Networking's Big Names Feel the Heat in Race to Move Data Faster

The Cutting Edge / Focus on Technology

Telecom: Small start-ups have taken the lead in the drive toward devices that will significantly speed the flow of information.

Along the pure glass byways of optical fiber that make up the core of the world's voice and data networks, a traffic jam of huge proportions is building.

Technology is quickly reaching the point where each hair-like strand of glass--within a bundle of dozens to hundreds of strands--will soon be able to carry a trillion bits of information per second, a blazing burst of data that could represent millions of simultaneous phone calls and Internet data packets.

But the junction points of the network--the brains that route the information to its destination--can currently handle only several billion bits of information per second, an adequate speed for now, but a grim benchmark for the future.

"We're in a situation now of running as hard as we can to just stay a little ahead," said Craig Partridge, a chief scientist with BBN Technologies, an information technology research and consulting firm. "The demand for more bandwidth is growing exponentially."

The perpetual threat of data gridlock, which has become critical during the last few years of the Internet explosion, has launched an intense and contentious race to build what is known as the terabit router.

The biggest names in data and telecommunications networking, including Cisco Systems, Lucent Technologies and Nortel Networks, have started their own projects to build the next-generation machine, which will sit at the center of what is known as the core of the Internet.

But the leading edge, as is often the case with high-end technology, has been seized by a small group of start-ups that are focused exclusively on the terabit prize. Avici Systems Inc. of North Billerica, Mass., Nexabit Networks Inc. of Marlborough, Mass., Pluris Inc. of Cupertino and NetCore Systems Inc. of Wilmington, Mass. are considered among the main contenders in the race, according to some analysts.

Juniper Networks and Argon Networks (now part of German telecommunications equipment maker Siemens) are other young companies that are looking at terabit systems, but have focused more on the current market for advanced super-gigabit routers that can handle billions of bits of information per second.

Even with such a small group of companies, the waters are churning with activity. Telecommunications equipment maker Ericsson of Sweden just announced its purchase last month of Torrent Networking Technologies Inc., a company that produces multi-gigabit routers, for $450 million in cash.

Nortel, in an effort to cover all its bases for the future, has taken a stake in both Juniper Networks and Avici Systems, along with pursuing its own research into creating the next-generation router.

Juniper Networks filed documents last month with the Securities and Exchange Commission for an initial public stock offering.

While there are still years to go before such devices reach the mainstream of the public network, the first real-world tests of these devices this year mark the opening of a potential crack in a market that has been completely dominated by a single company--Cisco Systems.

"The requirement to rebuild the core network is an inflection point and it creates the opportunity for companies to stake out new turf," said Joe Skorupa, director of switching and routing research for RHK Inc., an information technology research and consulting firm based in South San Francisco. "This is a chance for someone to shake up the apple cart."

The move toward terabit routers has been driven by a push and pull of forces that have been building over the last half a decade since the advent of the public Internet.

The push side has been driven by the ever-increasing demand for Internet and other data services that has taken off with an exponential trajectory.

The estimated 50 million users of the Internet have pumped the network into an oversized behemoth that just surpassed the telephone system last year in the amount of information it carries.

RHK estimates that the demand for more speed and capacity will increase by five times this year and four times next year. By 2002, the demand will have grown by nearly 200 times.

The pull side of the equation has come from a variety of technological advances that have suddenly allowed for the transmission of huge amounts of data.

In the 1970s, the days of Arpanet--the precursor to the Internet--data was transmitted at what was the then-blazing speed of 56 thousand bits per second. That figure was quickly increased over the copper wires of the telephone networks to millions of bits per second.

But the introduction of optical fiber in the early 1990s began to change the nature of the network. From millions of bits per second, the backbone of the Internet became capable of carrying billions and even trillions of bits per second in the form of light pulses.
