Cisco, of course, has already described the positive impact that Facebook has on its business. Last month, the networker's CFO, Frank Calderoni, explained how the Menlo Park, Calif.-based firm is driving a "tremendous amount" of traffic through networks. "Their success helps both of us," he said. Cisco also sees a big opportunity to sell the ASR 5500 to service providers wrestling with the demands of machine-to-machine technology. This could be, for example, vehicle operators delivering cloud-based information into cars, or healthcare systems linking up to patients' health monitoring systems. "We think this is a tremendous opportunity to go after, not just connecting people, but connecting machines," said Nemani. Cisco shares closed up 0.06% at $16.12 on Tuesday. -- Written by James Rogers in New York. >To follow the writer on Twitter, go to http://twitter.com/jamesjrogers. >To submit a news tip, send an email to: email@example.com.
