JUNE 26, 2008 -- Comcast Corp. (search for Comcast) says it has successfully completed a 100-Gigabit Ethernet (100GbE) technology test over its existing backbone infrastructure between Philadelphia and McLean, VA using the 100GbE router interface developed for the Cisco (search for Cisco) CRS-1 routing system.
StrataLight Communications (search for StrataLight) has announced that the interface is based on its 100G DWDM optics.
The Cisco CRS-1 100GbE interface uses Comcast's existing optical infrastructure to enable transmission of 100GbE over DWDM networks. The technology is designed to enable carriers to increase bandwidth per wavelength by a factor of 10 and create efficiencies by simplifying routing and operations through the use of statistically multiplexed 100GbE links.
"This demonstration is another important step in the future of 100GbE networking and we're pleased with Cisco's latest advancements," said John Schanz, executive vice president of national engineering and technical operations for Comcast Cable. "Comcast's single converged core IP network already carries more video, voice, and data traffic than any other, and this new achievement will allow us to scale for tomorrow, while continuing to drive capital and operational efficiencies today."
According to Kelly Ahuja, Cisco vice president and general manager of core routing business unit, "By developing a 100GbE interface for the Cisco CRS-1 platform, providers like Comcast can take advantage of economies of scale, flexibility, and increase the quality of service delivery as they move towards 100G IPoDWDM networks."
The two companies say the implementation tested is consistent with the emerging IEEE 802.3ba 100GbE standard and validates the use of 100GbE and IPoDWDM technologies over Comcast's production network, which was the first and is currently the world's largest 40G IPoDWDM network.
