Improved TCP is designed to optimize bandwidth usage
·
More and more users go to the Internet wirelessly, creating pressure on the infrastructure of mobile operators. A research project, which is coordinated by Muriel Medard, a professor at the Research Laboratory of Electronics at MIT, could provide a remedy, Technology Review reported in its online edition: It is designed to optimize the inefficient in some situations Internet TCP (Transmission Control Protocol) and then send up to ten times more data on existing frequencies. New equipment would not be purchased, it is a pure software solution.
Coded TCP sends algebraic equations using the existing infrastructure, which describe the same number of packages. If data is missing, it can be calculated by the receiving device, without having to be requested again, as would be the case with regular TCP. The equations are simple and linear, so that they can be processed by devices such as cell phones, network routers or wireless base stations.
The approach is worthwhile, especially when the connection is already ill or anyway there is a congestion. A panacea it's loud but not Medard. Must also be proven that the successes achieved under laboratory conditions achievable even in large installations.
The method originated in an international process: It is based on work that originated at MIT, the University of Porto, at Harvard University, the California Institute of Technology and the Technical University of Munich. Medard and her team have the technology now licensed to the company founded by MIT and Caltech start-up code-On Technologies, where she is to be commercialized.
