PRIVACY AND SECURITY
--------------------
The PSRG will meet July 7-9 at Cambridge University, UK, the
week prior to the IETF meeting in Amsterdam. The focus of this
meeting will be the evolving Internet Security Architecture
Document. PSRG members have been forwarding completed writing
assignments to Rob Shirey, who is acting as editor for this
document. A draft of the document will be circulated among the
PSRG members in June, in preparation for further editing during
the meeting.
In April the PSRG issued a call for papers for the Internet
Society Symposium on Network and Distributed System Security,
under the direction of the general chairs, Rob Shirey and Russ
Housley. This will be the second symposium organized by the
PSRG on this topic and it will take place 3-4 February 1994,
Catamaran Hotel, San Diego, California, the same venue and
season as the first symposium. The initial symposium attracted
over 150 attendees and the proceedings were sufficiently popular
as to require a second printing run.

INTERNET PROJECTS
-----------------
ANSNET/NSFNET BACKBONE ENGINEERING
----------------------------------
Network Status Summary
======================
The deployment of new AIX 3.2 operating software was nearly completed
in May. Five remaining routers will be upgraded during June. This
software increases the on-card forwarding table capacity to support
12,000 destinations
Planned topology changes to the T3 network will be deployed in June
Internal routing stability measurements improved on the T3 network
over the April measurements.
Backbone Traffic and Routing Statistics
=======================================
The total inbound packet count for the network (measured using SNMP
interface counters) was 29,991,341,011 on T3 ENSS interfaces. The
total packet count into the network including all ENSS serial
interfaces was 33,883,217,693.
As of May 31, the number of networks configured in the Merit Policy
Routing Database was 12272 for the T3 backbone. Of these, 3102 were
never announced to the T3 backbone (e.g. silent nets). The maximum
number of networks announced to the T3 backbone during the month (from
samples collected every 15 minutes) was 8961, up 8.8% from April.
Average announced networks on 5/31 were 8768.
Planned T3 Backbone Topology Changes
====================================
During June '93, we expect to make a few changes to the T3 backbone
circuit topology. These topology changes are designed to improve
circuit route diversity and avoid multiple circuit outages in the
presence of a fiber cut. The circuit changes include:
1. Add a T3 circuit between the Hartford CNSS and the Cleveland
CNSS.
2. Add a T3 circuit between the Cleveland CNSS and the St. Louis
CNSS.
Cooper [Page 9]
Internet Monthly Report May 1993
3. Remove the T3 circuit between the Greensboro CNSS and the
Hartford CNSS.
This will provide improved physical circuit diversity to avoid
multiple circuit failures during a fiber cut. The addition of the
Hartford to North Royalton and hence the North Royalton to St.
Louis T3s will result in three unique east-west T3 paths and
eliminate the possibility of an east-west backbone partition
resulting from two simultaneous circuit failures. The new T3s were
engineered to ensure that no two T3 circuits transit the same
fiber, conduit, or physical path. On-going studies are underway to
segregate all T3 and T1 tail circuits and back-up T1s to the
greatest extent possible in order to provide the maximum disaster
protection through physical diversity.
Rcp_routed Routing Software Changes
===================================
During May one new release of the routing daemon, rcp_routed, was
deployed. The version named "Less Filling" contained numerous
changes. The major enhancement was to reduce memory consumption
and improve locality of memory access when presented with a large
numbers of routes. This addressed paging problems that were
beginning to occur on some ENSS nodes. Release notes are available
in:
ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes
Routing Stability Measured on the T3 Network
============================================
Internal routing stability measurements are made by monitoring
short term IBGP disconnect times (disconnects of five minutes
duration or less). This is designed to be a measure of routing
stability rather than full mesh connectivity. We monitor overall
stability excluding the biweekly configuration windows.
MONTH overall excluding configs
January 99.1% 99.5%
February 99.0% 99.5%
March 97.5% 99.1%
April 96.1% 97.2%
May 97.4% 98.0%
For the first time since January, the T1 link to E206 (CERN -
Geneva, Switzerland) did not top the list of nodes exhibiting
unstable connectivity. During May, E206 was stable 99.82% of the
Cooper [Page 10]
Internet Monthly Report May 1993
time (1:18:50 overall for the month), with just under 40 minutes
outside of the configuration window. This accounted for much of
the improvement.
ENSS145 (Fix-E) suffered from a number of problems with the FDDI
and ethernet adapters. This node experienced 3:54:35 of
instability over the month (99.47%) and 2:17:37 outside the
configuration window (99.68%), which accounted for most of the
instability.
During May, there were a number of problems with intermittent
CNSS-CNSS circuits. Hard down CNSS-CNSS circuits result in lower
measures of instability since these the T3 network maintains
complete alternate routing for these links. There was recurring
problem with a T3 interface adapter on CNSS40 (Cleveland) on May
28, 30, and May 31. The adapter was replaced on June 1.
As a result of the intermittent CNSS-CNSS circuits, 4 routers
reported over 1 hour of instability outside the config window, 33
nodes reported between 30 and 60 minutes, and 36 reported between
15 and 30 minutes. The remaining 52 nodes reported under 15
minutes of instability (about 99.97% stable).
MONTH > 1hr 30-60 min 15-30 min < 15 min
January 1 5 16 60
February 0 1 4 80
March 2 1 7 78
April 4 0 6 39
May 4 33 36 52
Because of the instability that results from failing circuits, work
is in progress to detect packet loss on circuits in real time, and
more quickly switch to internal alternate routes, thereby
minimizing routing instability.
Notable Outages in May '93
============================
E150 (CONCERT) suffered an extended outage due to power problems on
05/02
E137 (Princeton) lost T3 connectivity due to hardware failure on
05/17

Inter-Domain Policy Routing
During the month of May, we have been conducting a pilot
demonstration of IDPR in the Internet and will continue the pilot
into the month of June. We will publish the results in an Internet
draft, planned for release in July.
We have also been working on a multicast version of IDPR. In May,
we simplified the IDPR route generation software (to conform to the
specification), in preparation for adding multicast route
generation. We have not yet modified the path control software to
enable multicast path setup; this we plan to do in June. We expect
to experiment with multicast IDPR (with resource reservation) on
DARTnet later in the summer.
Scaleability
During the past month, we finished implementing the additional
statistic collection capabilities in the flow-level network
simulator. The simulator can now output delay and throughput
information for all network elements, as well as pairwise end-to-
end drop rates and delays. Statistics may be output as either text
or in a more compact binary format.
Work is currently in progress on the network editor component of
the simulator. The simulator is now fully functional, but the
network model must currently be compiled into the code. The editor
will allow the network topology and simulation parameters to be
changed from a graphical user interface.
Cooper [Page 13]
Internet Monthly Report May 1993
In addition to simulator development, we have started testing the
operation of the simulator's routing and delay models.
(See December '92 Internet Monthly Report for more details about
this project and the toolset being developed.)
Real-Time Multicast Communications and Applications
This month, we interfaced the video server to the BBN PICWIN
desktop video conferencing system as a demonstration of another way
to deliver video to the desktop. We have been using the Parallax
board to view video in a window on a workstation. With the PICWIN
interface, a user can view video in a window on a Sun workstation
using software only; no specialized hardware is needed. To the
video server, a workstation running either the PICWIN software or a
workstation equipped with Parallax hardware, is simply another
video destination. The model of video sources and destinations
supported by the video server and applications makes it relatively
easy to add either hardware or software solutions for displaying
video on a workstation. Although the PICWIN system supports a much
lower frame rate than the Parallax board, it is an interesting
demonstration of a software only solution for displaying video on a
workstation.
We also continued work on features of the video applications that
will be used to demonstrate the new network communications features
such as the ones described below.
Our communications efforts this month have focused on the
implementation of the shared streams service, and the resource
coordination object (RCO) mechanisms used to associate resource
reservation information with flow and group identification, and to
propagate this data to routers. Possible applications of shared
streams include real-time data collection from distributed sensors
and efficient multiplexing of related data flows, e.g., floor-
controlled conferencing. RCO's, in addition to being used for
shared streams, could be used to support applications such as
session management and multicast access control.
To participate in a shared flow reservation, the sender emits a
shared flow RCO, identifying the endpoints of the flow, an
identifier for the flow group, and a flowspec (as described in RFC
1363). This type of RCO is "flow-tracking" -- that is, the RCO
propagation mechanism forwards the RCO along the path(s) taken by
the associated data flow. Each network node along the flow's path
keeps a copy of the RCO. If the network node implements support
for shared flows, the bandwidth information in the RCO is extracted
and passed to the resource reservation mechanism in that node.
Cooper [Page 14]
Internet Monthly Report May 1993
When routing changes occur, the RCO propagation mechanism forwards
the RCO along the new route (and may also indicate that copies
along the old route are no longer needed).
Use of RCOs is transparent to the application using shared flows --
a library interface is being created to provide the API for the
shared flow service. This library encapsulates communication with
the RCO system, which operates as a general network service,

CONCERT
-------
The Communications Research Group has finished most of the ground
work for its packet video development project. A local testbed
consisting of several SPARCstation 10's connected through an 8x8
Fore Systems ATM switch (ASX-100) as well as an Ethernet segment
has been set up. Initial tests demonstrated sustained data rates
of close to 18 Mbps from application to application. This testbed
is expected to be used to realize the goals of high quality
multipoint interactive video to the desktop over IP and ATM
networks. It is anticipated that this activity will assume
increasing significance as the recently announced North Carolina
Information Highway begins deployment next year.
The group has completed a software implementation of a H.261 CODEC.
The preliminary implementation can decode full-color SIF (352x240)
video images at about 3 frames per second on a Sparc 10/30. The
encoder ran at about 1 frame per second with a compression ratio of
40 to 1. The implementation is being extended with a hierarchical
coding option and will be used in studying interactions between
CODEC and network operations. In particular, the impact of IP
priority mechanism on the quality and bandwidth requirement of
video coding will be examined.
Cooper [Page 15]
Internet Monthly Report May 1993
Some initial tests have been conducted with the Parallax's XVideo
card that supports frame capture and JPEG
compression/decompression. The results showed that the current
version of hardware and software can support video communication
with full-color frames of 640x480 pixels at about 11 frames per
second, between two Sparc 10/30's at about 1.5Mbps. The
corresponding video image quality was found quite acceptable. A new
version of XVideo software promises full-motion rate (30
frames/second).

JANET
-----
JANET Report: April 1993
The main activity on JANET during April was the commissioning of
the initial 34 Mbit/s IP data network as part of the SuperJANET
Cooper [Page 17]
Internet Monthly Report May 1993
project. This consists of six sites: University College London
(UCL), Imperial College (and onward to the Royal Postgraduate
Medical School (RPMS) at Hammersmith Hospital), Rutherford Appleton
Laboratory (RAL), Manchester University and Edinburgh University.
Cambridge University and University of London Computer Centre
(ULCC) will be added shortly and Glasgow University later in May.
When ULCC is connected the network will also be attached to the
international access points to JANET (the UK/US Fat-pipe, EBONE and
EuropaNET).
The network was built as a ring of 34 Mbit/s lines with a Cisco
AGS+/4 with two HSSI interfaces at each vertex. Following
difficulties in getting the Cisco kit on time (reported in last
month's report), there was a considerable amount of last-minute
moving of routers around the country involved but everything was
ready for the first SuperJANET demonstration on 29 April. The
network performed well at the demonstration, giving the subjective
impression that there was no difference in speed in accessing data
over the wide area than in doing so over the LAN. (Subsequently,
the RPMS reported obtaining a file transfer rate of 960 Kbyte/s to
UCL -- two-hops away -- when setting up their demonstration, with
standard file-transfer software.)
The performance of the network has still to be measured more
coherently, but initial ping tests show that the round-trip times
between routers are as expected -- ie limited by propagation delays
on the fibres involved. (These range from 3-17 ms round-trip
times.) An initial calculation suggests that in most cases any two
points on the network should be within a 64 kbyte TCP window and
hence it should be possible to drive the network to saturation
using a suitable pair of end system TCP/IP implementations.
Extended windows may be needed in some cases, however.
At present the 34 Mbit/s network is being used as a pilot for the
connection of the sites involved -- ie IP traffic between the sites
flows over this network rather than the JIPS (JANET IP Service --
the standard IP network offering on JANET) by default. JIPS
connectivity between the sites remains as a backup, of course.
(This was demonstrated on Friday 30 April when the SuperJANET
connection into UCL was lost and IP connectivity to this site
quickly dropped back to the JIPS.) Depending on the stability of
the network, it is aimed to bring it into service as part of the
JIPS during July 1993.
Meanwhile, the use of the service network remained high. The total
IP traffic switched across JANET in April was approximately 1000
Gigabyte. Of this approximately 180 Gigabyte passed through the
UK/US Fat-pipe, and approximately 112 Gigabyte to and from EBONE.
Cooper [Page 18]
Internet Monthly Report May 1993
The number of hosts attached can be measured, to first order, by
the size of the ac.uk domain. As of end April it contained 57273
distinct hosts in 301 subdomains. (This was an increase of 2935
hosts and represents approximately 89% of the uk domain.)

-------------
In mid-April, the Chronicle of Higher Education and Merit Network,
Inc., launched a free Internet service that provides in-depth news
and information for the worldwide academic community. ACADEME THIS
WEEK includes:
Cooper [Page 20]
Internet Monthly Report May 1993
Summaries of news in the current issue of The Chronicle of
Higher Education.
A weekly calendar of conferences, symposia, workshops, and
other events in academia.
A weekly schedule of Washington, D.C. events of interest to
women and men in academia.
The week's important deadlines for fellowships, grant
applications, exchange programs, and other funding
opportunities.
A listing of hundreds of job openings at colleges,
universities, and other non-profit institutions worldwide.
All postings are searchable by keyword or geographic region.
The Chronicle, published weekly, is one of the most important
sources of professional news for faculty and administrators at
colleges and universities in the United States and abroad. The
Chronicle is the first major newspaper on the Internet to offer
portions of its contents along with extensive listings of job
openings. The job announcements come from The Chronicle's "Bulletin
Board" section--the world's largest marketplace for jobs in
academia.
A new edition of ACADEME THIS WEEK becomes available on the
Internet every Tuesday at noon. At present, only the current issue
of the Chronicle is available online.
ACADEME THIS WEEK may be accessed via the Internet Gopher at
chronicle.merit.edu, port 70
Send e-mail to help@chronicle.merit.edu for more information about
ACADEME THIS WEEK. Merit plans to continue to help organizations
such as The Chronicle deliver information to the worldwide Internet
community. If you would like more information about these services,

New MichNet affiliates include the Ann Arbor EPA office; Lakeland
Library Cooperative, Grand Rapids MI; Detroit Public Schools; and
the Great Lakes St. Lawrence Seaway Telecommunications
Collaborative/Star Schools Project. Merit currently has 9 member
institutions, and 51 affiliates with 81 MichNet attachments at 79
locations.
Cooper [Page 21]
Internet Monthly Report May 1993
MichNet, with several other regionals, has been participating in
the use of CIDR recommendations for the allocation of address space
for its education, research and commercial users. MichNet has been
allocated a block of 1023 class C network numbers to use. Thirteen
of Michigan's fifteen four-year public universities have direct
MichNet attachments. Eight private colleges or universities, five
community colleges and five K-12 schools also have direct
attachments. The supercomputer facilities operated by the U.S.
Environmental Protection Agency in Bay City and by the U.S. Army
Tank and Automotive Command (TACOM) in Warren both have 1.5Mbps
attachments.
Merit has completed work on the MichNet backbone upgrade. The
Grand Rapids node has been moved from Western Michigan University's
Regional Center in Grand Rapids to the facilities of Teledial, Inc.
Two new T1 lines have been homed to the relocated Grand Rapids node
and the WMU Regional Center is linked using a 56Kbps tail circuit.
A new T1 line links Grand Valley State University to the backbone,
and another links Ferris State University through the Applied
Technology Center at Grand Rapids Community College.
The Network Access Server (NAS) evaluation project is part of a
larger project to upgrade user connectivity to MichNet. Dial-in
asynchronous connectivity has been the focus of the NAS evaluation.
Common connection establishment procedures have been determined to
be the principle requirements which must be met by a NAS
participting in the MichNet pool of ports, as well as the ability
to interface with an authentication helper interfacing with several
authentication servers. The IETF Working Group, NASREQ, is
pursuing this goal. Merit has chosen to work with Livingston in
implementing a pilot NAS which supports the MichNet requirements.
The University of Michigan plans the installation of a 30 port
Livingston Portmaster for beta test in early July. The UofM
machine will be used for PPP access only, with public availability
to authenticated users with the completion of successful testing.
Michigan State University is working with Xylogics, another vendor
who has been actively working with NASREQ and interested in
understanding and meeting these requirements.
The Switched Multimegabit Data Service (SMDS) trial, conducted in
conjunction with Ameritech and Michigan Bell, proceeded well and
has been concluded. Evaluation of the service determined it to be
financially inappropriate for MichNet backbone services. SMDS will
be considered for MichNet service at speeds greater than 1.5Mbps
(T1). Merit has begun to use Ameritech's Frame Relay Service
(FRS). Frame Relay is now operational on T1 links between Ann
Arbor, Flint, Oakland University, and Wayne State University. The
Ameritech FRS offering is a Permanent Virtual Circuit (PVC)-based
Cooper [Page 22]
Internet Monthly Report May 1993
service with access speeds between 56Kbps and T1. There is no
mileage sensitive fee component associated with FRS, but a flat
rate charge for whatever speed is used. FRS offers high-bandwidth
connectivity at a lower cost.

MERIT/NSFNET ENGINEERING
------------------------
Major projects for the month of May were the deployment of a
prototype route server at the MAE-East ethernet, implementation of
a program for automated submission of network announcement change
requests, preparation for a meeting of the NSFNET Regional-Techs in
June, continued IDRP development and progress on the Shared Whois
Project.
Route Server Deployment
A SUN ELC was shipped to College Park, MD. The SURAnet staff is
cooperatively assisting in the installation of the machine which is
now being used as a route server running the GateD routing daemon.
It has been configured to operate BGP peer sessions with the
network service provider peers (including the NSFNET ENSS) and the
RIPE route server. The route server is building a table of routes
to destinations learned from those peers. Later it will be
configured to announce routes back to the peers, in a controlled
fashion coordinated with the other providers along with RIPE.
Automated Submission of Routing Requests
The following note was sent to the regional-techs group to announce
a new method of submitting requests for routing.
Authorized Routing Administrators:
During the past months, we've been developing a scalable approach
to the configuration of the NSFNET/ANSnet backbone as part of our
continued effort to provide and maintain accurate routing
information and a high level of service.
To this end, Merit is pleased to announce
- a new NACR (version 7.0), and
- a new service, a NACR server, available via telnetting to
merit.edu for filling out the new NACR.
Cooper [Page 23]
Internet Monthly Report May 1993
WHY ARE WE DOING THIS?
=====================
We need this new NACR and server, and your help in converting to
these, in order to expedite processing of your NACRs through:
- enhancing validation of information _upon entry_ and aid in
correcting it at that time,
- reducing unnecessary mail,
- providing for automatic 'cc'-ing of appropriate ASs,
- allowing for parsing of consistent NACRs,
- and more!
This move is necessary in order to provide you with a reasonable
level of service and to provide Merit with a scalable, less
resource-intensive method of providing the configuration service.
NEW NACR
========
The new NACR is available via anonymous ftp:
nic.merit.edu:nsfnet/announce.networks/template.net
with helpful information in:
nic.merit.edu:nsfnet/announced.networks/template.net.README.
NOTE: Merit will *only* accept v7.0 templates after 1 July 1993.
NEW NACR SERVER
===============
Some of the good points of this service are presented above;
because we expect it to improve the accuracy and turnaround of your
NACRs, we strongly urge you to try out this service, and work with
us to improve it so that you will use it. (Many thanks to Bill
Manning for being our guinea pig!)
