OSI environments, and dual environments.  This specification was
developed by the IS-IS working group of the Internet Engineering Task
Force.  [STANDARDS-TRACK]

small change to the way routers generate one type of ICMP message.  For
a path that passes through a router that has not been so changed, this
technique might not discover the correct Path MTU, but it will always
choose a Path MTU as accurate as, and in many cases more accurate than,
the Path MTU that would be chosen by current practice.  [STANDARDS-

                              A Model for Routing in the Internet

This RFC proposes a model for describing routing within the Internet.

The model is an adaptation of the "OSI Routeing Framework".  This memo
does not specify an Internet standard.


1135    Reynolds     Dec 89   The Helminthiasis of the Internet

This memo takes a look back at the helminthiasis (infestation with, or
disease caused by parasitic worms) of the Internet that was unleashed
the evening of 2 November 1988.  This RFC provides information about an
event that occurred in the life of the Internet.  This memo does not
specify any standard.

This document provides a glimpse at the infection, its festering, and
cure.  The impact of the worm on the Internet community, ethics
statements, the role of the news media, crime in the computer world, and
future prevention is discussed.  A documentation review presents four
publications that describe in detail this particular parasitic computer
program.  Reference and bibliography sections are also included.

                              Datagrams Over Point-to-Point Links

This proposal is the product of the Point-to-Point Protocol Working
Group of the Internet Engineering Task Force (IETF).  Comments on this
memo should be submitted to the IETF Point-to-Point Protocol Working
Group chair by January 15, 1990.  Comments will be reviewed at the
February 1990 IETF meeting, with the goal of advancing PPP to draft
standard status.  [STANDARDS-TRACK]


1133    Yu           Nov 89   Routing between the NSFNET and the DDN

This document is a case study of the implementation of routing between
the NSFNET and the DDN components (the MILNET and the ARPANET).  We hope
that it can be used to expand towards interconnection of other
Administrative Domains.  We would welcome discussion and suggestions
about the methods employed for the interconnections.  No standards are
specified in this memo.

This document specifies a standard method of encapsulating 802.2 packets
on networks supporting Novell's Internet Packet Exchange Protocol (IPX).
It obsoletes earlier documents detailing the transmission of Internet

packets over IPX networks.  It differs from these earlier documents in
that it allows for the transmission of multiple network protocols over
IPX and for the transmission of packets through IPX bridges.


1131    Moy          Oct 89   The OSPF Specification

This RFC is the specification of the Open Shortest Path First (OSPF)
Internet routing protocol.  OSPF is in the class of Internal Gateway
Protocols (IGPs) for distributing routing information between gateways
of a single Autonomous System.  This routing protocol is based on the
link-state approach (in contrast to the distance-vector approach).  This
specification was developed by the OSPF Working Group of the Internet
Engineering Task Force.  [STANDARDS-TRACK]

1129    Mills        Oct 89   Internet Time Synchronization:
                              the Network Time Protocol

This memo describes the Network Time Protocol (NTP) designed to
distribute time information in a large, diverse internet system
operating at speeds from mundane to lightwave.  It uses a returnable-
time architecture in which a distributed subnet of time servers
operating in a self-organizing, hierarchical, master-slave configuration
synchronizes local clocks within the subnet and to national time
standards via wire or radio.  The servers can also redistribute time
information within a network via local routing algorithms and time
daemons.

The architectures, algorithms and protocols which have evolved to NTP
over several years of implementation and refinement are described in
this paper.  The synchronization subnet which has been in regular
operation in the Internet for the last several years is described along
with performance data which shows that timekeeping accuracy throughout
most portions of the Internet can be ordinarily maintained to within a
few tens of milliseconds, even in cases of failure or disruption of
clocks, time servers or networks.

This memo describes the Network Time Protocol in RFC-1119.

1128    Mills        Oct 89   Measured Performance of the Network Time
                              Protocol in the Internet System

This paper describes a series of experiments involving over 100,000
hosts of the Internet system and located in the U.S., Europe and the
Pacific.  The experiments are designed to evaluate the availability,
accuracy and reliability of international standard time distribution
using the DARPA/NSF Internet and the Network Time Protocol (NTP), which
is specified in RFC-1119.  NTP is designed specifically for use in a
large, diverse internet system operating at speeds from mundane to
lightwave.  In NTP a distributed subnet of time servers operating in a
self-organizing, hierarchical, master-slave configuration exchange
precision timestamps in order to synchronize subnet clocks to each other
and national time standards via wire or radio.

The experiments are designed to locate Internet hosts and gateways that
provide time by one of three time distribution protocols and evaluate
the accuracy of their indications.  For those hosts that support NTP,
the experiments determine the distribution of errors and other
statistics over paths spanning major portions of the globe.  Finally,
the experiments evaluate the accuracy and reliability of precision
timekeeping using NTP and typical Internet paths involving DARPA, NSFNET
and other agency networks.  The experiments demonstrate that timekeeping
accuracy throughout most portions of the Internet can be ordinarily
maintained to within a few tens of milliseconds, even in cases of
failure or disruption of clocks, time servers or networks.

This memo does not specify a standard.

1126    Little       Oct 89   Goals and Functional Requirements for
                              Inter-Autonomous System Routing

This document describes the functional requirements for a routing
protocol to be used between autonomous systems.  This document is
intended as a necessary precursor to the design of a new inter-
autonomous system routing protocol and specifies requirements for the
Internet applicable for use with the current DoD IP, the ISO IP, and
future Internet Protocols.  It is intended that these requirements will
form the basis for the future development of a new inter-autonomous
systems routing architecture and protocol. This memo does not specify a
standard.

1125    Estrin       Nov 89   Policy Requirements for Inter

The purpose of this memo is to focus discussion on particular problems
in the Internet and possible methods of solution.  No proposed solutions
in this document are intended as standards for the Internet.  Rather, it
is hoped that a general consensus will emerge as to the appropriate
solution to such problems, leading eventually to the development and
adoption of standards.


1124    Leiner       Sep 89   Policy Issues in Interconnecting Networks

To support the activities of the Federal Research Internet Coordinating
Committee (FRICC) in creating an interconnected set of networks to serve
the research community, two workshops were held to address the technical
support of policy issues that arise when interconnecting such networks.
Held under the suspices of the Internet Activities Board at the request
of the FRICC, and sponsored by NASA through RIACS, the workshops
addressed the required and feasible technologies and architectures that
could be used to satisfy the desired policies for interconnection.  The
purpose of this RFC is to report the results of these workshops.

                              Specification and Implementation

This document describes the Network Time Protocol (NTP), specifies its
formal structure and summarizes information useful for its
implementation.  NTP provides the mechanisms to synchronize time and
coordinate time distribution in a large, diverse internet operating at
rates from mundane to lightwave.  It uses a returnable-time design in
which a distributed subnet of time servers operating in a self-
organizing, hierarchical-master-slave configuration synchronizes local
clocks within the subnet and to national time standards via wire or
radio.  The servers can also redistribute reference time via local
routing algorithms and time daemons.  [STANDARDS-TRACK]
