The High-Speed Networks UVA Lab develops innovative solutions to address the needs of new communications applications in service-provider, datacenter, and campus/corporate networks. With support from the National Science Foundation and the U.S. Department of Energy, Professor Malathi Veeraraghavan and a group of creative graduate students work in close collaboration with external organizations so that their research contributions can have a meaningful impact. Among their contributions:

New advances in optical wavelength division multiplexing device technologies have enabled the emergence of flexible optical switching systems. A major advantage of optical switches over electronic switches is their lower power consumption. In a joint United States-Japan project, High-Speed Networks UVA Lab researchers
have demonstrated the significant power and cost savings feasible by using multiple wavelengths across access networks from large campuses and corporations. The penalty is a small delay, which is incurred by only rare large dataset transfers.

Commonwealth Associate Professor Kamin Whitehouse and his research group are developing new sensing technology to recognize the occupants of a building, locate them, and determine which electrical and water fixtures they are using. They have developed smarter thermostats, lighting controls, and water heaters based on these sensors.

They have also developed new eco-feedback techniques to help people make better decisions about energy usage. Together, these techniques can reduce the energy consumption of a building by over 25 percent. This research is helping to propel the nation towards the national challenge of slashing building energy consumption by 20 percent by 2020, as laid out by the White House’s “Better Buildings Challenge.”
