Known as asynchronous transfer mode systems or ATM, the technology is based on the concept of carrying audio, video and text information efficiently in small units called cells. Hegde also is co-principal investigator on the NSF grant. Other grants are from the Department of Defense and from the computer and communications industries in the United States and other countries. It is estimated that the vast majority of the world's telephone companies will be converted to ATM systems by early next century. Min plans to develop a guideline of ATM switch architectures and conduct analytical studies on their efficiency under different traffic and network conditions.
Communications systems have many different personalities.
The features and how they can work best for an application are what make one system preferred over another. Min has several patents in ATM switching, with several others pending. In addition to ATM switching, Min and Hegde have made major contributions to mobile communications systems, such as cellular phones. Min and Hegde bid successfully against numerous entries worldwide for the technical portion of the South Korean PCS, which is the international standard for mobile communications systems. We use mathematical reasoning to understand the dynamics of large-scale systems.
