From Reuters Telcos Demand Greener Network Equipment
Power consumption and other “green” issues are fast becoming the information technology industry’s biggest challenge, reports In-Stat
one of the thirstiest devices: the LAN switch
LAN switches analyze incoming network traffic, determine the traffic's destination based on the packet's incoming frame, and forward the frame toward its destination
Switch vendors who address energy efficiency earliest have significant opportunities to develop competitive advantage in their respective markets
Top U.S. phone companies are demanding more energy-efficient equipment from their suppliers, as the costs of maintaining networks and data centers rise due to surging Internet traffic and energy prices
AT&T, the largest U.S. phone company, recently boosted the capacity of its backbone, or main Internet pipeline, to 40 Gigabits per second amid growing popularity for movie downloading, video streaming, Web-based voice and video calls, and mobile Web surfing.
Donovan said the company was already eyeing an upgrade to 100G and beyond, and studying the potential impact on power consumption.
"When we sit down with the lab folks and say what happens at 400G, they come back and say, there's so much power consumption that everything melts," AT&T's CTO Donovan said. "We need to fundamentally rethink how routing is done on the Internet. We have to fundamentally reshape it."
