Researchers can adjust network infrastructure to boost bandwidth, optimize latency and save power using an experimental technology called OpenFlow. OpenFlow is in the proof-of-concept stage but someday could be used in business networks to engineer traffic, says Nick McKeown, an associate professor of electrical engineering and computer science at Stanford University.

Researchers devised OpenFlow as a way to test out new network protocols on existing networks without disrupting production applications. The only other option is to set up separate infrastructure on which to run experiments, a costly alternative.
