Olympic computer trivia - OT

For those who might be interested.. an article by David Strom of the computer networking for the Winter Olympics, and how networking has changed over the last few years.

"Olympic networks then and now"

"The Winter Olympics may be a fond memory for many of us who
had an opportunity to see them live, but I wasn't just
looking at the skaters and skiers. Let me tell you about the contrasts
between the recent 2002 games and when I had a chance to visit Calgary in
1988 and interview the IT staffers who worked for both operations.

The Calgary games were a complete IBM solution, and back then
they used Sytek broadband networks and SNA protocols on IBM's
big iron (for the record, they had both a 3090 and a 3081).
IBM assembled its applications from a tool called Cross
System Product, which at its heart worked with dozens of DB2
databases. CSP was picked because back then it was one of the
few tools that IBM could use for rapid prototyping and
deploying of applications. Interestingly, IBM for its results
system incorporated applications that were developed in 1984
for the Yugoslavian games that originally ran in IBM's
mainframe DOS (not MS DOS). The Calgary IT team had to
convert it twice -- first to MVS (another IBM mainframe
system) and second from Serbo-Croatian to English. The
results system had gone through several iterations since
then, including the fiasco at the 1996 Atlanta games.
Notably, for Salt Lake the results system (along with the
other major IT applications) functioned flawlessly.

IBM lost its Olympics work to SchlumbergerSema, who got the
contract for the next several games' IT plans. This week I
had an opportunity to compare what IBM did in 1988 with what
SchlumbergerSema did for Salt Lake. Gone is the CSP-developed
Info88 information system that was used by athletes,
spectators, and others to keep track of who won which event
and other information. The Info2002 system was Java based and
ran on ordinary PCs with web browsers. Instead of broadband
networks, Salt Lake had a Sonet ring with dozens of T-1 lines
connecting to the various venues.

Applications originated for the Barcelona 1992 games were
field tested at various World Cup matches and then modified
further for Salt Lake: these were also mostly Java-based
along with custom built applications in C+ and C#. There are
numerous applications to track transportation and logistics,
accreditations and security badges, and systems that are used
by on-air commentators and press to track participants and
events.

Redundancy is the byword for the Olympics, and even back in
1988 there were four different networks that connected each
venue with the main data center: the SNA network, leased T-
1s, mobile packet radios or fax machines (well, that doesn't
count as much of a network, but it did come into play when
everything else went south). The Salt Lake games weren't any
different: each venue had two different leased T-1s
connecting it to the main Sonet ring, traveling through two
different physical paths. Each server had twins or in some
cases a third backup unit, spread across two different data
centers. "You don't want a lorry or a snow cat to take out
your cables," said Robert Cottam, who was the chief
integrator for SchlumbergerSema and as you can tell, from the UK.

Doing the Olympic IT implementation is a full-time job for
dozens of staffers. In a few weeks, Cottam will travel to
Turin Italy where the 2006 winter games will be held. "It
takes about three to four years to plan an Olympic system,"
he said.

In Calgary, there were 150 PCs and 200 3270 terminals. Most
of the PCs had 3270 adapters (remember Irma?) to connect them
to the IBM mainframes. In Salt Lake, everything was running
TCP/IP. They had 225 NT boxes supplied as part of the Gateway
corporate sponsorship and 145 Sun servers that were purchased
directly, along with thousands of PCs connected as well. The
Calgary IT budget was about US$120 million -- Salt Lake's was
$300 million (which tracks well with inflation, or even a bit
better).

What was the biggest IT problem? You had to really dig deep
here, because everything worked as it was intended and there
was virtually no downtime across the IT infrastructure. "One
of our NT raid disks crashed about an hour before an event,"
said Cottam. "That was fixed in half an hour and we were able
to go live without any problems."

One thing no one had to worry about in 1988 was Internet-
based port scans and other intrusions. The Salt Lake networks
were scanned a number of times, and firewalls and other
security equipment thwarted various break-in attempts.

We have come a long way in the 14 years since I covered
Calgary. Sytek is gone, CSP is a memory for many of us, and
broadband means a DS-3 instead of cable TV connection. But the
one thing we can all be thankful is that the Olympics came off
well, and I congratulate the many professionals and volunteers
who contributed to its success."
