March 08, 2001, 2:38 PM — Avici Systems is delivering on its OC-192 promises.
A couple of weeks ago the company announced availability of the higher-speed OC-192c interface, but the following day came the real news -- Avici had already landed a major customer for its TSR core Internet router. AT&T announced that its running live traffic over its nationwide OC-192 backbone using Avicis router as the cornerstone.
Avicis channelized OC-192 interfaces, which became available in the third quarter of last year, are now carrying live traffic among Boston, Chicago, Los Angeles, New York, St. Louis and San Francisco.
"Its a tier-1 network," says Seth Spalding, director at Epoch Partners. "And thats a big deal. Theyre one of the only carriers actually carrying live OC-192 traffic. They arent using Juniper, and they didnt wait for Cisco to get there. "
According to estimates by Epoch Partners, the deal is worth approximately $5.2 million.
"They are well on their way toward hitting the $9 million in revenue we predicted for the quarter ending in March," Spalding adds.
This announcement came the day after an announcement regarding the availability of OC-192c (concatenated) interfaces. Now the company will offer both channelized and concatenated interfaces.
Whats the difference between channelized and concatenated? Channelized interfaces consist of four separate OC-48 channels each running at 2.5G bit/sec multiplexed together in an OC-192 pipe, while the concatenated version is a solid OC-192 pipe with one channel running at speeds close to 10G bit/sec. Each implementation has its own benefits. The channelized implementation can hook into existing OC-48 gear, while concatenated pipes require special faster gear. On the flip side, concatenated pipes are better for carrying higher bit rates of traffic.
"Right now we are using the channelized OC-192 interfaces," says William Hoffman, a spokesperson for AT&T. "But we plan to also use the concatenated interfaces when they become available in volume. We had a very robust bake-off selection process, and Avici came out on top."
While only the largest of backbone providers are ready for OC-192 interfaces right now, its clear that service providers are looking for a clear growth path, says Pete Chadwick, vice president of marketing for Avici.
"For a certain class of customers, its becoming another checklist item," he says. "Its going to take some time before OC-192 is the predominant backbone speed, but you cant get through the evaluation process without it."
So, where is routing market leader Cisco Systems with its OC-192 development? The company says that its on target to deliver OC-192 interfaces by the end of this quarter.
