RESOURCE DISCOVERY AND DIRECTORY SERVICE
----------------------------------------
In prepartion for a meeting we will hold in March, we have been
discussing ideas about supporting resource discovery by building
resource content summaries and distributing/caching these
summaries according to network topology. The goal is to allow
the information to be efficiently searched throughout a wide
area network. At the meeting we will discuss techniques for
distribution and caching, and ways we can explore these ideas in
the context of the various measurement and prototyping efforts
being carried out by the group members.

INTERNET PROJECTS
-----------------
BARRNET
-------
In February, BARRNet connected one new T1 site, upgraded one 9600bps
site to 56kbps and one 56kpbs site to T1, bringing the total connected
membership to 116. Also in February BARRNet deployed cisco beta
release 9.0 on three "core" routers, putting OSPF into limited
operational use on the cisco platform.

BOLT BERANEK AND NEWMAN INC.
----------------------------
Inter-Domain Policy Routing
During the month of February, we completed extensive testing of the
IDPR configuration database software for the "gated" version of IDPR.
We have also been communicating with members of the Internet community
interested in using IDPR, in preparation for getting IDPR
implementations into the Internet. Our objectives in introducing IDPR
to the Internet are:
(1) To satisfy existing needs for policy-based routing in the Internet.
(2) To gain field experience with IDPR in order to determine what must
be improved.
(3) To prepare for a multiple-site Internet demo of IDPR, with real
applications and real networks.
If you are interested in using IDPR, please contact
msteenst@bbn.com.

CERFNET
-------
On Friday, February 28 CERFnet announced a new service offering,
Dial n Cerf USA, which allows 800 number dial-in access to CERFnet
accounts from around the country. Dial n Cerf USA has the same low
installation and monthly costs as CERFnet's other dial-in
offerings, and has a set hourly cost which is the same no matter
what your location in the country.
Cooper [Page 7]
Internet Monthly Report February 1992
CERFnet is using a new Autonomous System number - AS 1740. CERFnet
is now using the T3 backbone for traffic destined for other
networks which are also using the T3. All other traffic remains on
the T1.
During February CERFnet saw the formation of a new department to
serve its users, Network Information Services. New staff members in
this group include Susan Calcari, Director, Network Information
Services, and Dan Matzke, Network Information Consultant.
The first CERFnet User Group meeting was held and approximately 75
users attended from university, research, and commercial
organizations. The purpose of the User Group is to provide a formal
conduit for communication between CERFnet and its users for
planning regional and national Internet services and to facilitate
communication among CERFnet users.

CONCERT
-------
Development is underway on a trouble ticket system to be used by
the CONCERT NOC in reporting and tracking network related problems.
We are trying to incorporate as many of the RFC 1297 features as
possible, and to follow the ticket handoff procedures coming out of
the IETF UCP working group. The system is being developed from
publicly available tools (e.g., it uses the postgres database
management system from Berkeley), with the intention that it will
be made available to other NOCs. A prototype is now being
evaluated at the CONCERT NOC.
CONCERT has upgraded its OSI test machines, with the installation
of ISODE 7.0, PP 6.0, and SunNET 7.0. When combined, these
packages provide full dual-stack (CLNP and RFC-1006) support for
the OSI applications X.400 (e-mail), X.500 (white pages), FTAM
(file transfer) and VT (virtual terminal).
A two day workshop on Wide Area Information Servers (WAIS) was held
at MCNC early in February. It was jointly sponsored by NSF and
CONCERT and was attended by about 75 people from around the
country.
Joe Ragland represented CONCERT at the FARNET meeting in Atlanta.

CSUNET (THE CALIFORNIA STATE UNIVERSITY NETWORK)
-----------------------------------------------
CSUnet now has three campuses using Compressed Video over it's
private T-1 Network (CSUnet). Those campuses are: Sacramento,
Dominguez Hills, and Bakersfield. On January 16, 1992, the Vice
Presidents of Academic Affairs successfully completed a Video
Teleconference between Dominguez Hills and Sacramento using
compressed 384kbs.
This spring, CSUnet begins a pilot test with the Sprint Meeting
Channel. The Chancellor or any CSU campus with a CODEC will be
Cooper [Page 9]
Internet Monthly Report February 1992
able to set up a Video Teleconference to any other CSU campus/site
or directly to locations on the Sprint Meeting Channel.
The significance of the pilot is the potential: 1) in that the
Sprint Meeting Channel will be available for use across the State
of California via CSUnet; and 2) in that CSU campuses and other
CSUnet members if equipped with CODEC could meet with organizations
outside of California.

MULTIMEDIA CONFERENCING
On February 18, the IETF Audio/Video Transport working group met
via a packet audio teleconference that spanned three continents and
16 timezones. At least 24 people participated from 14 different
locations. The packet audio was distributed over an IP multicast
topology spanning 30 network segments. In addition, 5 sites
directly connected to DARTnet also shared packet video via IP
multicast. A second teleconference with some additional sites was
held March 5.
The primary purpose of these teleconferences was to gauge how well
UDP packet audio will work over an IP multicast topology consisting
of DARTnet as a transcontinental US backbone plus multicast tunnels
reaching out to other sites. The results varied depending upon the
paths traversed by the tunnels, but on the whole it worked pretty
well. For large scale use of packet audio and video, it is clear
that resource management will be required in the network to provide
low delay service.
These teleconferences were also in preparation for a packet
"audiocast" of the general sessions at the March IETF meeting in
San Diego. This first audiocast will be a small-scale pilot, but
may be expanded for future IETF meetings if successful.

LOS NETTOS
----------
Walt Prue attended the first CERFnet Users Group meeting.
An agreement with Nrad (NOSC) and CERFnet was reached to do BGP
routing with the NSFNET backbone over the 132.249.16.0 subnet from
Nrad. This will need to evolve as this DMZ net changes as CERFnet
anticipates. We will want to wait until the AGS+ is installed at
Nrad so BGP2 may be used.

MITRE CORPORATION
-----------------
Work on a white paper concerning OSI packet filtering continued.
It will be published to the IETF NOOP working group list in early
March.
Net management tutorials were aided by the introduction of the "Net
Pet" MIB and agent. The audio-based agent (graphics are coming)
runs on a Sparc. Commands can be sent (via SET) to the agent,
causing a change in mood (seen via GET). This simple model
illustrates a MIB-at-a-glance, a feedback loop familiar to all, and
the concepts of both monitoring and control.

NSFNET/ANSNET BACKBONE ENGINEERING
----------------------------------
Summary
=======
The T3 network continues to perform extremely well as it has since
last November. During February, we have cut over a significant
load of traffic from the T1 backbone to the T3 backbone. Midlevel
networks that were cutover to use T3 in February include SURAnet
(at both College Park and Atlanta), NyserNet/PSI, San Diego (SDSC
and CERFNet), and SesquiNet. These are in addition to the other
midlevel & regional networks that have previously been cut over to
use the T3 system. We are coordinating with several other midlevel
networks that we plan to cutover to T3 during the month of March.
The midlevel networks continue to peer with both the T1 and T3
networks, and continue to use the T1 backbone to communicate with
sites that have not yet cut over to the T3 backbone. This
minimizes the load on the T1/T3 interconnect gateways in Ann Arbor,
Houston, and San Diego. The interconnect gateway load has
decreased as we have added load to the T3 system. We are also in
the process of installing a 4th interconnect gateway at Princeton.
The total inbound packet count for the T1 network was
11,253,312,682, up 1.3% from January. 618,694,272 of these packets
entered from the T3 network.
The total inbound packet count for the T3 network was
3,217,861,812, up 71.6% from January. 470,927,893 of these packets
entered from the T1 network. The number of networks announced to
the T3 backbone was 2390 as of February 28, up from 1160 at the end
of January. As of the last day of February, the T3 backbone was
carrying 30% of total traffic.
The combined total inbound packet count for the T1 and T3 networks
(less cross network traffic) was 13,381,552,329, up 10% from
January.
Testing of the new RS/960 T3 interfaces has begun on the T3
Research Network. System and unit testing has been in progress
Cooper [Page 15]
Internet Monthly Report February 1992
since January. Deployment of the new technology will begin in mid-
April, with gradual installation taking place on the nodes at one
POP at a time. More details on the new technology, testing and
rollout plan will be released within the next few weeks.
Performance on the T1 backbone has not been as good. A number of
problems have been observed, and this is where a large part of our
efforts have been focused over the last month. Congestion at NSS 10
has been minimized by cutover of PSI/NyserNet traffic. The "DCD
Waffle" problem has at long last been identified as two separate
problems, and corrections to these problems are partially deployed
with the remaining software updates on the research network in test
phase. The "extra ICMP net unreachable" problem has been corrected
on the T1 backbone. A recurrent PSP crash is still being analyzed
to find a possible RT kernel bug. A routing problem where IS-IS
link state PDUs were being truncated was identified, having
occurred when some regionals began announcing over 2000 networks to
the backbone. A patch to allow up to 2200 networks was made, and a
new routing daemon that compresses the encoding of networks in the
LSPs is now in test phase. Finally, the RCP nodes are experiencing
CPU starvation, as the routing daemon is processing the large and
growing number of routes learned from the regional networks. That
problem is being addressed by a temporary workaround which suffers
a tradeoff for backup capability, the installation of a faster
processor board in some nodes, and some optimizations to the
routing daemon.
T3 Network Status
=================
Performance on the T3 network has been very good. There have been
reports of intermittent packet loss, but this has been isolated to
sources outside of the T3/T1 systems. As we migrate additional
traffic onto the T3 network we are collecting daily reports on peak
traffic load, and any packet discards on all CNSS/ENSS nodes in
order to detect any problems caused by the added load. We are now
measuring daily average sustained loads of about 5Mbps across a
typical CNSS node (all interfaces) with an average packet size of
about 200 bytes.
The T3 backbone continues to be very reliable. There was a
hardware problem on the backbone CNSS machine at Cleveland that
resulted in two outages. We also continue to experience an
occasional black link on CNSS-CNSS links. With the redundancy in
the T3 network, none of these problems have resulted in extended
outages for any end users. There was also a routing software
problem with the flooding of external BGP updates between the IBM
and Cisco routers which we have worked around.
Cooper [Page 16]
Internet Monthly Report February 1992
An SNMP monitoring problem proved to be an interesting case. One
night the NOC staff observed that the monitor (rover) was reporting
all circuits on the T3 backbone being down at once, though it did
not report any nodes themselves as being unreachable. This problem
was traced to a buffer overflow condition in the internal
communication between the snmpd and smux.routed programs. It seems
that the 44th autonomous system was announced to the backbone that
day, that this caused the data structure that was passed between
the two programs to overflow the buffer. This caused an SNMP error
code to be returned to rover, so that it knew the nodes were
responding but could not get any information on interfaces or
circuits of any kind. This situation lasted for several hours and
did not actually disrupt any network activity or affect user
traffic. It was corrected temporarily by disabling the peering
sessions with several internal backbone cisco AS's that were not
being used by any customers, and more permanently by installing a
new version of the rcp_routed and smux.routed programs.
T1->T3 Cutover Status
=====================
Cutover of traffic began in February as part of the plan begun in
December with the "stability period". Following that period, a
number of software enhancements were made to the backbone routers,
and traffic was cut over one regional (autonomous system) at a time
beginning in February. The following schedule shows sites that have
been cut over and indicates a proposed date for new cutovers. The
Merit staff has been working with the folks at each regional to
plan the cutover and routing plan.
Cutovers completed:
Feb 11: Suranet AS 86 College Park
Feb 19: PSI AS 174 Ithaca
SURAnet AS 279 Georgia Tech (Atlanta)
Feb 20: OARnet AS 690 Columbus
Feb 25: Sesquinet AS 280 and 114 Houston

T1 Network Status Summary
=========================
DCD Waffle Problem on T1 Backbone
=================================
This problem was difficult to track down. In short, the problem was
broken down into two parts: 1) short duration DCD outages being
handled incorrectly by the NSS, and 2) T1 interface card freezes
not being reset properly.
--Short Duration DCD Outages
The Cylink ACSUs on the T1 backbone are configured to drop the DCD
signal on the interface to the RT when an alarm condition occurs on
the circuit. The number of allowable alarm conditions per day
varies with circuit mileage and other issues. These alarms are due
to errored seconds or out of frame conditions. If the number of
alarms on a circuit exceeds the threshold for that circuit, MCI is
notified and takes immediate action to resolve the problem. The
original intent on the configuration for DCD transition was that
the routers could produce a network management alarm when a
threshold was exceeded so that the NOC could take action. However
this implementation was flawed. The actual behavior of the router
was that a logical link outage of up to 2-3 minutes could occur
even for a momentary DCD/alarm condition. Further, this interval
was short enough that the NOC would not necessarily notice it since
it would appear on the problem screen for at most one polling
interval (less than 5 minutes), and there is a possibility it would
not appear at all. Thus, the original intent of having the NOC
notice problems on circuits before the users notice so that advance
action could be taken was not valid.
To resolve this, a decision to configure the software to ignore DCD
transitions was made. This is an interim change, until there is a
design and implementation of a new system to detect short duration
circuit alarms. A routing daemon was deployed that ignores signals
from the T1 driver when DCD fluctuates. A further change to the T1
card driver in the kernel is being deployed in Build 280, which
notably protects split-EPSP links from being affected by this
problem. Full deployment of this kernel was completed the last week
of February.
--T1 Interface Freeze Problem
Due to a known microcode problem on the T1 interface card, these
cards go into a frozen condition where no traffic is passed, up to
several times per day. The recovery from this was that a background
Cooper [Page 18]
Internet Monthly Report February 1992
process would detect this condition and reset the card when this
happened. However, after analyzing the script that performs the
reset, it was observed that the reset did not occur for 1-2 minutes
after the freeze condition began. This guaranteed a routing
transition and additional delay before the logical link would be
useful again.
A new version of the reset script (known as "ricd") has been
deployed This version performs additional logging, has a shorter
time to reset, and also definitively identifies which interface has
frozen (ie. local interface or remote end). The logging allows us
to take action to replace a card that has been freezing too many
times.
Also in the process of analyzing this problem, a daily internal
report has been implemented which gives statistics on how many DCD
and interface reset conditions have occurred on each node. This has
been very helpful in tracking problems, and we will continue to use
and enhance this report for generating action items to improve
performance.
Congestion at NSS 10 (Ithaca)
Congestion at NSS10 has been minimized by cutover of PSI/NyserNet
traffic to the T3 system. We also replaced the PSP-10-16 node to
ensure that we were not having any intermittent hardware problems.
T1 Backbone Circuit Outages
We recorded an above average number of T1 circuit outages reported
during February. The increase in outages was largely due to two
unrelated fiber cuts in the MCI network during the week of 2/17.
IS-IS Link State PDU Truncation Problem
Due to the increasing number of networks advertised by the
regionals to the backbone, the interior routing protocol data units
(IS-IS PDUs) which convey this information between nodes, grew to
the point where they exceeded the maximum packet size supported
(25KB). The symptom was that routing announcements were truncated
and reachability information was not consistently conveyed between
T1 backbone nodes.
This was patched quickly by deployment of a new rcp_routed daemon
that allowed a 32KB PDU size. This allows 2200 routes to be carried
rather than 2000, which buys a few weeks time given the growth in
the Internet.
Cooper [Page 19]
Internet Monthly Report February 1992
A longer term solution is now being deployed. A further enhancement
to the rcp_routed includes a two phased change to compress the
encoding of network numbers within the IS-IS PDU. These changes are
being deployed along with performance enhancements to the routing
software to prevent the CPU starvation conditions outlined below.
Routing Control Processor CPU Starvation
The large number of routes carried in the IS-IS packets on the T1
backbone caused another problem, namely CPU starvation when the
routing daemon generates or processes the long PDUs. This situation
is independent of the amount of traffic on the T1 backbone, and
will simply increase as the number of networks announced to the T1
backbone increases. As long as the T1 backbone is being used for
backup purposes for the T3 backbone, the T1 must carry these
routes.
This problem is being addressed in several ways:
1) Temporarily eliminate use of T1/T3 interconnect as backup for T1
sites to reach sites that have cut over to T3. This allows a
reduced set of networks to be announced to the T1 nodes, and gives
the RCPs some breathing room. This is clearly not an acceptable
condition, as it removes the backup capability, but is necessary to
allow several of the more heavily loaded RCPs to run.
2) Install faster processor cards ("EAPC") in the RT nodes. There
are a limited number of these cards available, and they are
currently being deployed in the RCPs and PSPs in which they are
needed. RCP-13-1 at Palo Alto was particularly heavily affected by
these problems.
3) Deploy the new rcp_routed program described above. This version
contains code optimizations which should allow more efficient CPU
utilization.

NSFNET/INFORMATION SERVICES
---------------------------
At the close of February, 1992, 4,775 nets have been configured for
announcement on the NSFNET infrastructures. Of this total, 2,390
nets are configured for T3 announcement, and 1,601 nets are located
outside of the United States. Venezuela and South Africa are the
most recent international connections to the NSFNET. A discussion
of packet traffic for February on the NSFNET, as well as an

NORTHWESTNET
------------
On February 20, 1992 NorthWestNet held the first of three training
sessions for K-12 educators as part of a prototype project co-
sponsored by the University of Washington, a NorthWestNet founding
member. The project involves six schools in Washington and Oregon
states and is designed to encourage use of the Internet in
curriculum development, educational reform, and collaboration among
K-12 teachers.
Close to 50 educators attended the first class, which covered
Internet applications such as email, file transfer, Archie, and
news groups. The class was taught by University of Washington
staff from Central Computing and faculty from the College of
Education.

SAIC
----
SAIC Activities for February
During the month of February, the integration of the IDPR parser
with gated was begun. Removal of the old inter-process
communication mechanisms was scheduled for later, but in order to
allow more complete testing of the modules as they incorporate the
database utilities, it is being resolved first. A new interface to
CMTP has been defined that will simplify packet generation and
significantly reduce the number of memory allocation calls. The
new scheme allows for re-use of most message buffers, and preloads
many of the fields in CMTP headers further reducing copying.
The MIB has been completed, although it requires a few days of
editing before a new submission is made. The solution for the
representation of policies has been to use the OPAQUE object type.
This may generate some controversy, however, the alternatives were
unacceptable.
Chi Chu continued work on NVLAP, although poor connectivity to DCEC
and hardware problems on the development host have caused
considerable difficulties. Ken Carlberg is continuing work on the
prototype that uses multicast extensions to CLNP.
Planned Activities:
Integration and testing of the VGP module. We may be able to
install SNMP management via the SMUX interface in gated. This will
provide both an extra debugging tool and allow experimentation with
the IDPR MIB.

SRI
----
SRI's Network Information System Center (NISC) updated the RFC
Index in response to each RFC issued in February. There were six
RFCs issued in February 1992.
The RFC Index contains citations of all RFCs issued to date in
reverse numeric order. It's also a quick reference to determine if
any RFC has been obsoleted and gives a pointer to the replacement
RFC.
The RFC Index also supplies the equivalent FYI number, if the RFC
was also issued as an FYI document.
Paper copies of all RFCs are available from SRI, either
individually or on a subscription basis (for more information
contact nisc@nisc.sri.com or call 1-415-859-6387). Online copies
are available via FTP from ftp.nisc.sri.com as rfc/rfc####.txt or
rfc/rfc####.ps (#### is the RFC number without leading zeroes).
Additionally, RFCs may be requested through electronic mail from
SRI's automated mail server by sending a message to mail-
server@nisc.sri.com. In the body of the message, indicate the RFC
to be sent, e.g. "send rfcNNNN" where NNNN is the number of the
RFC. For PostScript RFCs, specify the extension, e.g. "send
rfcNNNN.ps". Multiple requests can be sent in a single message by
specifying each request on a separate line. The RFC Index can be
requested by typing "send rfc-index".
The update to the TCP-IP CD-ROM is now available from the NISC.
The update contains all RFCs issued through Feb. 7, 1992. New

On a lesser scale in some senses, but broader in others, UCL took
part in the voice conference with ISI/BBN/DARTNET/OZ/Sweden et al,
as reported elsewhere by Steve Casner. Problems at UCL may have
been partly caused by queueing delay variations for IP packets with

PILOTING AUTHENTICATION AND SECURITY SERVICES WITHIN
OSI APPLICATIONS FOR RTD INFORMATION (PASSWORD)
COLLABORATORS:
University College London (Coordinating Partner)
Cambridge U
DANET
E3X
GMD
INRIA
XTEL
PROJECT SUMMARY
The project will last for 21 months, with the technical development
concentrated into the first 15 months, and the last six months
being for pilots with ever larger numbers of users and sites.
The project will determine the Security Services required in the
Research and Technical Development (RTD) community for the
provision of specific OSI Applications. The services to be
examined will include the following: Authentication Services,
Directory Services, Message Handling Services, and Document
Handling Services. By offering a variety of pilot services to the
user communities, we expect to obtain an understanding of the
requirements related to data access, data integrity, and data
confidentiality for RTD Community information. We aim to
demonstrate that the pilot services we introduce can be implemented
within the research user environment without hampering unduly the
overall openness and usability of the systems, and provide an
assessment of the usability of the provided services.
The project aims to demonstrate that a security architecture can be
identified which allows usage of a common set of security services
for the above applications.
The project aims to introduce pilot cryptographic security services
in some of the sites connected to the European National Research
Networks. These should be able to be incremental additions to
existing services. To ensure a reasonably open set of facilities,
we will provide more than one toolkit of security components to
provide at least the following: RSA Public Key systems, MD4 Hash
Functions, DES symmetric encryption/ decryption for
confidentiality, and certificates based on the above.
Cooper [Page 26]
Internet Monthly Report February 1992
We will provide Authentication Services using X.509, with multiple
implementations of this core technology. The certificates will be
distributed by X.500 directory services. We will provide
implementations of tools to manage a distributed authentication
service using multiple Certification Authorities with different
implementations, and cross-certification. The structure of the
Certification Services will be provided taking due care of
potential scaling issues - thus we will liaise closely with US
activities which are looking at these same problems in the context
of the intoduction of Privacy Enhanced Mail (PEM) in the Internet.
We aim to provide a framework for the organisational and
operational aspects of introducing certain security services within
the European RTD networking infrastructure. We propose to
implement a key distribution scheme, which will be workable for the
proposed user community.
