPA Internet community. It describes a resource location protocol for use in the ARPA Internet. It is most useful on networks employing technologies which support some method of broadcast addressing, however it may also be used on other types of networks. For maximum benefit, all hosts which provide significant resources or services to other hosts on the Internet should implement this protocol. Hosts failing to implement the Resource Location Protocol risk being ignored by other hosts which are attempting to locate resources on the Internet. 886 Rose Dec 83 Proposed Standard for Message Header Munging This RFC specifies a draft standard for the ARPA Internet community. It describes the rules to be used when transforming mail from the conventions of one message system to those of another message system.

Postel & Westine [page 8] RFC 899 May 1984 854 Postel May 83 Telnet Protocol Specifications This is the specification of the Telnet protocol used for remote terminal access in the ARPA Internet. The purpose of the TELNET Protocol is to provide a fairly general, bi-directional, eight-bit byte oriented communications facility. Its primary goal is to allow a standard method of interfacing terminal devices and terminal-oriented processes to each other. It is envisioned that the protocol may also be used for terminal-terminal communication ("linking") and process-process communication (distributed computation). This RFC specifies a standard for the ARPA Internet community. Hosts on the ARPA Internet are expected to adopt and implement this standard. Obsoletes NIC 18639. 853 Not issued yet. 852 Malis Apr 83 The ARPANET Short Blocking Feature This RFC specifies the ARPANET Short Blocking Feature, which will allow ARPANET hosts to optionally shorten the IMP's host blocking timer. This Feature is a replacement of the ARPANET non-blocking host interface, which was never implemented, and will be available to hosts using either the 1822 or 1822L Host Access Protocol. This RFC is also being presented as a solicitation of comments on the Short Blocking Feature, especially from host network software implementers and maintainers. 851 Malis Apr 83 The ARPANET 1822L Host Access Protocol This RFC specifies the ARPANET 1822L Host Access Protocol, which is a successor to the existing 1822 Host Access Protocol. 1822L allows ARPANET hosts to use logical names as well as 1822's physical port locations to address each other. This RFC is also being presented as a solicitation of comments on 1822L, especially from host network software implementers and maintainers. Obsoletes RFC 802. 850 Horton Jun 83 Standard for Interchange of USENET Messages This memo is distributed as an RFC only to make this information easily accessible to researchers in the ARPA community. It does not specify an Internet standard. This RFC defines the standard format for interchange of Network News articles among USENET sites. It describes the format for articles themselves, and gives partial standards for transmission of news. The news transmission is not entirely standardized in order to give a good deal of flexibility to the individual hosts to choose transmission hardware and software, whether to batch news and so on. Postel & Westine [page 9] RFC 899 May 1984 849 Crispin May 83 Suggestions for Improved Host Table Distribution This RFC actually is a request for comments. The issue dealt with is that of a naming registry update procedure, both as exists currently and what could exist in the future. None of the proposed solutions are intended as standards at this time; rather it is hoped that a general consensus will emerge as the appropriate solution, leaving eventually to the adoption of standards. 848 Smallberg Mar 83 Who provides the "Little" TCP Services? This RFC lists those hosts which provide any of these "little" TCP services: The list of hosts were taken from the NIC hostname table of 24-Feb-83.

This document is a DRAFT for that standard. Your comments are strongly encouraged. 826 Plummer Nov 82 An Ethernet Address Resolution Protocol The purpose of this RFC is to present a method of Converting Protocol Addresses (e.g., IP addresses) to Local Network Addresses (e.g., Ethernet addresses). This is an issue of general concern in the ARPA Internet Community at this time. The method proposed here is presented for your consideration and comment. This is not the specification of an Internet Standard. Postel & Westine [page 13] RFC 899 May 1984 825 Postel Nov 82 Request for Comments on Requests for Comments This RFC is intended to clarify the status of RFCs and to provide some guidance for the authors of RFCs in the future. It is in a sense a specification for RFCs. 824 MacGregor Aug 82 The Cronus Virtual Local Network The purpose of this note is to describe the CRONUS Virtual Local Network, especially the addressing related features.

This note is intended to stimulate discussion. This is not a specification of an Internet Standard. 823 Hinden Sep 82 The DARPA Internet Gateway This RFC is a status report on the Internet Gateway developed by BBN. It describes the Internet Gateway as of September 1982. This memo presents detailed descriptions of message formats and gateway procedures, however, this is not an implementation specification, and such details are subject to change. 822 Crocker Aug 82 Standard for the Format of ARPA Internet Text Messages This document revises the specifications in RFC 733, in order to serve the needs of the larger and more complex ARPA Internet. Some of RFC 733's features failed to gain adequate acceptance. In order to simplify the standard and the software that follows it, these features have been removed. A different addressing scheme is used, to handle the case of internetwork mail; and the concept of re-transmission has been introduced. Obsoletes RFC 733, NIC 41952. 821 Postel Aug 82 Simple Mail Transfer Protocol The objective of Simple Mail Transfer Protocol (SMTP) is to transfer mail reliably and efficiently. SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel. Obsoletes RFC 788, 780, and 772. 820 Postel Jan 82 Assigned Numbers This RFC is an old version, see RFC 870. Postel & Westine [page 14] RFC 899 May 1984 819 Zaw-Sing Su Aug 82 The Domain Naming Convention for Internet User Applications This RFC is an attempt to clarify the generalization of the Domain Naming Convention, the Internet Naming Convention, and to explore the implications of its adoption for Internet name service and user applications. 818 Postel Nov 82 The Remote User Telnet Service This RFC is the specification of an application protocol. Any host that implements this application level service must follow this protocol. 817 Clark Jul 82 Modularity and Efficiency in Protocol Implementation This RFC will discuss some of the commonly encountered reasons why protocol implementations seem to run slowly. 816 Clark Jul 82 Fault Isolation and Recovery This RFC describes the portion of fault isolation and recovery which is the responsibility of the host. 815 Clark Jul 82 IP Datagram Reassembly Algorithms This RFC describes an alternate approach of dealing with reassembly which reduces the bookkeeping problem to a minimum, and requires only one buffer for storage equal in size to the final datagram being reassembled, which can reassemble a datagram from any number of fragments arriving in any order with any possible pattern of overlap and duplication, and which is appropriate for almost any sort of operating system. 814 Clark Jul 82 Name, Addresses, Ports, and Routes This RFC gives suggestions and guidance for the design of the tables and algorithms necessary to keep track of these various sorts of identifiers inside a host implementation of TCP/IP. 813 Clark Jul 82 Window and Acknowledgement Strategy in TCP This RFC describes implementation strategies to deal with two mechanisms in TCP, the window and the acknowledgement. It also presents a particular set of algorithms which have received testing in the field, and which appear to work properly with each other. With more experience, these algorithms may become part of the formal specification, until such time their use is recommended. Postel & Westine [page 15] RFC 899 May 1984 812 Harrenstien Mar 82 NICNAME/WHOIS This RFC gives a description of what the NICNAME/WHOIS Server is and how to access it. This server together with the corresponding Identification Data Base provides online directory look-up equivalent to the ARPANET Directory. 811 Harrenstien Mar 82 Hostnames Server This RFC gives a description of what the Hostnames Server is and how to access it. The function of this particular server is to deliver machine-readable name/address information describing networks, gateways, hosts, and eventually domains, within the internet environment. 810 Feinler Mar 82 DoD Internet Host Table Specification This RFC specifies a new host table format applicable to both ARPANET and Internet needs. In addition to host name to host address translation and selected protocol information, we have also included network and gateway name to address correspondence, and host operating system information. This RFC obsoletes the host table described in RFC 608. 809 Chang Feb 82 UCL Facsimile System This RFC describes the features of the computerised facsimile system developed in the Department of Computer Science at UCL.

Finally, the implementation of the system are described, while detailed description are given as appendices. 808 Postel Mar 82 Summary of Computer Mail Services Meeting Held at BBN on 10 January 1979 This RFC is a very belated attempt to document a meeting that was held three years earlier to discuss the state of computer mail in the ARPA community and to reach some conclusions to guide the further development of computer mail systems such that a coherent total mail service would continue to be provided. 807 Postel Feb 82 Multimedia Mail Meeting Notes This RFC consists of notes from a meeting held at USC Information Sciences Institute on the 12th of January to discuss common interests in multimedia computer mail issues and to agree on some specific initial experiments. Postel & Westine [page 16] RFC 899 May 1984 806 NBS Sep 81 Specification for Message Format for Computer Based Message Systems This RFC deals with Computer Based Message systems which provides a basis for interaction between different CBMS by defining the format of messages passed between them. This RFC is replaced by RFC 841. 805 Postel Feb 82 Computer Mail Meeting Notes This RFC consists of notes from a meeting that was held at USC Information Sciences Institute on 11 January 1982, to discuss addressing issues in computer mail. The major conclusion reached at the meeting is to extend the "username@hostname" mailbox format to "username@host.domain", where the domain itself can be further strutured. 804 CCITT Jan 82 CCITT Draft Recommendation T.4 This is the CCITT standard for group 3 facsimile encoding. This is useful for data compression of bit map data. 803 Agarwal Nov 81 Dacom 450/500 Facsimile Data Transcoding The first part of this RFC describes in detail the Dacom 450 data compression algorithms and is an update and correction to an earlier memorandum. The second part of this RFC describes briefly the Dacom 500 data compression algorithm as used by the INTELPOST electronic-mail network under development by the US Postal Service and several foreign administrators. 802 Malis Nov 81 The ARPANET 1822L Host Access Protocol This document proposed two major changes to the current ARPANET host access protocol. The first change will allow hosts to use logical addressing (i.e., host addresses that are independent of their physical location on the ARPANET) to communicate with each other, and the second will allow a host to shorten the amount of time that it may be blocked by its IMP after it presents a message to the network (currently, the IMP can block further input from a host for up to 15 seconds). See RFCs 852 and 851. 801 Postel Nov 81 NCP/TCP Transition Plan This RFC discusses the conversion of hosts from NCP to TCP. And making available the principle services: Telnet, File Transfer, and Mail. These protocols allow all hosts in the ARPA community to share a common interprocess communication environment.
