When you talk about quality of service, there are two essential aspects, he said. One is resource management. The second is admission control. If there is any traffic congestion in the network, then the network ensures that no new calls are admitted until resources are available. Current networks like the Internet, he said, do not have access control.
Service can become slow or unreliable when too many users try to use it at once.
Other students such as Shailendra Kumar, a computer science and engineering graduate student, work on ways computers can share tasks. In research funded by NASA, the center is working to find ways for the space agency s computers to share tasks, something that could have applications elsewhere. For example, if computers in one campus lab were overburdened and those in another lab were idle, some of the work could be shifted to the idle lab. Bajpai said he was pleased with the day s demonstration. He said that in addition to being approached by students interested in the center, representatives of a local start-up communications company were interested.
