Newbridge trumpets telecom
invention as a breakthrough
Some Are Skeptical: Company has
developed a sort of X-ray for data
transmissions

OTTAWA - Every telecommunications
equipment maker has tried -- and failed
-- to come up with a gadget that tells it
exactly what kind of signal is sent over a
network.

Now, Newbridge Networks Corp. says
it has found the Holy Grail of network
management -- a way to differentiate
between kinds of signals. And it plans to
have telecom switches with the new
feature on the market by March.

Newbridge has not yet told analysts
about its invention. Experts contacted this
week sounded skeptical that such a
solution could be found.

"It sounds like a great idea. But I'm not
sure how you'd practically implement it.
You'd have to have an awfully efficient
little algorithm," said Gurinder Parhar, a
telecommunications analyst at HSBC
Securities Inc. in Toronto.

If the new system is proven to work, it could cement Newbridge's
place as a major supplier of telecommunications equipment to large
telephone and Internet service companies.

"This is really quite a revolution, to be able to pull a packet of data
apart for identification . . . we do it extremely fast and for a stupidly
low amount of money," Terry Matthews, Newbridge chairman and
CEO, told the Financial Post. "I think we have a winner here,
big-time." The company has applied for a patent on its system,
which was perfected just weeks ago.

Identifying different signals is important because it allows a phone
company to assign priorities to signals that can't wait for
transmission during peak periods of data traffic. An e-mail, for
example, can be put into a buffer and delayed a few seconds. A
video-conferencing signal cannot. But there has been no way to tell
which signal is which once it has been translated into digitized bits.

At the heart of the solution is an intricate algorithm that can identify
and mark signals at lightning-fast speed. Once you can identify the
signals, you can assign them priority and charge customers
according to that priority.

"That means a [telecommunications] provider can say that for
e-mail, I'm only going to charge you .001¢ per packet of signals
because it can suffer a bit of a delay in service. But for voice
signals, which can't tolerate a delay, I'm going to charge you 0.1¢
per packet," Mr. Matthews explained.

Kanata, Ont.-based Newbridge is not the only company that has
been working on this kind of product. Every telecommunications
equipment manufacturer has tried to come up with a cheap solution
to network management.

"That's what everyone is working on feverishly right now, to make
sure that on data networks they can guarantee quality of service.
I'm not sure if anyone has got that nut cracked yet, to be able to
charge by the type of data that's going around," said Marcia
Wisniewski, technology analyst at First Associates, a brokerage in
Toronto.

California-based Cisco Systems Inc., for example, has developed a
system called tag switching. "By 'tagging' the first in a flow of data,
subsequent packets of related data are expedited to the final
destination," Cisco explains on its Web site.

Newbridge's algorithm takes that much further, Mr. Matthews says,
by characterizing the content of the signal. "There's nothing on the
market that does what ours does," he said.

Mr. Matthews said the algorithm is a defining moment in network
development; like the sudden discovery that automobiles run better
if their hard rubber tires are replaced with inflated ones.
