IAB MESSAGE

A. IP SECURITY OPTION

The Host Requirements RFC cites RFC-1108 as a reference for the
IP Security Option (PSO). Unfortunately, as a number of vendors
to the US Department of Defense have discovered, RFC-1108 has
never been published.

[The RFC Editor has a strict policy of never assigning an RFC
number until the RFC is entirely ready for publication. He made
an exception at the request of the Host Requirements RFC editor,
assigning the number 1108 to an IPSO draft that was (almost)
completely approved. Unfortunately, that IPSO draft
subsequently ran into a brick wall somewhere in the vicinity of
Washington, DC]

As the result of significant efforts by IAB members Steve Kent
and Vint Cerf, the IPSO specification has at least been approved
by all relevant parties, and has been published as an Internet
Draft:

Title : U.S. Department of Defense Security Options for
the Internet Protocol
Author(s) : Stephen Kent
Filename : draft-ietf-ahwgipso-ipso-00.txt

The IESG and IAB will move it into the standards track as soon
as there is sufficient opportunity for community comment. AT
LAST, RFC-1108 will become a reality.

Completion of the IPSO specification is not the end of the road,
however. For historical reasons, IPSO is oriented completely to
US Department of Defense security. This is insufficient for the
modern Internet, for two reasons.

(1) There is a requirement to support corporate security
needs.

(2) The Internet is now international in scope, and a
US-centric solution is no longer adequate.

The IETF and the IRTF are continuing to pursue these broader
issues. This work is led by the IETF Security Area Director
Steve Crocker (crocker@tis.com) and by Steve Kent
(kent@bbn.com), chair of the Privacy and Security Research
Group.

INTERNET PROJECTS
-----------------

BARRNET
-------

Two new 56 kbps connections and one dial-in connection were added
in March, bringing the total number of connected members to
seventy-nine.

Installation was completed on a new T1 interconnection between the
California State University Network and BARRNet. The new link runs
between Stanford University and San Francisco State University. The
connection, under a new "Midlevel Network Connection Service
Agreement" that is nearing completion, will be one of two between
CSUNet and BARRNet (the other is already in place between UC Davis
and Sacramento State University).

Plans are proceeding for the addition of new T1 backbone circuits,
including a link to a new hub site at Santa Clara University, the
completion of a redundantloop through San Francisco (utilizing the
Stanford-SF State connection and a new line between SF State and UC
San Francisco), and a circuit between Stanford and the Naval
Postgraduate School in Monterey (replacing an existing 56k line to
the Monterey Bay Aquarium Research Institute).

A demonstration of the new T3 backbone was conducted between
BARRNet and the National Net'91 Conference in Washington DC March
20-22. The demonstration ran an X-windows graphical database
interface, called Image Query, that made use ofseveral different
24-bit color image databases located both at Stanford and at
Berkeley. The Stanford database copy was accessed via the new T3
ANS/NSFNET backbone while the Berkeley database was accessed via
the older T1 NSFNET backbone. The demo showed very clearly the
need for at least T3 bandwidth if such applications are going to be
practical. The difference in screen drawing time was at least 10 to
1 faster over the T3 link. This showed both the availability of
existing applications and the ability of existing platforms to take
advantage of the higher speed.

BOLT BERANEK AND NEWMAN INC.
----------------------------

Terrestrial Wideband Network (TWBNet) and ST/IP Gateway

In February, DARPA directed BBN and PSI to reconfigure the TWBNet
topology to minimize line costs while maintaining site
connectivity. Accordingly, during March, a T1 circuit was
implemented between the Albuquerque WPS and the Los Angeles WPS,
and the T1 circuit between BBN and Mobile was removed. In
addition, the gateway at NCSA was removed and the one at Ft.
Leavenworth was disconnected. The latter will remain at the site
until it is either reconnected or needed elsewhere. The current
TWBNet backbone topology is shown below (not drawn to scale):

BBN
/
NY
/
LA ------------ Chicago ----- Pittsburgh ---- Wash DC
\
\
\--- Albuquerque -------------Mobile

In February and March there were ten video conferences. Seven were
between two sites and three involved four sites. Two of the four
site conferences were associated with major demonstrations of video
conferencing and interactive multimedia applications over wide area
networks. These conferences linked sites in Europe and the United
States. The video conferencing was routed through the video
"hublet" located at BBN. For the latter half of February and the
beginning of March the TWBNet was used extensively for testing
conferencing in preparation for these demonstrations. Included in
the eight other conferences were a meeting of the Inter-Domain
Policy Routing Working Group and three demonstrations of
conferencing technology. Participants included Mark Pullen, Peter
Kirstein, and Danny Cohen.

Inter-Domain Policy Routing

Throughout most of March, we devoted the majority of our time to
experimenting with our IDPR prototype on DARTNET. Our experiments
consisted of sending traffic between BBN and ISI over multiple
paths and through domains of differing transit policies. As
DARTNET has no alternate paths between nodes, we used the
Terrestrial Wideband Network in conjunction with DARTNET to provide
a richer network topology.

Westine [Page 8]

Internet Monthly Report March 1991

We experimented with restrictive transit policies, changes in
topology, and changes in transit policy, and observed how the
routes changed accordingly. Our data traffic consisted of a TELNET
session between SPARCstations at BBN and ISI. At this point, we
were not concerned with high volumes of traffic, but rather with
how the routes traversed by the TELNET traffic adapted to the
changing policies and connectivity. Satisfied with the results of
our experiments, we presented a demonstration to Ira Richer during
his visit to BBN at the end of March.

Currently, we are putting together a user's guide for IDPR, and we
are working on a white paper describing our approach to policy-
based resource allocation.

Internet O&M / ICBNet Infrastructure

New software was installed in all of the European ICBNet gateways
and most of the TWBNet gateways during February and March. The new
software relieves various CPU and memory-allocation bottlenecks in
the gateways, providing the capacity to store EGP-derived routes to
up to 3000 external networks.

The new gateway software release also supports automatic fallback
paths to the US Internet for European ICBNet sites, and includes
monitoring and control improvements. The primary backup path,
which became operational in March, provides a route to the US via
the 256 Kbps satellite circuit connecting the WPC ICBNet site in
Germany to the TWBNet POP at BBN. A secondary path, which will
become operational pending routing configuration changes to be made
by NTA, will provide a route to the US via the NTA ICBNet site's
NORDUnet connection.

The remaining TWBNet Butterfly gateways are scheduled to be
upgraded with the new software in early April.

A number of components associated with the 384 Kbps channel of the
US-UK "fat pipe" circuit were repaired by the circuit provider in
March. As of the end of the month, these repairs appear to have
eliminated chronic line-timing problems which had impacted US-UK
internet connectivity.

24x7 monitoring of the US-UK fat pipe connection was implemented by
BBN at the end of March.

CICNET
-------

At a meeting held on March 27, the CICNet Board of Directors
approved the appointment of E. Michael Staman as the new Chief
Executive of CICNet. Mike iscurrently Associate Vice President and
CIO at West Chester University, located in West Chester, PA. He
will join CICNet on a part time basis in April and will be full
time on July 1, 1991.

CICNet Assistant Director John Hankins participated in a conference
sponsored by the American College of Radiology on issues related to
networking and radiological research. John also attended the
National Net 91 Conference.

Paul Holbrook, Manager of Technical Services, attended the March
IETF meeting where he particiapted in a number of working groups
dealing with security issues.

by John Hankins <hankins@cic.net>

CORNELL
-------

Scott Brim and Jeff Honig participated in IETF Working Groups. The
Multicast OSPF Working Group reached agreement on extensions to
OSPF to support multicasting. In the BGP Working Group, we
presented five alternative designs for multicast support which had
various advantages and disadvantages. The group was not able to
decide which one to adopt during the meeting, but through later
discussions we are on the verge of choosing one (basic reverse path
forwarding), after which prototype implementations can begin.

At the DARPA Networking PI meeting, Scott Brim gave a short talk on
the current status of multicast routing extensions to mainstream
routing protocols.

Gated:

Pattern matching code for route filtering based on BGP ASpath is
now integrated, but not tested; we are waiting for Dennis
Ferguson to finish his implementation of BGP3 and plan release
them together.

The Gatedaemon Project has a new address. Electronic mail to
the gated maintainers should be sent to gated@gated.cornell.edu
(the mailing list is gated-people@gated.cornell.edu). The
telephone number is +1-607-255-5510. Paper mail should be sent

FEDERATION OF AMERICAN RESEARCH NETWORKS (FARNET)
-------------------------------------------------

The following items were covered at a FARNET board meeting at the
conclusion ofNet-91 in Washington, DC:

FARNET plans to disseminate the strategic planning document to its
planning committee and membership for their review, comment, and
approval and that this process will be followed by public
dissemination.

FARNET is beginning to search for an executive director to
implement the programs it adopted at the last meeting.

The Spring meeting will be April 30 and May 1 in Austin, TX. Part
of the meeting will be devoted to a K-12 teachers' seminar. A
proposed agenda for this meeting should be forthcoming soon.

The August meeting will be be held in Bozeman, Montana on August
12-13.

Currently, FARNET is comprised of 28 member institutions.

Carlos Robles <roblesc@cerf.net>

HIGHER EDUCATION AUTHORITY NETWORK (HEANET)
-------------------------------------------

This is the Higher Education Authority Network, and consists of
seven university institutions in Ireland. These seven sites are
connected over low speed lines to the public packet-switched
network.

Westine [Page 11]

Internet Monthly Report March 1991

In February 1991, one of the sites (University College Dublin -
UCD) connected its campus network to the RIPE networks by means of
an X.25 connection over IXI to NIKHEF in Amsterdam. This offers
(nominal) 64K IP services between UCD and RIPE. Access to NSFNET
and other networks is available from EASInet via the gateway at
CERN.

GIGABIT NETWORKING

Greg Finn, Danny Cohen, and Bob Braden, attended the DARPA
Principal Investigator's meeting in Monterey, California, March
25-28, 1991 and Bob Braden chaired a session on DARTNET. Joyce
Reynolds attended the IETF meeting in St. Louis IETF, March 11-15.

ATOMIC

Greg Finn held discussions with Dr. Seitz of Caltech and his staff
on the MOSAIC processor, a VME host interface and its software
prototyping environment. A substantial amount of time was spent
reading the Caltech MOSAIC group's papers. Limited discussions
have taken place with others at ISI concerning feasible uses for
MOSAIC technology in packet filtering and possible use in video
applications.

INFRASTRUCTURE

Seven RFCs were published this month.

RFC 1208: Jacobsen, O., and D. Lynch, "A Glossary of
Networking Terms", Interop, Inc., March 1991.

RFC 120 the regionals). Walt presented his draft OSI routing
architecture for the Network OSI Operations WG, which stirred up
lots of useful discussion. Walt and Bill also attended the PSTP
working group on OSI Registration to work on an NSAP structure and
usage for DDN.

Forrest Palmer presented a briefing to MITRE and sponsor personnel
on the SNMP protocol concepts and formats. Shari, Bill, and Walt
attended a demonstration and discussion of the BBN Integrated
Management Workstation (IMW) commissioned by DCA. This is an SNMP
and HMP based graphical net management tool for monitoring MIB I
nodes and Mailbridges. The IMW is being used by the Cambridge
monitoring center and the NearNet NOC.

Forrest Palmer worked with SAIC staff to establish their IDPR
experiments on the Internet Engineering Testbed. Forrest installed
an X-kernel implementation, which has helped us expand the testbed
by utilizing old Sun-3/50 workstations. Forrest is also busy
planning for upgrading the 16 Sun-3s to SunOS 4.1.1 and SunNet OSI
7.0. This upgrade requires coordination with the 10 experiments
running on the testbed. Mike Saintcross has been upgrading
hardware at the DCA portion of the I.E. Testbed to accomwith the SNMP, Performance Systems
International, March 1991.

One paper was published.

MULTIMEDIA CONFERENCING

To enable workstation-based conferencing on a wide scale across the
Internet, we need to integrate real-time services into the existing
IP infrastructure. An open question is what new mechanisms must be
added to provide real-time services. This question was discussed
extensively in the Connection-Oriented IP Working Group at the IETF
meeting in St. Louis, and on the sidelines at the DARPA Networking
Principal Investigators meeting in Monterey, where Steve Casner
gave a presentation on DARTnet Voice and Video. We expect the
DARTnet experiments to help answer this question over the next
year.

One such experiment is the integration of the ST-II protocol (RFC
1190) with the ISI/BBN teleconferencing system. Work is underway
to adapt the the packet voice program, VT, and the packet video
program, PVP, to use the ST-II socket interface that has been
implemented in the SunOS4.1 SPARCstation kernel by BBN. ST-II
replaces ST-I, which had previously been built into each of these
applications.

On the multisite conferencing front, PVP was enhanced to handle 5-
site conferences. For the Concept codec, which can simultaneously
display multiple video streams in quadrants on the video monitor,

Westine [Page 13]

Internet Monthly Report March 1991

the local site is normally displayed in one of the quadrants if the
number of sites is less than five. In a five-site conference, the
local image is replaced by the fourth remote site. For the
PictureTel codec, only one site can be displayed at a time but
multisite conferences are now possible using receiver-selected
floor control. Each site can independently choose which remote
site to view. We demonstrated to DARPA a conference of the three
sites ISI, BBN and RIACS.

MITRE Corporation
-----------------

Shari Galitzer, Bill Barns, and Walt Lazear attended the IETF
meetings in St. Louis, where OSI addressing was the hot topic (for
MITRE and the regionals). Walt presented his draft OSI routing
architecture for the Network OSI Operations WG, which stirred up
lots of useful discussion. Walt and Bill also attended the PSTP
working group on OSI Registration to work on an NSAP structure and
usage for DDN.

Westine [Page 14]

Internet Monthly Report March 1991

Walt and John McGuthry worked to establish CLNS routing on the
Testbed's cisco routers and Sun workstations. AlterNet and NSFNET
staff were involved and the month's-end result was successful
pinging to CERN (Switzerland) and the NSFNET NOC. We are awaiting
some fixes from cisco before OSI testing with NorduNet can proceed.
John is also converting the U. Wisconsin Argo OSI code to use the
GOSIP 2 NSAP format. His next task will be to port the Argo code
to run over the SunNet OSI 7.0 lower stack.

The Internet Management effort has obtained some much-needed demo
space and are working with facilities engineers to modernize the
space. We're extending the I.E. Testbed into the area with
twisted-pair Ethernet and starting to refurbish the power
conditioner and air conditioners. Next month we'll move systems
into place.

NNSC, UCAR/BOLT BERANEK and NEWMAN, INC.
----------------------------------------

Karen Roubicek attended the IETF in St. Louis, Missouri. Karen
participated ina workshop on Computer Networks in Radiology
Research sponsored by the NationalScience Foundation, National
Library of Medicine, National Cancer Institute andthe American
College of Radiology. Karen also attended the National Net'91
conference held in Washington, D.C.

The NNSC began distribution of the 9th issue of the NSF Network
News.

The NNSC distributed additions to chapters 2 and 5 of the Internet
Resource Guide.

The NNSC also began distribution of the NNSC Tour of the Internet.
The Internet Tour is available for anonymous ftp on NNSC.NSF.NET,
in the directory internet-tour, filename Internet-Tour.sit.hqx.
The Internet Tour README file is attached.

Tour of the Internet:

The Internet Tour is a HyperCard 2 stack for Macintosh computers.
(HyperCard 2 requires Macintosh system 6.0.5 or higher.) The three
Internet Tour files have been compressed using StuffIt 1.5.1, and
converted to binhex format. In order to use the files, you need to
reverse the process. To do this you need the Macintosh application
StuffIt 1.5.1. The files take up about 760k when converted to
their original format. (You'll need at least twice that much space

Westine [Page 15]

Internet Monthly Report March 1991

to do the conversion.)

FTP the file Internet-Tour.sit.hqx using a text option; then
transfer it to your Mac. Use StuffIt's "Decode binhex file" option
(on the Other menu). Thiscreates a new file in addition to the
original one: Internet-Tour.sit. Next choose "Open archive" from
StuffIt's File menu. Open Internet-Tour.sit, and click the
"Extract" button at the bottom. This will create three files:
Internet Tour, Internet Local Info, and Internet Tour doc.

NSF BACKBONE (Merit)
-------------------

The inbound packet count for March 1991 totaled 7,026,153,681
packets on the T1 infrastructure. This was an increase of 16.53%
over the February 1991 total of 6,029,601,114 inbound packets. As
of March, 2501 networks are announced via the NSFNET. Of that
total, 757 represent foreign networks, including the newest foreign
host location, the Netherlands.

Production traffic continues to be phased to the T3 infrastructure.
Routing for 37 nets now occurs on the T3 NSFNET. Planning
continues for the deployment of T3 to NSFNET sites. FDDI
interfaces deployed at Palo Alto, CA and Pittsburgh, PA were
instrumental in the demonstrations presented at NET '91.
Operational NSFNET traffic is routed via FDDI at Champaign-Urbana,
IL and San Diego, CA as well as Palo Alto and Pittsburgh.

National NET '91, "Towards a National Information Infrastructure,"
convened at Loews L'enfant Plaza Hotel in Washington, D.C. on March
20, 21 and 22. The NSFNET partnership provided T3 connectivity for
several demonstrations of supercomputing technology: MCI installed
the T3 circuit to the L'enfant Plaza and a T1 circuit between Ann
Arbor and L'enfant Plaza, IBM supplied the routers, and Merit
Network, Inc. was responsible for the local area network at at the
conference as well as the overall coordination of the facility
installation and demonstrations. Bob Stovall of the Merit Network
Systems Hardware Support group deployed and managed the LAN. Eric
Aupperle, President of Merit Network, Inc., Ellen Hoffman,
assistant to Aupperle, Laura Kelleher and Susan Calcari, of
Merit/NSFNET Information Services, and Elise Gerich of Merit/NSFNET
Internet Engineering attended this event on behalf of the NSFNET
project.

Glee Cady and Laura Kelleher represented Merit/NSFNET Information
Services at the Coalition for Networked Information (CNI) meeting

Internet Monthly Report March 1991

held in Washington, D.C. Kelleher and Cady are active in the
Directories and Resource Information Services working group, which
discussed questions of how to gather, store and access information.

Several representatives of Merit Network, Inc. attended the spring
meeting of the IETF in St. Louis, MO: Dale Johnson, manager of the
Merit Network Operations Center; Susan Hares, Elise Gerich, and
Dave Katz of Merit/NSFNET Internet Engineering; Allan Rubens, Glenn
McGregor, Chris Weider, and Bill Norton of Merit Network
Engineering; Pat Smith of Merit/NSFNET Information Services and
Dana Sitzler of the Merit Technical Support Group. In addition to
participating on the Network Information Services Infrastructure
working group, Smith attended the inaugural meeting of the User
Services Area Council, chartered to promote and encourage the
creative exchange of international user service needs and concepts.
Gerich presented the NSFNET status report, Norton gave an overview
of statistics gathering for the NSFNET, and Katz, Sitzler and
Weider chaired their respective working groups.

"Making Your NSFNET Connection Count" will be sponsored by
Merit/NSFNET Information Services in Ann Arbor, Michigan on May 20

UCL
----

An experiment in remote video data retrieval was carried out
between Bellcore and UCL. Michael Lesk made available a filesystem
holding a recording of a talk by Dave Clark from last year. This
was "played back" over the Internet to UCL. The audio was
acceptable, but the "video" (actually frame by frame NFS retrieval
from files) ran at about 1 per second. (Given the bandwidth of the
link, this was at about the limit for 31kbyte frame sizes). The
"talk" was eduacational.

Jon Crowcroft gave a talk at Europarc on the UCL multi-media
conferencing work (work sponsored by both DARPA and RACE).

Under the chair of Steve Kille, the OSI Directory Group have now
produced a number of IETF drafts:

This document is a first cut at describing an overall strategy
for deploying an OSI Directory on the Internet. This is a draft
document, and does not carry any implications of agreement on

Overall plan of the IETF Working Group on OSI Directories
(OSI-DS) to build an Internet Directory using X.500
S.E. Kille
February 1991
Abstract:

The IETF has established a Working Group on OSI Directory
Services (IETF-OSI-DS). A major component of the initial work of
this group is to establish a technical framework for
establishing a Directory Service on the Internet, making use of
the X.500 protocols and services [CCI88b]. This document
summarises the plan established by the working group to achieve
this, and describes a number of RFCs which the working group
will write in order to establish the technical framework.

This document has now been submitted as an RFC.

"An Interim Approach to use of Network Addresses"
S.E. Kille
draft-ucl-kille-networkaddresses-02.txt, .ps
January 1991
Abstract:

The OSI Directory specifies an encoding of Presentation Address,
which utilises OSI Network Addresses as defined in the OSI
Network Layer standards [CCI88 ] [ISO87a ]. The OSI Directory,
and any OSI application utilising the OSI Directory must be able
to deal with these Network Addresses. Currently, most
environments cannot cope with them. It is not reasonable or

Westine [Page 19]

Internet Monthly Report March 1991

desirable for groups wishing to investigate and use OSI
Applications in conjunction with the OSI Directory to have to
wait for the lower layers to sort out. This note is a proposal
for mechanisms to utilise Network Addresses.

A String encoding of Presentation Address
draft-ucl-kille-presentationaddress-02.txt, ps

Abstract:

There are a number of environments where a simple string
encoding of Presentation Address is desirable. This
specification defines such a representation.

Domains and X.500
S.E. Kille
March 1991
Abstract:

This INTERNET--DRAFT considers X.500 in relation to Internet and
UK Domains. A basic model of X.500 providing a higher level and
more descriptive naming structure is emphasised. In addition, a
mapping of domains onto X.500 is proposed, which gives a range
of new management and user facilities over and above those
currently available. This specification proposes an
experimental new mechanism to access and manage domain
information on the Internet and in the UK Academic Community.

Using the OSI Directory to achieve User Friendly Naming
S.E. Kille
March 1991
Abstract:

The OSI Directory has user friendly naming as a goal. A simple
minded usage of the directory does not achieve this. Two aspects
not achieved are:

Westine [Page 20]

Internet Monthly Report March 1991

o A user oriented notation
o Guessability

This proposal sets out some conventions for representing names
in a friendly manner, and shows how this can be used to achieve
really friendly naming. This then leads to a specification of a
standard format for representing names, and to procedures to
resolve them.

Replication Requirement to provide an Internet Directory
using X.500
S.E. Kille
March 1991
draft-ietf-osids-replication-01.txt, .ps
Abstract:

A companion document discussed an overall framework for
deploying X.500 on the Internet [Kil90 ]. This document
considers certain deficiencies of the 1988 standard, which need
to be addressed before an effective open Internet Directory can
be established [CCI88 ]. The only areas considered are primary
problems, to which solutions must be found before a pilot can be
deployed. This INTERNET--DRAFT concerns itself with
deficiencies which can only be addressed by use of additional
protocol or procedures for distributed operation.

The COSINE and Internet X.500 Schema
Abstract:

This document suggests an X.500 Directory Schema, or Naming
Architecture, for use in the COSINE and Internet X.500 pilots.
The schema is independent of any specific implementation. As
well as indicating support for the standard object classes and
attributes, a large number of generally useful object classes
and attributes are also defined. An appendix to this document
includes a machine processable version of the schema

This document also proposes a mechanism for allowing the schema
to evolve in line with commonly held requirements. Proformas to
support this process are included.

Westine [Page 21]

Internet Monthly Report March 1991

It is important to note that this version of the document is a
draft, and comments on the updating mechanisms are particularly
welcome. Corrections and additions to the schema should now be
sent the list, as described within.

Replication and Distributed Operations extensions to provide
an Internet Directory using X.500
S.E. Kille
March 1991
Abstract:

Some requirements on extensions to X.500 are described in the
INTERNET--DRAFT [Kil90b ], in order to build an Internet
Directory as described in the INTERNET--DRAFT [Kil90a ]. This
document specifies a set of solutions to the problems raised.
These solutions are based on some work done for the QUIPU
implementation, and demonstrated to be effective in a number of
directory pilots. By documenting a de facto standard, rapid
progress can be made towards a full-scale pilot. These
procedures are an INTERIM approach. There are known
deficiencies, both in terms of manageability and scalability.
Transition to standard approaches are planned when appropriate
standards are available. This INTERNET--DRAFT will be obsoleted
at this point.

DSA Naming
S.E. Kille
March 1991
Abstract:

This INTERNET--DRAFT describes a few problems with DSA Naming as
currently deployed in pilot exercises, and suggests a new
approach. This approach is suggested for use in the Internet
Directory Pilot.

I believe this note to be an important step forward, as it
begins to evolve a clear model of a Directory Management Domain.

Internet Network Infrastructure Information In X.500
C. Weider
M. Knopper
March 1991
Abstract:

As the OSI Directory progresses into an operational structure
which is being increasingly used as a primary resource for
Directory information, it was percieved that having the Internet
Site Contacts and some limited network information in the
Directory would be immediately useful and would also provide the
preliminary framework for some distributed NIC functions. The
first section of this paper describes the schema used to contain
this information; the second section describes the DIT structure
built for this information.

UNIVERSITY OF DELAWARE
----------------------

1. In the light of recent discussions and further detail work, we
have further refined the design of our Highball high speed,
wide-area network, which is described in a recent technical
report. We are gearing up to etch some silicon and carve some
circuit traces and have hired some student grunts to devise
interface boards. We are in process of ordering node
processors (SPARCstations) and long leadtime components.

2. Charlie Boncelet, Paul Schragger and Dave Mills participated
in the DARPA Principal Investigator Meeting in rainy Monterey
and presented a briefing on the Highball Project.

Beginning this month, the Internet Monthly Report will contain a
section on the development of directory services that are for, or
effect, the Internet. We would like to encourage any organization
with related news on directory services development to use this
forum for publishing brief monthly news items. Current reports
include:

o IETF OSIDS & DISI Working Groups
o Field Operational X.500 Project
- ISI
- Merit
- PSI
- SRI
o North American Directory Forum
o PARADISE Project
o PSI WHITE PAGES PILOT

FOX -- FIELD OPERATIONAL X.500 PROJECT
--------------------------------------

The FOX project is a NSF and DARPA funded effort to provide a basis
for operational X.500 deployment in the NREN/Internet. This work
is being carried out at Merit, NSYERNet/PSI, SRI and ISI. ISI is
the main contractor and responsible for project oversight.

There are two primary thrusts of the FOX project:

1. X.500 Infrastructure

It is important that multiple interoperable platforms be available
for deployment. FOX plans to examine and test the interoperability
of the Quipu and NIST-X.500 (Custos) implementations, and DNANS-
X.500 if possible. In addition, FOX will explore X.500 interfaces
to conventional database systems (one target is Sybase), an
alternate OS platform (VM) for X.500 servers, and X-window based
user interfaces.

2. X.500 Applications

A long-range goal is to facilitate the use of X.500 for real
Internet applications. FOX will first focus on making network
infrastructure information available through X.500. This includes
network and AS site contacts, topology information, and the NIC
WHOIS service.

A centrally managed X.500 version will be the first phase of a
WHOIS service. Providing an X.500 version of a well-known widely-
used service should promote the use of X.500 by Internet users. In
addition, this effort will provide experience in designing X.500
applications. However, the managability of this scheme will be
short-lived, so the next step will be a design for a distributed
version of WHOIS.

Finally, it is critical for Internet X.500 efforts to be aligned
with directory service efforts that are ongoing in other
communities. FOX participants are involved in, or are otherwise
tracking these efforts, and information about FOX activities will
be publicly available.

ISI
---

ISI has been pushing to get the subcontracts completed and in
place, and has applied for a no-cost extension to the end of the
year for the FOX project. A similar extension will be made to
the subcontracts.

A telephone conference is scheduled during the week of April
15th.

Steve Hotz (hotz@ISI.EDU)

MERIT
-----

Several things have been happening at MERIT in conjunction with
the FOX project:

1: Merit has added another person to the X.500 crew: Richard
Conto, who will be working on FOX approximately 1/2 time.

2: ISODE 6.8i has been installed behind both of Merit's X.500
DSAs (directory servers). Merit operates a DSA on merit.edu
for the Merit staff and for network information, and also
a DSA on sprint.com for the Sprintmail X.400 gateway.

3: One Internet Draft has gone out from Merit's FOX project
team: the title is "Interim Schema for Network Infrastructure
Information in X.500". It contains a schema definition for
the Site Contacts portion of the directory information tree
(DIT - X.500's hierarchical name space). Two more IDs are
in progress: one on a long term DIT structure for network
information, and one on representing NSAPs in X.500.

4: Chris Weider of Merit is chairing a new X.500 related IETF
working group. The working group's name is "Directory
Information Services (pilot) Infra-structure Working Group"
or DISI for short. This working group is concerned with
developing an "Administrator's Guide" to Directory Services
through X.500, and with promoting the growth of the X.500
infrastructure.

5: Merit staff are using a Macintosh X.500 client written by
Mark Smith, Bryan Beecher, and Tim Howes of the University
of Michigan. This client is very nice, and uses Tim Howes'
lightweight "Dixie" protocol to talk to the DSA.

Westine [Page 26]

Internet Monthly Report March 1991

6: The X.500 directory is now used to maintain and generate the
production "aliases" file for the Sprintmail X.400 gateway.
Previously the aliases file was edited as a text file by
Sprint staff and updated manually. Now the Sprint staff and
some of their customers use an e-mail based command protocol
to modify the alias entries.

Marshall Rose (mrose@cheetah.ca.psi.com)

SRI
----

In order to provide an interim capability offering network
information via the Directory, SRI has begun the task of
replicating a subset of the WHOIS information in the Directory.
SRI has analyzed the WHOIS database and selected this subset.
Review by and discussion among the FOX project, participants
provided valuable feedback for finalizing the selected subset.
The development of a schema to support the WHOIS information is
underway and will be completed in early April.

SRI developed a program to produce a QUIPU EDB load file for
WHOIS individual information. It uses the pilotPerson object as
a prototype, as a means to anticipate potential data conversion
problems (e.g. size mismatches). Other more straightforward
conversions will be required, but the following two have been
identified as mismatches:

- WHOIS address field maximum greater than postalAddress

- reversed name ordering. Names in WHOIS are last name
first, whereas commonName suggests first name first.

The other WHOIS entities (e.g., computer, domain) will be
analyzed in a similar manner as part of the conversion process.

Ruth Lang attended the twentieth IETF held March 11-15 in St.
Louis. At the kick-off meeting of the Directory Information
Services (pilot) Infrastructure Working Group (DISI), two
RFC/FYI documents were identified as output from this working
group. Ruth, along with Russ Wright of LBL, will co-author one

Westine [Page 27]

Internet Monthly Report March 1991

of these, a catalogue of X.500 implementations. Work has begun
to develop the survey form that will be used to gather
information on the implementations. The survey itself will be
initiated in early April.

NORTH AMERICAN DIRECTORY FORUM
-------------------------------

The North American Directory Forum (NADF) is a collection of
organizations which offer, or plan to offer, public Directory
services in North America, based on the CCITT X.500
Recommendations.

The NADF met in Reston, VA the week of March 18-22, 1991. Outputs
from this meeting include NADF-123, "A Naming Scheme for c=US",
which the NADF is widely circulating for comment prior to their
next meeting in mid-July. An ASCII version of NADF-123 has been
published as RFC-1218.

The NADF-123 document proposes the use of existing civil
infrastructure for naming objects under c=US. This has the
advantage of using existing registration authorities and not
establishing any new ones (the document simply maps names assigned
by existing authorities into different portions of the c=US DIT).
The NADF-123 document is intended as the basis for X.500 names in
the US for the long-term; it is important that interested parties
get a copy, review it, and return comments.

A second output, which is still undergoing development, is NADF-
128, a preliminary draft on "Mapping the DIT onto Multiple ADDMDs".
This describes how the c=US portion of the DIT is mapped onto DSAs
and what service-providers must minimally share in order to achieve
a working public directory. The next revision of this document
will likely be ASCII-ized and published as an informational RFC.

PARADISE
--------

This is the first report from the PARADISE project based at the
Department of Computer Science, University College London (UCL).

PARADISE is a sub-project of the broader COSINE project sponsored
under the umbrella of EUREKA by eighteen participating countries

Westine [Page 28]

Internet Monthly Report March 1991

and aimed at promoting OSI to the academic, industrial and
governmental research and development organisations in Europe. The
countries involved are those of the EC, EFTA plus Yugoslavia; that
is: Austria, Belgium, Denamark, Finland, France, Germany, Greece,
Holland, Ireland, Italy, Luxembourg, Norway, Portugal, Spain,
Sweden, Switzerland, United Kingdom, and Yugoslavia.

The partners funded by PARADISE besides UCL are:

- the Networks Group at the University of London Computer
Centre (ULCC), which is a service-oriented organisation
providing a range of facilities to the academic community in
London and the entry point into the UK for IXI, the COSINE
international X.25 backbone;
- X-Tel Services Ltd, a software company based in Nottingham
which currently provides service support to the UK Academic
X.500 pilot; and
- PTT Telematic Systems from the Netherlands, which in turn
has subcontracted the Swiss and Finnish PTTs, and whose
involvement is to create a forum for discussion on X.500
among the European carrier administrations.

The project also aims to have representation from all the
participating countries, which in the majority of cases are the
existing X.500 national pilots.

Of the 18 countries involved, 12 are registered in the tree,
including Ireland and Italy whose nodes were taken up this month.
Most countries are using the QUIPU implementation developed at UCL.
However, a French group have developed PIZARRO, which will form the
basis of the emerging French pilot and, in Italy, a Torino-based
company Systems Wizards are using DirWiz, which is curently the
sole representative from Italy in the tree.

PARADISE recently announced an operational service providing a
central configuration DSA with connectivity via IPSS, IXI, JANET
(UK Joint Academic Network) and the Internet. This DSA contains
the "root of the world" node and provides the glue at the top of
the international DIT. By this summer a central DUA will be
installed with public access via ULCC. Multilingual versions of
this interface will be made available later in the project. Both
these central services will be provided by ULCC, which will be
offering a help desk with telephone and e-mail support.

PSI WHITE PAGES PILOT PROJECT
-----------------------------

As of 91-03-27: There are 74 sites under c=US, 66 operating as
PRDMDs. New additions this month: Sun Microsystems Incorporated
Steve Kille's quality-of-service object classes and attributes
(defined in draft-ietf-osids-qos-00.txt) were implemented.

The attributes and object classes defined in NADF-123 (RFC-1218)
were implemented.

Based on NADF-123 and Kille's draft-ietf-osids-dsanaming-00.txt, an
initial draft of a transition scheme for the c=US DIT is being
drafted. Pilot participants were informed about the upcoming
transition, and will receive the next version of the transition
scheme, which is nearly complete.
