RFC0989 - Privacy enhancement for Internet electronic mail: Part I: Message encipherment and authentication procedures
This RFC suggests a proposed protocol for the Internet community and requests discussion and suggestions for improvements. This RFC is the outgrowth of a series of IAB Privacy Task Force meetings and of internal working papers distributed for those meetings. This RFC defines message encipherment and authentication procedures, as the initial phase of an effort to provide privacy enhancement services for electronic mail transfer in the Internet. It is intended that the procedures defined here be compatible with a wide range of key management approaches, including both conventional (symmetric) and public-key (asymmetric) approaches for encryption of data encrypting keys. Use of conventional cryptography for message text encryption and/or authentication is anticipated.
RFC0988 - Host extensions for IP multicasting
This memo 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 ARPA-Internet. The reader is directed to RFC-966 for a discussion of the motivation and rationale behind the multicasting extension specified here.
RFC0987 - Mapping between X.400 and RFC 822
The X.400 series protocols have been defined by CCITT to provide an Interpersonal Messaging Service (IPMS), making use of a store and forward Message Transfer Service. It is expected that this standard will be implemented very widely. This document describes a set of mappings which will enable interworking between systems operating the X.400 protocols and systems using RFC-822 mail protocol or protocols derived from RFC-822. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
RFC0986 - Guidelines for the use of Internet-IP addresses in the ISO Connectionless-Mode Network Protocol
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. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
RFC0985 - Requirements for Internet gateways - draft
This RFC summarizes the requirements for gateways to be used on networks supporting the DARPA Internet protocols. While it applies specifically to National Science Foundation research programs, the requirements are stated in a general context and are believed applicable throughout the Internet community. The purpose of this document is to present guidance for vendors offering products that might be used or adapted for use in an Internet application. It enumerates the protocols required and gives references to RFCs and other documents describing the current specification.
RFC0984 - PCMAIL: A distributed mail system for personal computers
This document is a preliminary discussion of the design of a personal-computer-based distributed mail system. Pcmail is a distributed mail system that provides mail service to an arbitrary number of users, each of which owns one or more personal computers (PCs). The system is divided into two halves. The first consists of a single entity called the "repository". The repository is a storage center for incoming mail. Mail for a Pcmail user can arrive externally from the Internet or internally from other repository users. The repository also maintains a stable copy of each user's mail state. The repository is therefore typically a computer with a large amount of disk storage. It is published for discussion and comment, and does not constitute a standard. As the proposal may change, implementation of this document is not advised. See RFC-993.
RFC0983 - ISO transport arrives on top of the TCP
This memo describes a proposed protocol standard for the ARPA 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 in the ARPA Internet, without disrupting existing facilities. This permits users to develop expertise with ISO and CCITT applications which previously were not available in the ARPA Internet. The intention is that hosts in the ARPA-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.
RFC0982 - Guidelines for the specification of the structure of the Domain Specific Part (DSP) of the ISO standard NSAP address
This RFC is a draft working document of the ANSI "Guidelines for the Specification of the Structure of the Domain Specific Part (DSP) of the ISO Standard NSAP Address". It provides guidance to private address administration authorities on preferred formats and semantics for the Domain Specific Part (DSP) of an NSAP address. This RFC specifies the way in which the DSP may be constructed so as to facilitate efficient address assignment. This RFC is for informational purposes only and its distribution is unlimited and does not specify a standard of the ARPA-Internet.
RFC0981 - Experimental multiple-path routing algorithm
This document introduces wiretap algorithms, a class of experimental, multiple routing algorithms that compute quasi-optimum routes for stations sharing a packet-radio broadcast channel. The primary route (a minimum-distance path), and additional paths ordered by distance, which serve as alternate routes should the primary route fail, are computed. This prototype is presented as an example of a class of routing algorithms and data-base management techniques that may find wider application in the Internet community. Discussions and suggestions for improvements are welcomed.
RFC0980 - Protocol document order information
This RFC indicates how to obtain various protocol documents used in the DARPA research community. Included is an overview of the new 1985 DDN Protocol Handbook and available sources for obtaining related documents (such as DOD, ISO, and CCITT).
RFC0979 - PSN End-to-End functional specification
This memo is an updated version of BBN Report 5775, "End-to-End Functional Specification and describes important changes to the functionality of the interface between a Host and the PSN, and should be carefully reviewed by anyone involved in supporting a host on either the ARPANET or MILNET". The new End-to-End protocol (EE) is being developed in order to correct a number of deficiencies in the old EE, to improve its performance and overall throughput, and to better equip the Packet Switch Node (PSN, also known as the IMP) to support its current and anticipated host population.
RFC0978 - Voice File Interchange Protocol (VFIP)
The purpose of the Voice File Interchange Protocol (VFIP) is to permit the interchange of various types of speech files between different systems in the ARPA-Internet community. Suggestions for improvement are encouraged.
RFC0977 - Network News Transfer Protocol
NNTP specifies a protocol for the distribution, inquiry, retrieval, and posting of news articles using a reliable stream-based transmission of news among the ARPA-Internet community. NNTP is designed so that news articles are stored in a central database allowing a subscriber to select only those items he wishes to read. Indexing, cross-referencing, and expiration of aged messages are also provided. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
RFC0976 - UUCP mail interchange format standard
This document defines the standard format for the transmission of mail messages between computers in the UUCP Project. It does not however, address the format for storage of messages on one machine, nor the lower level transport mechanisms used to get the date from one machine to the next. It represents a standard for conformance by hosts in the UUCP zone.
RFC0975 - Autonomous confederations
This RFC proposes enhancements to the Exterior Gateway Protocol (EGP) to support a simple, multiple-level routing capability while preserving the robustness features of the current EGP model. The enhancements generalize the concept of core system to include multiple communities of autonomous systems, called autonomous confederations. Discussion and suggestions for improvement are requested.
RFC0974 - Mail routing and the domain system
This RFC presents a description of how mail systems on the Internet are expected to route messages based on information from the domain system. This involves a discussion of how mailers interpret MX RRs, which are used for message routing.
RFC0973 - Domain system changes and observations
This RFC documents updates to Domain Name System specifications RFC-882 and RFC-883, suggests some operational guidelines, and discusses some experiences and problem areas in the present system.
RFC0972 - Password Generator Protocol
This RFC specifies a standard for the ARPA Internet community. The Password Generator Service (PWDGEN) provides a set of six randomly generated eight-character "words" with a reasonable level of pronounceability, using a multi-level algorithm. Hosts on the ARPA Internet that choose to implement a password generator service are expected to adopt and implement this standard.
RFC0971 - Survey of data representation standards
This RFC is a comparison of several data representation standards that are currently in use. The standards discussed are the CCITT X.409 recommendation, the NBS Computer Based Message System (CBMS) standard, DARPA Multimedia Mail system, the Courier remote procedure call protocol, and the SUN Remote Procedure Call package. No proposals in this document are intended as standards for the ARPA-Internet at this time. Rather, it is hoped that a general consensus will emerge as to the appropriate approach to a data representation standard, leading eventually to the adoption of an ARPA-Internet standard.
RFC0970 - On Packet Switches With Infinite Storage
The purpose of this RFC is to focus discussion on a particular problem in the ARPA-Internet and possible methods of solution. Most prior work on congestion in datagram systems focuses on buffer management. In this memo the case of a packet switch with infinite storage is considered. Such a packet switch can never run out of buffers. It can, however, still become congested. The meaning of congestion in an infinite-storage system is explored. An unexpected result is found that shows a datagram network with infinite storage, first-in-first-out queuing, at least two packet switches, and a finite packet lifetime will, under overload, drop all packets. By attacking the problem of congestion for the infinite-storage case, new solutions applicable to switches with finite storage may be found. No proposed solutions this document are intended as standards for the ARPA-Internet at this time.
RFC0969 - NETBLT: A bulk data transfer protocol
This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements. This is a preliminary discussion of the Network Block Transfer (NETBLT) protocol. NETBLT is 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 structured to provide maximum throughput over a wide variety of networks. This description is published for discussion and comment, and does not constitute a standard. As the proposal may change, implementation of this document is not advised. See RFC-998.
RFC0968 - Twas the night before start-up
This memo discusses problems that arise and debugging techniques used in bringing a new network into operation.
RFC0967 - All victims together
This RFC proposes a new set of RFCs on how the networking code is integrated with various operating systems. It appears that this topic has not received enough exposure in the literature. Comments and suggestions are encouraged.
RFC0966 - Host groups: A multicast extension to the Internet Protocol
This RFC defines a model of service for Internet multicasting and proposes an extension to the Internet Protocol (IP) to support such a multicast service. Discussion and suggestions for improvements are requested. See RFC-988.
RFC0965 - Format for a graphical communication protocol
This RFC describes the requirements for a graphical format on which to base a graphical on-line communication protocol, and proposes an Interactive Graphical Communication Format using the GKSM session metafile. We hope this contribution will encourage the discussion of multimedia data exchange and the proposal of solutions.
RFC0964 - Some problems with the specification of the Military Standard Transmission Control Protocol
The purpose of this RFC is to provide helpful information on the Military Standard Transmission Control Protocol (MIL-STD-1778) so that one can obtain a reliable implementation of this protocol standard. This note points out three errors with this specification. This note also proposes solutions to these problems.
RFC0963 - Some problems with the specification of the Military Standard Internet Protocol
The purpose of this RFC is to provide helpful information on the Military Standard Internet Protocol (MIL-STD-1777) so that one can obtain a reliable implementation of this protocol. This paper points out several problems in this specification. This note also proposes solutions to these problems.
RFC0962 - TCP-4 prime
This memo is in response to Bob Braden's call for a transaction oriented protocol (RFC-955), and continues the discussion of a possible transaction oriented transport protocol. This memo does not propose a standard.
RFC0961 - Official ARPA-Internet protocols
This memo identifies the documents specifying the official protocols used in the Internet, and comments on any revisions or changes planned. This edition of the Official Protocols updates and obsoletes RFC-944. This memo is an official status report on the protocols used in the ARPA-Internet community. See RFC-991.
RFC0960 - Assigned numbers
This memo documents the currently assigned values from several series of numbers used in network protocol implementations. This edition of Assigned Numbers updates and obsoletes RFC-943. This memo is an official status report on the numbers used in protocols in the ARPA-Internet community. See RFC-990 and 997.
RFC0959 - File Transfer Protocol
This memo is the official specification of the File Transfer Protocol (FTP) for the DARPA Internet community. The primary intent is to clarify and correct the documentation of the FTP specification, not to change the protocol. The following new optional commands are included in this edition of the specification: Change to Parent Directory (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.
RFC0958 - Network Time Protocol (NTP)
This document describes the Network Time Protocol (NTP), a protocol for synchronizing a set of network clocks using a set of distributed clients and servers. NTP is built on the User Datagram Protocol (UDP), which provides a connectionless transport mechanism. It is evolved from the Time Protocol and the ICMP Timestamp message and is a suitable replacement for both. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
RFC0957 - Experiments in network clock synchronization
This RFC discusses some experiments in clock synchronization in the ARPA-Internet community, and requests discussion and suggestions for improvements. One of the services frequently neglected in computer network design is a high-quality, time-of-day clock capable of generating accurate timestamps with small errors compared to one-way network delays. Such a service would be useful for tracing the progress of complex transactions, synchronizing cached data bases, monitoring network performance and isolating problems. In this memo one such clock service design will be described and its performance assessed. This design has been incorporated as an integral part of the network routing and control protocols of the Distributed Computer Network (DCnet) architecture.
RFC0956 - Algorithms for synchronizing network clocks
This RFC discussed clock synchronization algorithms for the ARPA-Internet community, and requests discussion and suggestions for improvements. The recent interest within the Internet community in determining accurate time from a set of mutually suspicious network clocks has been prompted by several occasions in which errors were found in usually reliable, accurate clock servers after thunderstorms which disrupted their power supply. To these sources of error should be added those due to malfunctioning hardware, defective software and operator mistakes, as well as random errors in the mechanism used to set and synchronize clocks. This report suggests a stochastic model and algorithms for computing a good estimator from time-offset samples measured between clocks connected via network links. Included in this report are descriptions of certain experiments which give an indication of the effectiveness of the algorithms.
RFC0955 - Towards a transport service for transaction processing applications
The DoD Internet protocol suite includes two alternative transport service protocols, TCP and UDP, which provide virtual circuit and datagram service, respectively. These two protocols represent points in the space of possible transport service attributes which are quite "far apart". We want to examine an important class of applications, those which perform what is often called "transaction processing". We will see that the communication needs for these applications fall into the gap "between" TCP and UDP -- neither protocol is very appropriate. This RFC is concerned with the possible design of one or more new protocols for the ARPA-Internet, to support kinds of applications which are not well supported at present. The RFC is intended to spur discussion in the Internet research community towards the development of new protocols and/or concepts, in order to meet these unmet application requirements. It does not represent a standard, nor even a concrete protocol proposal.
RFC0954 - NICNAME/WHOIS
This RFC is the official specification of the NICNAME/WHOIS protocol. This memo describes the protocol and the service. This is an update of RFC-812.
RFC0953 - Hostname Server
This RFC is the official specification of the Hostname Server Protocol. This edition of the specification includes minor revisions to RFC-811 which brings it up to date.
RFC0952 - DoD Internet host table specification
This RFC is the official specification of the format of the Internet Host Table. This edition of the specification includes minor revisions to RFC-810 which brings it up to date.
RFC0951 - Bootstrap Protocol
This RFC describes an IP/UDP bootstrap protocol (BOOTP) which allows a diskless client machine to discover its own IP address, the address of a server host, and the name of a file to be loaded into memory and executed. The bootstrap operation can be thought of as consisting of TWO PHASES. This RFC describes the first phase, which could be labeled `address determination and bootfile selection'. After this address and filename information is obtained, control passes to the second phase of the bootstrap where a file transfer occurs. The file transfer will typically use the TFTP protocol, since it is intended that both phases reside in PROM on the client. However BOOTP could also work with other protocols such as SFTP or FTP. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
RFC0950 - Internet Standard Subnetting Procedure
This memo discusses the utility of "subnets" of Internet networks, which are logically visible sub-sections of a single Internet network. For administrative or technical reasons, many organizations have chosen to divide one Internet network into several subnets, instead of acquiring a set of Internet network numbers. This memo specifies procedures for the use of subnets. These procedures are for hosts (e.g., workstations). The procedures used in and between subnet gateways are not fully described. Important motivation and background information for a subnetting standard is provided in RFC-940. This RFC specifies a protocol for the ARPA-Internet community. If subnetting is implemented it is strongly recommended that these procedures be followed.
RFC0949 - FTP unique-named store command
There are various contexts in which it would be desirable to have an FTP command that had the effect of the present STOR but rather than requiring the sender to specify a file name istead caused the resultant file to have a unique name relative to the current directory. This RFC proposes an extension to the File Transfer Protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements. See RFC-959.
RFC0948 - Two methods for the transmission of IP datagrams over IEEE 802.3 networks
This RFC describes two methods of encapsulating Internet Protocol (IP) datagrams on an IEEE 802.3 network. This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements.
