Routers ship Internet traffic from point to point along a network at high speeds.
Ironbridge joins a growing group of start-ups looking to take a bite out of the high-speed router market. Newcomers like Avici Systems, Pluris and Charlotte's Web Networks either have products on the market or have similar technologies in the works.
Internet traffic carriers Qwest Communications International and the United Kingdom's Energis are testing Ironbridge's new router device, a company representative said.
Ironbridge's terabit router allows communications-network companies to provide what it calls "virtual routing," offering dedicated networks without requiring the addition of more physical routers, a company representative said.
Ironbridge has so far received $85 million in investments.
