RFC 1508 Generic Security Service Application Program Interface
 
Authors:J. Linn.
Date:September 1993
Formats:txt pdf
Obsoleted by:RFC 2078
Status:PROPOSED STANDARD
This Generic Security Service Application Program Interface (GSS-API) definition provides security services to callers in a generic fashion, supportable with a range of underlying mechanisms and technologies and hence allowing source-level portability of applications to different environments. This specification definesGSS-API services and primitives at a level independent of underlying mechanism and programming language environment, and is to be complemented by other, related specifications: documents defining specific parameter bindings for particular language environments documents defining token formats, protocols, and procedures to be implemented in order to realize GSS-API services atop particular security mechanisms
 
RFC 1509 Generic Security Service API : C-bindings
 
Authors:J. Wray.
Date:September 1993
Formats:txt pdf
Obsoleted by:RFC 2744
Status:PROPOSED STANDARD
This document specifies C language bindings for the Generic SecurityService Application Program Interface (GSS-API), which is described at a language-independent conceptual level in other documents.

The Generic Security Service Application Programming Interface (GSS-API) provides security services to its callers, and is intended for implementation atop alternative underlying cryptographic mechanisms.Typically, GSS-API callers will be application protocols into which security enhancements are integrated through invocation of services provided by the GSS-API. The GSS-API allows a caller application to authenticate a principal identity associated with a peer application, to delegate rights to a peer, and to apply security services such as confidentiality and integrity on a per-message basis.

Formats:txt pdf
Updates:RFC 1285
Status:HISTORIC
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets.In particular, it defines objects for managing devices which implement the FDDI based on the ANSI FDDI SMT 7.3 draft standard [8], which has been forwarded for publication by the X3T9.5 committee.
 
RFC 1513 Token Ring Extensions to the Remote Network Monitoring MIB
 
Authors:S. Waldbusser.
Date:September 1993
Formats:txt pdf
Updates:RFC 1271
Status:HISTORIC
This memo defines extensions to the Remote Network Monitoring MIB for managing 802.5 Token Ring networks.

The Remote Network Monitoring MIB, RFC 1271, defines a framework for remote monitoring functions implemented on a network probe. That MIB defines objects broken down into nine functional groups. Some of those functional groups, the statistics and the history groups, have a view of the data-link layer that is specific to the media type and require specific objects to be defined for each media type. RFC 1271 defined those specific objects necessary for Ethernet. This companion memo defines those specific objects necessary for TokenRing LANs.

In addition, this memo defines some additional monitoring functions specifically for Token Ring. These are defined in the Ring StationGroup, the Ring Station Order Group, the Ring Station ConfigurationGroup, and the Source Routing Statistics Group.

 
RFC 1514 Host Resources MIB
 
Authors:P. Grillo, S. Waldbusser.
Date:September 1993
Formats:txt pdf
Obsoleted by:RFC 2790
Status:PROPOSED STANDARD
This memo defines a MIB for use with managing host systems. The term"host" is construed to mean any computer that communicates with other similar computers attached to the internet and that is directly used by one or more human beings. Although this MIB does not necessarily apply to devices whose primary function is communications services(e.g., terminal servers, routers, bridges, monitoring equipment), such relevance is not explicitly precluded. This MIB instruments attributes common to all internet hosts including, for example, both personal computers and systems that run variants of Unix.

RFC 1520 Exchanging Routing Information Across Provider Boundaries in the CIDR Environment
 
Authors:Y. Rekhter, C. Topolcic.
Date:September 1993
Formats:txt pdf
Status:HISTORIC
The purpose of this document is twofold. First, it describes various alternatives for exchanging inter-domain routing information across domain boundaries, where one of the peering domain is CIDR-capable and another is not. Second, it addresses the implications of running CIDR- capable inter-domain routing protocols (e.g., BGP-4, IDRP) on intra- domain routing. This memo provides information for the Internet community. It does not specify an Internet standard.
 
RFC 1521 MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies
 
Authors:N. Borenstein, N. Freed.
Date:September 1993
Formats:txt pdf ps
Obsoletes:RFC 1341
Obsoleted by:RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049
Updated by:RFC 1590
Status:DRAFT STANDARD
STD 11, RFC 822 defines a message representation protocol which specifies considerable detail about message headers, but which leaves the message content, or message body, as flat ASCII text. This document redefines the format of message bodies to allow multi-part textual and non-textual message bodies to be represented and exchanged without loss of information. This is based on earlier work documented in RFC 934 and STD 11, RFC 1049, but extends and revises that work. Because RFC 822 said so little about message bodies, this document is largely orthogonal to (rather than a revision of) RFC822.

In particular, this document is designed to provide facilities to include multiple objects in a single message, to represent body text in character sets other than US-ASCII, to represent formatted multi- font text messages, to represent non-textual material such as images and audio fragments, and generally to facilitate later extensions defining new types of Internet mail for use by cooperating mail agents.

This document does NOT extend Internet mail header fields to permit anything other than US-ASCII text data. Such extensions are the subject of a companion document [RFC-1522].

This document is a revision of RFC 1341. Significant differences from RFC 1341 are summarized in Appendix H.

 
RFC 1522 MIME (Multipurpose Internet Mail Extensions) Part Two: Message Header Extensions for Non-ASCII Text
 
Authors:K. Moore.
Date:September 1993
Formats:txt pdf
Obsoletes:RFC 1342
Obsoleted by:RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049
Status:DRAFT STANDARD
This memo describes an extension to the message format defined in RFC1521 [1], to allow the representation of character sets other thanASCII in RFC 822 (STD 11) message headers. The extensions described were designed to be highly compatible with existing Internet mail handling software, and to be easily implemented in mail readers that support RFC 1521.
 
RFC 1523 The text/enriched MIME Content-type
 
Authors:N. Borenstein.
Date:September 1993
Formats:txt pdf
Obsoleted by:RFC 1563, RFC 1896
Status:INFORMATIONAL
MIME [RFC-1341, RFC-1521] defines a format and general framework for the representation of a wide variety of data types in Internet mail.This document defines one particular type of MIME data, the text/enriched type, a refinement of the "text/richtext" type defined in RFC 1341. The text/enriched MIME type is intended to facilitate the wider interoperation of simple enriched text across a wide variety of hardware and software platforms.
 
RFC 1524 A User Agent Configuration Mechanism For Multimedia Mail Format Information
 
Authors:N. Borenstein.
Date:September 1993
Formats:txt pdf
Status:INFORMATIONAL
This memo suggests a file format to be used to inform multiple mail reading user agent programs about the locally-installed facilities for handling mail in various formats. The mechanism is explicitly designed to work with mail systems based Internet mail as defined byRFC's 821 (STD 10), 822 (STD 11), 934, 1049 (STD 11), 1113, and theMultipurpose Internet Mail Extensions, known as MIME. However, with some extensions it could probably be made to work for X.400-based mail systems as well. The format and mechanism are proposed in a manner that is generally operating-system independent. However, certain implementation details will inevitably reflect operating system differences, some of which will have to be handled in a uniform manner for each operating system. This memo makes such situations explicit, and, in an appendix, suggests a standard behavior under the UNIX operating system.
 
RFC 1525 Definitions of Managed Objects for Source Routing Bridges
 
Authors:E. Decker, K. McCloghrie, P. Langille, A. Rijsinghani.
Date:September 1993

Obsoletes:RFC 1286
Status:HISTORIC
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP based internets. In particular, it defines objects for managing source routing and source routing transparent bridges. These bridges are also required to implement relevant groups in the Bridge MIB. [STANDARDS-TRACK]
 
RFC 1526 Assignment of System Identifiers for TUBA/CLNP Hosts
 
Authors:D. Piscitello.
Date:September 1993
Formats:txt pdf
Status:INFORMATIONAL
This document describes conventions whereby the system identifier portion of an RFC 1237 style NSAP address may be guaranteed uniqueness within a routing domain for the purpose of autoconfiguration in TUBA/CLNP internets. The mechanism is extensible and can provide a basis for assigning system identifiers in a globally unique fashion.
 
RFC 1527 What Should We Plan Given the Dilemma of the Network?
 
Authors:G. Cook.
Date:September 1993
Formats:txt pdf
Status:INFORMATIONAL
Early last year, as the concluding effort of an 18 month appointment at the US Congress Office of Technology Assessment (OTA), I drafted a potential policy framework for Congressional action on the NationalResearch and Education Network (NREN).

The Internet community needs to be asking what the most important policy issues facing the network are. And given agreement on any particular set of policy issues, the next thing we should be asking is, what would be some of the political choices that would follow forCongress to make?

It is unfortunate that this was never officially done for or by theCongress by OTA. What we have as a result is network policy making being carried out now by the Science Subcommittee on the House side in consultation with a relatively small group of interested parties.The debate seems to be more focused on preserving turf than on any sweeping understanding of what the legislation is doing. That is unfortunate.

In the hope that it may contain some useful ideas, I offer a shortened version of the suggested policy draft as information for the Internet community.

 
RFC 1528 Principles of Operation for the TPC.INT Subdomain: Remote Printing -- Technical Procedures

The document describes different approaches to resource recovery for remote printer server sites and includes discussions of issues pertaining to auditing, security, and denial of access. This memo provides information for the Internet community. It does not specify an Internet standard.
 
RFC 1530 Principles of Operation for the TPC.INT Subdomain: General Principles and Policy
 
Authors:C. Malamud, M. Rose.
Date:October 1993
Formats:txt pdf
Status:INFORMATIONAL
This document defines the initial principles of operation for the tpc.int subdomain, a collection of service listings accessible over the Internet infrastructure through an administered namespace contained within the Domain Name System [1,2].

This document is informational and applies only to those Internet sites that choose to register themselves within the tpc.int subdomain. The tpc.int subdomain is organized as a cooperative of the sites that provide access within the context of the subdomain.Policy for the subdomain is set by a board responsible to the cooperative.

The primary purpose of the tpc.int subdomain is to provide transparent mapping between general-purpose computers on the Internet and special-purpose devices directly connected to the telephone network. Initially, a remote printing service is defined [3,4] which ties together G3-compatible facsimile devices on the telephone network with users of electronic mail in the Internet and associated message-handling domains connected to the Internet by application- layer gateways.

It should be noted that remote printer gateways have long been technically feasible and have become an integral part of many individual networks. The tpc.int subdomain integrates individual sites into a common namespace, transforming remote printing from a single-site, value-added service into an integral transparent service in the global Internet.

 
RFC 1531 Dynamic Host Configuration Protocol
 
Authors:R. Droms.
Date:October 1993
Formats:txt pdf
Obsoleted by:RFC 1541
Status:PROPOSED STANDARD
The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing configuration information to hosts on a TCP/IP network.DHCP is based on the Bootstrap Protocol (BOOTP) [7], adding the capability of automatic allocation of reusable network addresses and additional configuration options [19]. DHCP captures the behavior ofBOOTP relay agents [7, 23], and DHCP participants can interoperate with BOOTP participants [9].
 
RFC 1532 Clarifications and Extensions for the Bootstrap Protocol
 
Authors:W. Wimer.
Date:October 1993
Formats:txt pdf
Obsoleted by:RFC 1542
Updates:RFC 0951
Status:PROPOSED STANDARD
Some aspects of the BOOTP protocol were rather loosely defined in its original specification. In particular, only a general description was provided for the behavior of "BOOTP relay agents" (originally called BOOTP forwarding agents"). The client behavior description also suffered in certain ways. This memo attempts to clarify and strengthen the specification in these areas.

In addition, new issues have arisen since the original specification was written. This memo also attempts to address some of these.

 
RFC 1533 DHCP Options and BOOTP Vendor Extensions
 
Authors:S. Alexander, R. Droms.
Date:October 1993
Formats:txt pdf
Obsoletes:RFC 1497, RFC 1395, RFC 1084, RFC 1048
Obsoleted by:RFC 2132
Status:PROPOSED STANDARD
The Dynamic Host Configuration Protocol (DHCP) [1] provides a framework for passing configuration information to hosts on a TCP/IP network. Configuration parameters and other control information are carried in tagged data items that are stored in the "options" field of the DHCP message. The data items themselves are also called"options."

This document specifies the current set of DHCP options. This document will be periodically updated as new options are defined.Each superseding document will include the entire current list of valid options.

All of the vendor information extensions defined in RFC 1497 [2] may be used as DHCP options. The definitions given in RFC 1497 are included in this document, which supersedes RFC 1497. All of theDHCP options defined in this document, except for those specific toDHCP as defined in section 9, may be used as BOOTP vendor information extensions.

RFC 1539 The Tao of IETF - A Guide for New Attendees of the Internet Engineering Task Force
 
Authors:G. Malkin.
Date:October 1993
Formats:txt pdf
Obsoletes:RFC 1391
Obsoleted by:RFC 1718
Status:INFORMATIONAL
Over the last two years, the attendance at Internet Engineering TaskForce (IETF) Plenary meetings has grown phenomenally. Approximately38% of the attendees are new to the IETF at each meeting. About 33% of those go on to become regular attendees. When the meetings were smaller, it wasn't very difficult for a newcomer to get to know people and get into the swing of things. Today, however, a newcomer meets many more new people, some previously known only as the authors of Request For Comments (RFC) documents or thought provoking email messages.

The purpose of this For Your Information (FYI) RFC is to explain to the newcomers how the IETF works. This will give them a warm, fuzzy feeling and enable them to make the meeting more productive for everyone. This FYI will also provide the mundane bits of information which everyone who attends an IETF meeting should know.

Authors:C. Partridge, T. Mendez, W. Milliken.
Date:November 1993
Formats:txt pdf
Status:INFORMATIONAL
This RFC describes an internet anycasting service for IP. The primary purpose of this memo is to establish the semantics of an anycasting service within an IP internet. Insofar as is possible, this memo tries to be agnostic about how the service is actually provided by the internetwork. This memo describes an experimental service and does not propose a protocol. This memo is produced by the Internet Research Task Force (IRTF).
 
RFC 1547 Requirements for an Internet Standard Point-to-Point Protocol
 
Authors:D. Perkins.
Date:December 1993
Formats:txt pdf
Status:INFORMATIONAL
This document discusses the evaluation criteria for an InternetStandard Data Link Layer protocol to be used with point-to-point links. Although many industry standard protocols and ad hoc protocols already exist for the data link layer, none are both complete and sufficiently versatile to be accepted as an InternetStandard. In preparation to designing such a protocol, the features necessary to qualify a point-to-point protocol as an InternetStandard are discussed in detail. An analysis of the strengths and weaknesses of several existing protocols on the basis of these requirements demonstrates the failure of each to address key issues.

Historical Note: This was the design requirements document datedJune 1989, which was followed for RFC-1134 through the present.It is now published for completeness and future guidance.

 
RFC 1548 The Point-to-Point Protocol (PPP)
 
Authors:W. Simpson.
Date:December 1993
Formats:txt pdf
Obsoletes:RFC 1331
Obsoleted by:RFC 1661
Updated by:RFC 1570
Status:DRAFT STANDARD
The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP is comprised of three main components:

1. A method for encapsulating multi-protocol datagrams.

2. A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection.

3. A family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.

This document defines the PPP organization and methodology, and thePPP encapsulation, together with an extensible option negotiation mechanism which is able to negotiate a rich assortment of configuration parameters and provides additional management functions. The PPP Link Control Protocol (LCP) is described in terms of this mechanism.

This document is the product of the Point-to-Point Protocol WorkingGroup of the Internet Engineering Task Force (IETF). Comments should be submitted to the ietf-ppp@ucdavis.edu mailing list.

RFC 1560 The MultiProtocol Internet
 
Authors:B. Leiner, Y. Rekhter.
Date:December 1993
Formats:txt pdf
Status:INFORMATIONAL
This document was prepared by the authors on behalf of the InternetArchitecture Board (IAB). It is offered by the IAB to stimulate discussion.

There has recently been considerable discussion on two topics:MultiProtocol approaches in the Internet and the selection of a next generation Internet Protocol. This document suggests a strawman position for goals and approaches for the IETF/IESG/IAB in these areas. It takes the view that these two topics are related, and proposes directions for the IETF/IESG/IAB to pursue.

In particular, it recommends that the IETF/IESG/IAB should continue to be a force for consensus on a single protocol suite and internet layer protocol. The IETF/IESG/IAB should:

- maintain its focus on the TCP/IP protocol suite,

- work to select a single next-generation internet protocol and develop mechanisms to aid in transition from the current IPv4, and

- continue to explore mechanisms to interoperate and share resources with other protocol suites within the Internet.

 
RFC 1561 Use of ISO CLNP in TUBA Environments
 
Authors:D. Piscitello.
Date:December 1993
Formats:txt pdf
Status:EXPERIMENTAL
This memo specifies a profile of the ISO/IEC 8473 Connectionless-modeNetwork Layer Protocol (CLNP, [1]) for use in conjunction with RFC1347, TCP/UDP over Bigger Addresses (TUBA, [2]). It describes the use of CLNP to provide the lower-level service expected byTransmission Control Protocol (TCP, [3]) and User Datagram Protocol(UDP, [4]). CLNP provides essentially the same datagram service asInternet Protocol (IP, [5]), but offers a means of conveying bigger network addresses (with additional structure, to aid routing).

While the protocols offer nearly the same services, IP and CLNP are not identical. This document describes a means of preserving the semantics of IP information that is absent from CLNP while preserving consistency between the use of CLNP in Internet and OSI environments.This maximizes the use of already-deployed CLNP implementations.

RFC 1577 Classical IP and ARP over ATM
 
Authors:M. Laubach.
Date:January 1994
Formats:txt pdf
Obsoleted by:RFC 2225
Status:PROPOSED STANDARD
This memo defines an initial application of classical IP and ARP in an Asynchronous Transfer Mode (ATM) network environment configured as a Logical IP Subnetwork (LIS) as described in Section 3. This memo does not preclude the subsequent development of ATM technology into areas other than a LIS; specifically, as single ATM networks grow to replace many ethernet local LAN segments and as these networks become globally connected, the application of IP and ARP will be treated differently. This memo considers only the application of ATM as a direct replacement for the "wires" and local LAN segments connectingIP end-stations ("members") and routers operating in the "classical"LAN-based paradigm. Issues raised by MAC level bridging and LAN emulation are beyond the scope of this paper.

This memo introduces general ATM technology and nomenclature.Readers are encouraged to review the ATM Forum and ITU-TS (formerlyCCITT) references for more detailed information about ATM implementation agreements and standards.

RFC 1582 Extensions to RIP to Support Demand Circuits
 
Authors:G. Meyer.
Date:February 1994
Formats:txt pdf
Status:PROPOSED STANDARD
Running routing protocols on connection oriented Public DataNetworks, for example X.25 packet switched networks or ISDN, can be expensive if the standard form of periodic broadcasting of routing information is adhered to. The high cost arises because a connection has to all practical intents and purposes be kept open to every destination to which routing information is to be sent, whether or not it is being used to carry user data.

Routing information may also fail to be propagated if the number of destinations to which the routing information is to be sent exceeds the number of channels available to the router on the Wide AreaNetwork (WAN).

This memo defines a generalized modification which can be applied toBellman-Ford (or distance vector) algorithm information broadcasting protocols, for example IP RIP, Netware RIP or Netware SAP, which overcomes the limitations of the traditional methods described above.

The routing protocols support a purely triggered update mechanism on demand circuits on WANs. The protocols run UNMODIFIED on LANs or fixed point-to-point links.

Routing information is sent on the WAN when the routing database is modified by new routing information received from another interface.When this happens a (triggered) update is sent to a list of destinations on other WAN interfaces. Because routing protocols are datagram based they are not guaranteed to be received by the peer router on the WAN. An acknowledgement and retransmission mechanism is provided to ensure that routing updates are received.

The WAN circuit manager advises the routing applications on the reachability and non-reachability of destinations on the WAN.

 
RFC 1583 OSPF Version 2
 
Authors:J. Moy.
Date:March 1994
Formats:txt pdf ps
Obsoletes:RFC 1247
Obsoleted by:RFC 2178
Status:DRAFT STANDARD
This memo documents version 2 of the OSPF protocol. OSPF is a link-state routing protocol. It is designed to be run internal to a single Autonomous System. Each OSPF router maintains an identical database describing the Autonomous System's topology. From this database, a routing table is calculated by constructing a shortest- path tree.

OSPF recalculates routes quickly in the face of topological changes, utilizing a minimum of routing protocol traffic. OSPF provides support for equal-cost multipath. Separate routes can be calculated for each IP Type of Service. An area routing capability is provided, enabling an additional level of routing protection and a reduction in routing protocol traffic. In addition, all OSPF routing protocol exchanges are authenticated.

OSPF Version 2 was originally documented in RFC 1247. The differences between RFC 1247 and this memo are explained in AppendixE. The differences consist of bug fixes and clarifications, and are backward-compatible in nature. Implementations of RFC 1247 and of this memo will interoperate.

RFC 1584 Multicast Extensions to OSPF
 
Authors:J. Moy.
Date:March 1994
Formats:txt pdf ps
Status:HISTORIC
This memo documents enhancements to the OSPF protocol enabling the routing of IP multicast datagrams. In this proposal, an IP multicast packet is routed based both on the packet's source and its multicast destination (commonly referred to as source/destination routing). As it is routed, the multicast packet follows a shortest path to each multicast destination. During packet forwarding, any commonality of paths is exploited; when multiple hosts belong to a single multicast group, a multicast packet will be replicated only when the paths to the separate hosts diverge.

OSPF, a link-state routing protocol, provides a database describing the Autonomous System's topology. A new OSPF link state advertisement is added describing the location of multicast destinations. A multicast packet's path is then calculated by building a pruned shortest-path tree rooted at the packet's IP source. These trees are built on demand, and the results of the calculation are cached for use by subsequent packets.

The multicast extensions are built on top of OSPF Version 2. The extensions have been implemented so that a multicast routing capability can be introduced piecemeal into an OSPF Version 2 routing domain. Some of the OSPF Version 2 routers may run the multicast extensions, while others may continue to be restricted to the forwarding of regular IP traffic (unicasts).
