Internet Monthly Report JUNE 1991
IAB MESSAGE
A. NEW IAB CHAIR-ELECT
The Internet Activities Board is pleased to announce that Lyman
Chapin has agreed to serve as its chairman beginning July 1, 1992.
During the period July 1, 1991 to June 30, 1992, he will serve as
chairman-elect and work with Vint Cerf, who will continue as
chairman.
Chapin is employed at Bolt Beranek and Newman as its chief network
architect. In addition to his duties on the IAB, he is also
chairman of ANSI X3S3.3, and has just been elected chairman of ACM
SIGCOMM for 1991-1993.
B. INTERNET SOCIETY
The phenomenal growth of the Internet, and particularly the
increasing vendor and commercial involvement, have presented new
challenges for the IAB and its task forces. The IAB continues to
explore policies and procedures to manage the Internet and its
evolution during this explosive growth, while maintaining as much
as possible of the traditions which have led to that success:
openness and cooperation within the Internet community.
The incorporation of the Internet Society as a non-profit
professional society will provide a legal framework for the IAB.
The fact that the IAB has no official standing has been both a
strength and a weakness for the Internet endeavor. The desire to
address the weakness without losing the strength is one motivation
for the creation of the Internet Society.
The IAB actively encouraged the formation of the Internet Society,
and hopes that the Internet community will give the society its
full support. Indeed, as soon as signup became possible, all IAB
members paid their dues and became Internet Society members! We
anticipate that the IAB will become an integral part of the
Internet Society, although the means by which this will be effected
are still under study.
Like the IETF, the Internet Society is designed to be primarily a
grass-roots organization, as free as possible from domination by
any single organization or subset of the Internet community. Thus,
votes will be given to members, not to organizations. Your
participation will make it a success.
Westine [Page 3]
Internet Monthly Report JUNE 1991
C. NAMING THINGS
Periodically, someone asks "what are these protocols called?" The
IAB recommends that the term "TCP/IP Protocol Suite" be used for
the set of protocols built on top of IP. "The Internet" is the
international, interconnected set of datagram networks that once
supported only the TCP/IP suite, but is beginning to support the
OSI suite as well.
"I can't define it, but I know it when I see it".
D. INTERNET ARCHITECTURE RETREAT
On June 11-13, 1991, the IAB, IESG, and IRSG held a meeting at the
San Diego Supercomputer Center, devoted to mapping plans for the
future of the Internet architecture. The meeting divided into five
groups, on: Routing and Addressing, Multi-Protocol Internet,
Security, Traffic Control and State, and Advanced Applications.
We think that substantial progress was made, and the results will
be summarized at the coming IETF meeting in Atlanta.

3) Security Area Report (Steve Crocker, TIS)
The security area within the IETF is responsible for development of
security oriented protocols, security review of RFCs, development
Westine [Page 5]
Internet Monthly Report JUNE 1991
of candidate policies, and review of operational security on the
Internet.
Much of the work of the security area is performed in coordination
with working groups in other areas. The Security Area Advisory
Group (SAAG) is a group of security experts which provides both
consulting help to other areas and direct management of working
groups within the security area.
The main bulk of work for the SAAG consists of a set of formal work
items. These work items correspond to three types of activities.
o Working groups within the IETF Security area. These are marked
as "Security."
o Working groups in allied organizations that function as part of
the IETF Security area. These are marked either "PSRG" for the
Privacy and Security Research Group, or "TSIG" for working
groups within the Trusted Systems Interoperability Group.
o Security relevant developments within working groups in areas
other than security. These are marked according to the relevant
area, viz., Applications, Internet Services, Management, OSI,
Operations, Routing, Standards, or User Services.
o Internal SAAG work items. These are topics which do not merit
the creation of a formal working group but which do need some
level of attention. These are assigned to a SAAG member and
followed for one or more SAAG meetings. These are marked as
"SAAG."
The following is the status of each of the currently open work
items.
wi001: (Security) SNMP Security -- Keith McCloghrie and James M.
Galvin
Develop an enhancement to SNMP to support 3 security services:
data origin authentication, data integrity and data
confidentiality.
The Administrative Model document is being coordinated with the
Network Management Area. Three documents --- the Administrative
Model, the Security Protocols, and the MIB --- are available as
internet drafts. Revised documents should be published in July,
prior to the next IETF, in preparation for submission to the
IESG for consideration as Proposed Standards.
Westine [Page 6]
Internet Monthly Report JUNE 1991
wi002: (Routing) Router Requirements -- Phil Almquist
To identify and resolve security issues as needed by the working
group.
Mike St. Johns has completed a second security review of the
draft. He will be meeting with Phil Almquist during the week of
June 3 to finalize the security considerations section.
wi003: (Security) Site Security Policy Handbook -- P. Holbrook and
J. Reynolds
Create a handbook that will help sites develop their own site-
specific policies and procedures to deal with computer security
problems and their prevention.
The comment period closed May 15th. We are in final revision
status right now, and we still expect to have this available as
an internet draft by 6/1.
wi004: (Security) Security Policy -- Richard Pethia
Create a document that can guide the creation of security
policies for Internet sites.
The "Guidelines for the Secure Operation of the Internet" is
available as an internet draft. It has been forwarded to the
IAB for publication as an informational RFC.
wi005: (SAAG) Export of Security Related Implementations -- Vint
Cerf
Prepare an informational document that summarizes the export
control issues. Appropriate points of contact within the
various government agencies will also be included. The document
will focus on US policy, mentioning others where information is
readily available.
Vint Cerf has begun writing a document. It is on hold pending
changes to export rules to East Europe.
wi006: (Security) Common Authentication Technology -- John Linn
Provide security services to a range of IETF protocol callers in
a manner which insulates those callers from the specifics of
underlying cryptographic security mechanisms, enabling modular
separation between protocol and security implementation
activities.
Westine [Page 7]
Internet Monthly Report JUNE 1991
The working group and its charter will be announced on the IETF
list by June 15.
wi007: (SAAG) Password Management -- Jeff Schiller
BOF at St. Louis IETF.
No progress to report.
wi008: (Applications) Telnet Security Services -- Dave Borman
To enhance the TELNET protocol to include security services.
A specification for authentication within TELNET exists. It has
not been discussed within the last month.
wi009: (SAAG) IAB Crypto Committee -- Steve Kent and Steve Crocker
Create a committee to review crypto related algorithm choices in
the Internet; hash algorithms are the first priority.
A number of cryptographers have been contacted. Steve Kent and
Steve Crocker will contact additional people.
wi010: (SAAG) IP Security Option -- Steve Kent
Create an IP security option.
An internet draft was made available. Comments have been
received and Steve Kent is revising the draft.
wi011: (TSIG) Commercial IP Security Option -- Ron Sharp
Define an IP security option that can be used to pass security
information within and between security domains of the
commercial, U.S. civilian and non-U.S. communities.
A charter has been coordinated and filed. It is waiting for
approval. The CIPSO WG is working on a draft specification that
is being reviewed by Mike St. Johns.
wi012: (PSRG) Privacy Enhanced Mail -- Steve Kent
To specify the inclusion of security services in Internet text-
based mail messages.
The successors to RFC 1113, 1115, and the "FORMS" document (not
previously published as an RFC) are available as internet
Westine [Page 8]
Internet Monthly Report JUNE 1991
drafts. The successor to RFC 1114, the key management
infrastructure, should be available as an internet draft in
July, prior to the next IETF meeting. It is being delayed in
order to accommodate a large number of comments, include the
addition of an appendix which specifies the requirements RSADSI
will impose on certification authorities under its jurisdiction.
wi013: (Applications) Network Printing Protocol -- Glenn Trewitt
To support the working group in selecting and integrating
security services.
Following the March IETF meeting, Glenn Trewitt (Network
Printing WG chair) drafted a memo entitled "Adding Security
Mechanisms to PAP", reflecting CAT integration plans. John Linn
reviewed this memo, and it was subsequently distributed to the
NPP WG list. No further actions are currently planned in
advance of the July IETF meeting.
wi014: (TSIG) Trusted Network File System -- Glover
No progress reported.
wi015: (OSI) Directory Services -- Steve Kille
Include the use of strong authentication in the pilot project.
No progress to report.
wi016: (SAAG) Network Database Privacy -- Joyce Reynolds and Steve
Crocker
Steve Crocker and Joyce Reynolds are drafting a proposed
statement.
wi017: (SAAG) CHRONOS -- ??
The SAAG will request a presentation from the working group at
the next IETF as to the scope of their work in preparation for
identifying security issues.
wi018: (Routing) Router Discovery -- Steve Deering
The internet draft document has been reviewed. Although no
security services are included in this specification of the
protocol, the Security Considerations section accurately
describes the security issues. Provision has been included for
later inclusion of security services in the protocol.

====================================================================
IETF PROGRESS REPORT (Jun 01, 1991 to Jul 01, 1991)
Compiled by Phill Gross (IETF Chair)
1) Let me remind everyone that the next IETF meeting will take
place in Atlanta on July 29 - May 1 1991. Complete registration
and logistics information has already been mailed to the IETF
mailing list. A preliminary schedule for working groups meetings
have also been mailed to the IETF list. For copies of this
information (or for any other question about the upcoming meeting),
please mail to ietf-rsvp@nri.reston.va.us. For general information
about the IETF, you can send questions to mdavies@nri.reston.va.us.
There will be some very important activities at the Atlanta
meeting. We will have report from the IAB on their workshop
conducted last month to look at future directions for the Internet
protocols. We will also discuss an IESG planning activity for
future IETF directions. I have asked each IETF Area Director to
develop an "Area Plan" to chart activities in their areas. These
plans are now being compiled into an "IETF Planning Document",
which will be issued as an Internet-Draft for wide comment. It is
this document we will be discussing in conjunction with the IAB
workshop report. It should be an important session. This is an
open technical discussion, and we invite all interested persons to
join us in Atlanta.
2) I am pleased to report that we have several new people
participating on the IESG. Dave Borman (Cray) has joined the IESG
and is forming a new IETF area called Transport Services. This
will essentially be a reincarnation of Craig Partidge's previous
area, which the exception that we will continue to have User
Services as a separate area. Some WGs from both the Applications
and Internet Areas. Dave will have more to report on this at the
Atlanta meeting. I am also pleased to welcome Philip Almquist
aboard as a Co-Area Director of the Internet Area. Noel Chiappa is
the current Internet Area Director. THe Internet Area is one of
the largest in the IETF, and the addition of Philip will provide
some much needed additional support. Finally, I am *very* pleased
to welcome Bernhard Stockman of Nordunet and Susan Estrada
(CERFnet) as Co-Area Directors of the Operational Requirements
Area. I have acted as interim AD for some time now, and I am glad
we will finally see this important area get the full-time attention
it deserves.
Westine [Page 10]
Internet Monthly Report JUNE 1991
We will discussions of how the these areas will be organized and
managed during the open IESG session in Atlanta.

wi002: (Routing) Router Requirements -- Phil Almquist
To identify and resolve security issues as needed by the working
group.
Westine [Page 15]
Internet Monthly Report JUNE 1991
Mike St. Johns has completed a second security review of the
draft. He met with Phil on the 5th of June to finalize the
security considerations section. Phil asked for some revisions
which are currently underway.
wi003: (Security) Site Security Policy Handbook -- P. Holbrook and
J. Reynolds
Create a handbook that will help sites develop their own site-
specific policies and procedures to deal with computer security
problems and their prevention.
The Site Security Policy Handbook was submitted as an Internet
Draft on June 3. The document was title "Security Policy
Handbook". There some discussion of the name of the handbook;
the title will probably be changed slightly to something like
"Site Security Handbook" before the document is released as an
RFC.
We still have a request in for a plenary slot at the Atlanta
IETF. Paul Holbrook has requested a spot early in the week. It
is not clear at this point if the plenary slot will talk about
the SPWG work as or just the SSPHWG.
wi004: (Security) Security Policy -- Richard Pethia
Create a document that can guide the creation of security
policies for Internet sites.
The "Guidelines for the Secure Operation of the Internet" is
available as an internet draft. A number of good comments have
been received. A revised document will be prepared for the
Atlanta IETF.
wi005: (SAAG) Export of Security Related Implementations -- Vint

MULTIMEDIA CONFERENCING
This month the first real teleconference using the ST-II version of
the Voice Terminal (VT) program, the packet audio component of our
conferencing system, was held among five sites on DARTnet. Also
this month we successfully tested packet video over DARTnet between
ISI and BBN.
For networks with limited bandwidth, we have now implemented
sender-selected floor control for packet video conferences.
Normally, video streams from all participants are sent to all other
sites. On receipt, each individual site decides which video
stream(s) to display. In scenarios where n-way traffic would
exceed bandwidth limits, only one site is selected to send video at
a time. A chairperson or moderator is used to decide which site
distributes its video data and which other ones refrain from
sending video output.

Network Security, the second in a series of JvNCnet Symposiums,
took place on Thursday, June 27, 1991 at Princeton University.
Because today's economy is significantly information-driven and
more people have integrated computing and computer networks, such
as Internet, into their daily work, research, and scholarly
efforts, JvNCnet decided to bring together a prominent panel to
discuss a variety of security issues with respect to the Internet
community. Attention was also paid to requirements of making a
network connection secure. In addition, a member of JvNCnet
described JvNCnet's security protocols.
The following individuals, who comprised the panel, detailed these
subjects.
Stephen Crocker, TIS Internet security
Barbara Fraser, CERT CERT's role in Internet security
Ted Ts'o, MIT Kerberos
William Cheswick, AT&T Bell Labs AT&T's secure gateway
Vikas Aggarwal, JvNCnet JvNCnet's security approach
JvNCnet plans to continue sponsoring symposiums that bring to the
forefront issues, advanced technologies and applications for
networking technologies as well as training sessions, introductory
and advanced. It recognizes the need toprovide a diverse
educational program for its members, users, and anyone interested
in networking. For further symposium information, please send
inquiries to "nisc@jvnc.net."
The JvNCnet Regional Meeting followed the symposium on Friday, June
28. Sergio Heker, during his short briefing, happily announced a
100% increase in membership since JvNCnet became part of Princeton
University nine months ago. He also announced the imminent release
of the JvNCnet Network Operations CenterOn-Line (NOCOL) network
monitoring software package to the Internet community without
charge. For more NOCOL details, send email to "nocol-
info@jvnc.net."
Two parallel sessions, which shaped the design of the regional
meeting, fostered and enhanced discourse among members and with
JvNCnet.

Shari Galitzer visited Merit's NOC in Ann Arbor with a group from
DCA.
Forrest Palmer and Kevin Thompson participated in the Army and Air
Force Secure Tactical Data Network Demonstration held at Ft Gordon,
24-28 June 1991.
Forrest demonstrated the capabilities of a commercial SNMP network
management package to monitor routers and host systems on LANs and
radio communication links. We hope to retain some functional
capabilities for demonstrating network management in a strategic-
tactical internetworking environment for our year-end demo.
MITRE developed methods of collecting data at the transport layer
in the network and analyzing it to provide integrated information
on both the user-level performance and the undelying network
conditions. These methodologies and tools were successfully used
during the Integrated Tactical Demonstration Network (ITDN) in
September 1989 (Allison Mankin's IEEE MILCOM paper describes this
work). Kevin executed tests with TCP traffic over tactical links,
yielding measures of access time, round-trip delay, throughput,
burst power, and loss rates. These measurements were folded back
into the experiments planned for Forward Error Correction
techniques.
Allison has taken delivery of her Sparcstation-2's. Her network
performance visualization software is being moved to the Sparc and
X, from the less portable PIXAR platform.
Walt Lazear presented a briefing on router technology to the DCEC
RDT&E Technology Seminar on 20 June.
Walt also participated in testing to bring ESNET into the OSI

-------------------
Total traffic on the NSFNET T1 and T3 infrastructures measured
7,726,207,578 inbound packets. This figure represents all inbound
traffic from the 16 NSFNET end nodes.
NSFNET T1 infrastructure inbound traffic totaled 7,156,101,602
packets during June, 1991. This total includes packet traffic
entering the T1 network from the T3 network. As of June 28th, 2982
networks are announced to the T1 NSFNET; of this total, 989 are
Westine [Page 27]
Internet Monthly Report JUNE 1991
foreign nets.
NSFNET T3 infrastructure inbound traffic totaled 1,612,595,367
packets during June, 1991. This total includes packet traffic
entering the T3 network from the T1 network. Networks announced to
the T3 NSFNET numbered 583 nets at the end of June.
Testing was completed for a second point of interconnection between
the T1 and T3 infrastructures at San Diego during June. This
interconnect will route production traffic as of July 2. T1 and T3
infrastructures are also interconnected at Ann Arbor. Phase 1 of
the T3 NSFNET deployment was accomplished on June 24th as the node
at Argonne began accepting production traffic. Phase 2 of the T3
expansion includes the addition of core nodes and DS3s to support
the planned E-NSSs at the remaining T1 nodes. Core nodes have been
added at Hartford, New York and Greensboro on the east coast; core
nodes in St. Louis, Denver and Seattle will be added in mid-July.
The installation of T3 nodes at the remaining T1 nodes is
tentavitely planned for mid-July through mid-August.

Stephen Cunningham has taken over the position of Network
Coordinator and will be the first line of contact for network
related matters involving the Pittsburgh Supercomputing Center.
This position was previously held by Gregory Dobrich who has moved
on to work with SURAnet.
We have completed testing of our new T3 ENSS and moved it into
production use. The final network design consists of a two tiered
network hierarchy, consisting of a primary production path and a
secondary backup network path. The primary path, the new high
Westine [Page 29]
Internet Monthly Report JUNE 1991
speed network, contains the T3 (45 Mbps) connection to the NSFnet,
an internal FDDI (100 Mpbs) network between the Mellon Institute
and the Westinghouse Machine room and finally, a Low Speed Channel
(100 Mbps) to the Cray. The secondary path, PSC's previous
production path, consists of the T1 (1.5 Mbps) to the NSFnet, two
internal T1 (1.5 Mbps) connections between the Mellon Institute and
the WEC Machine room and an ethernet (10 Mbps) connection to the
Cray.
PSC's new network should benefit all PSC Users. First, the two
tier hierarchy provides PSC with a very robust network with no
single point of failure. Second, users will see a significant drop
in delay when traversing the T3 instead of the T1 backbone. For
example, the average delay across the T3 between PSC and MERIT is
19 msec, while across the T1 it is 60 msec. Users whose sites do
not yet have access to the T3 backbone will also see a drop in
delay due to improved internal connectivity. For example, the
average delay over the old production network was 20 msec while it
is just 4 msec over the new high speed network.

PREPNET
-------
During June, two new hubs became operational. We installed
cisco-based hubs in Harrisburg and in State College.
We also had four organizations join PREPnet. Muhlenberg College

College will be connected to the Harrisburg hub at 9.6Kbps, ICDD
(International Centre for Defraction Data) will be connected to the
terminal server in Philadelphia via a 9.6Kbps leased line, and
Juniata College will be connected to the State College hub at
56Kbps.
PREPnet and the PA Dept. of Education sponsored a K-12 seminar on
June 12th. The purpose of this seminar was to gather together
people working on K-12 projects so they could talk with each other.
We had thirty people attend the seminar. The attendees were very
enthusiastic. We are making plans for future meetings.

SAIC
-----
Recent Activities:
The first step in the gated port has been completed. The IDPR
prototype now runs as a single process. The first cut at making
IDPR a gated task is underway.
During the past month, Ken Carlberg from SAIC and Mark Sleeper from
Sparta prepared a draft MIB for policy terms for IDPR. They have
done some testing of this MIB using the University of Wisc. CMOT
code. An initial version of the full IDPR MIB which includes the
policy term MIB as an appendix has been completed and made
available to the IDPR WG in preparation for the July IETF meeting.
Planned activies:
Completion of initial gated integration is our highest priority.
Additional code cleaning and optimization will take some time
because of the inefficiencies introduced by the old multi-process
implementation. A design of a new common database for all IDPR
modules will be essential as the current implementation has a lot
of per-module redundancy.
We are investigating the possibility of an IDPR demo at the
upcoming IETF.

SRI NIC
-------
Because the supply of Class B numbers is dwindling due to the
growing number of requests for these numbers, the NIC Internet
registry has imposed more stringent requirements for obtaining
these numbers. Organizations that want to obtain large groups of
Class B numbers (five or more) will be required to furnish the
registry with a detailed rationale for their requests, and in some
cases will be asked to accept alternative allocations of Class C
numbers.
The cumulative total of all IP numbers now assigned is 30,146. See
the table below for a breakdown by month. There are now a total of
1,290 Autonomous System numbers (ASNs) assigned. There are
currently a total of 2,298 domains registered. This includes the

UNIVERSITY OF DELAWARE
----------------------
1. Packet-loss rates from campus to the College Park NSFnet NSS
have reached the six-percent level. We are working with SURA
people to resolve this problem.
2. Work continues on constructing SBus interfaces for
SPARCstations and high-speed crossbar switches for our
Highball project. Work also continues on algorithm simulation
and system robustness. Partly due to recent events, we have
become keenly interested in system fault-tolerant principles.
3. A substantial redesign is in progress on network
synchronization for DARTnet. We hope to improve reliable
timekeeping accuracy to the submillisecond regime.
4. We have obtained audio, video and interface gear to support
real-time conferencing. We plan to use this for DARTnet
experiments and general teleconferencing.

------------------------
The OSI-DS documents are now numbered as a document series.
Two documents were released:
OSI-DS 16:
"Schema for NIC Profile information in X.500"
Chris Weider & Mark Knopper
June 1991
Abstract: The authors wish to put put up a readily accessible,
distributed Directory of Network Information Centers, or NICs.
This paper discusses the schema used to hold the NIC Profiles,
as well as the DIT structure necessary for this information.

Internet Monthly Report JUNE 1991
OSI-DS 17:
"Schema for Information Resource Description in X.500"
Chris Weider
May 1991
Abstract: The authors are interested in allowing distributed
access and updating for Information Resource Description
information to users of the Internet. This paper discusses the
schema used to hold the Information Resource Description
information. The new attributes are taken from the US-MARC
fields, and subfields, with the mapping described in the text.
Preparation is underway for the next WG meeting at the IETF in
Atlanta.

FOX -- FIELD OPERATIONAL X.500 PROJECT
--------------------------------------
The FOX project is a DARPA and NSF 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.
ISI
---
ISI organized the July 9 FOX phone conference, which included
participants from all of the FOX contractors. FOX participants
will meet sometime during the Atlanta IETF.
Steve Hotz (hotz@ISI.EDU)
MERIT
-----
Some of the Merit activities related to X.500 and Directories
which took place during June:
o Work on schema definitions for NIC Profiles and Internet
Online Resources, including internet drafts outlining
that work.
o Met with John Clement of Educom about directory of K-12
people and resources. Started schema definitions for
those as well.
Westine [Page 36]
Internet Monthly Report JUNE 1991
o Began work to implement e-mail based query and updating
system for K-12 for Educom. This will be a prototype for
a later production system.
o Received new workstation to use as DSA for FOX project
activities.
Mark Knopper (mak@merit.edu)
PSI
---
A new X.500-based application, "x5ftp", was released for alpha
testing by FOX project partners. "x5ftp" is an X.500-based
application that allows one to search a portion of the Directory
for references to documents. The application then allows the
selective retrieval of documents by anonymous ftp.
"X5ftp" provides a command-shell interface to a complete X.500
DUA that is specially tailored for document retrieval.
A paper which discusses the role of X.500 in information
retrieval was written. This paper, published by PSI as
Technical Report 91-06-25, is available for anonymous ftp from
uu.psi.com [136.161.128.3] in wp/nir.ms (nroff/troff version, ms
macros) wp/ps/nir.ps (Postscript version) and wp/nir.txt (text
version).

SRI
---
We observed that the Northern Swift Fox DSA was core dumping
given an inconsistent collection of circumstances. The problems
were traced to a lack of swap space on the DSA's host. The
system was reconfigured to increase swap space by approximately
25%. No similar problems have been observed.
SRI began an investigation of options for providing a user
interface to support access to the WHOIS information now stored
in X.500. The decision as to a course of action is forthcoming
in a subsequent report.
A low-level investigation of problems with NIST's Custos 0.1.1
continued. Although original suspicions centered around ISODE
version incompatibilities (Custos 0.1.1 was developed with ISODE
6.0 while SRI is running version 6.8), restoring ISODE 6.0 at
Westine [Page 37]
Internet Monthly Report JUNE 1991
SRI and subsequent recompilation of Custos 0.1.1 yielded no
progress. NIST and SRI will continue their investigation,
focusing on possible configuration differences.
Work on the DISI X.500 implementation catalog continued. Ruth
Lang and Russ Wright (LBL) have written a majority of the
supporting sections that will accompany the implementation
descriptions. A draft list of cross-reference keywords has been
selected and applied to the descriptions. A formatted version
of the document (Internet-Draft) will be made available before
the July IETF meeting.

OIW
---
The OSI Implementor's Workshop (OIW) Directory Service SIG met
during June 10-13, 1991. There were about 20 attendees
representing 15 vendors and users. It was a very productive
meeting and the SIG generated the following outputs:
o Access Control and Replication:
The SIG generated draft working agreements on Access Control
and Replication based on PDAMs and CD. For Access Control,
the SIG created a table for error situations and error
actions. For Replication, the SIG generated the DSA
Replication Conformance and Recommended Practice sections.
These agreements are expected to be stable by the end of
1991 when the standards reach DAM and DIS at the end of
October, 1991.
o Distributed Operations:
The SIG generated draft working agreements on Distributed
Operations based on the EWOS profile. These agreements do
not include any extension work being developed in the
standard body.
o APDU size limit:
The SIG agreed to change Result APDU size limit from 32K to
256K in order to align with the EWOS profile. This limit
will only affect DSAs involved in distributed operations.
This modification is expected to affect the Stable Agreements.
Westine [Page 38]
Internet Monthly Report JUNE 1991
o Pragmatic Constraints:
The SIG agreed to change ub-postal-string for the
Postal Address attribute syntax from 30 to 60 characters in
order to accommodate many existing postal addresses. This
change is expected to be made against the Stable Agreements
at the next meeting. The SIG sent liaison letters to inform
this change and to investigate if this change causes any
problems to current Directory user groups.
o Guideline on AE Title Use:
Informative text was generated in order to guide applications
making use of the AE Title field to access application Entity
Objects in the Directory.

PARADISE
--------
The public access "simple-to-use" PARADISE DUA is available for
sampling on one of the project machines; use "telnet 128.86.8.56"
and enter "dua" at the login prompt. Comments welcomed to the list
Paradise INTerfaceS <pints@cs.ucl.ac.uk>.
The PARADISE packaged DSA and DUA should be available later this
month and will be based on ISODE 7.0 which is due for release in
mid-July.
Interoperability tests are proceeding with the French pilot; the
presentation level difficulty has been resolved and the twelve
French organizations represented below c=FR are now visible. The
QUIPU/PIZARRO discussion has some months to run yet. Inquiries
about PIZARRO may be directed to: Paul-Andre Pays
<pays@fr.emse.mars>. Specific questions concerning the
interoperability testing may be directed to: Paradise
inteROPERability <proper@paradise.ulcc.ac.uk>.

PSI DARPA/NNT X.500 Project
---------------------------
Beta testing was performed on ISODE beta-release 6.9. Experimental
versions of existing DSA and DUA software were tested. Testing was
also performed to ensure that version 6.9 is backwards-compatible
Westine [Page 39]
Internet Monthly Report JUNE 1991
with version 6.8.
Effort was expended in the past month to increase the reliability
of operational X.500 service. To this end:
o Watchdog scripts that ensure that processes related to the
provision of X.500 service continue to run were written and
installed. These scripts will be further enhanced in the
future to detect more error conditions that cause denial
of service.
o Some shuffling of DSA functionality among machines was
performed to better distribute the demands placed on various
machines by the X.500 service.
o An enhanced version of the ISODE software was installed on
all machines to fix version skew problems and further enhance
reliability.
o A systematic schedule of monitoring the reliability of all
machines that contribute to X.500 service was begun.
Testing was performed, using some of the data in the "o=Performance
Systems International" subtree, in preparation for alignment with
the COSINE/Internet Naming Architecture.
Final testing of a beta version of a White Pages front-end for
PC/MSDOS that is layered over FTP Inc.'s PC/TCP kernel is almost
completed. Anonymous FTP release of the binary is slated for the
1st week of July.

PSI WHITE PAGES PILOT PROJECT
-----------------------------
As of June 26, 1991, there are 76 organizations participating in
the White Pages in the United States of America.
New organizations added this past month are:
Cornell University
The practice of pruning non-responsive DSAs from the c=US arc has
been temporarily suspended due to a change in people supporting the
White Pages Manager function. Pruning will begin again next month.
