New protocol GridFTP already started in a department network Energy Sciences Network (ESnet). This high-speed network is used for the transmission of very large volumes from super computers and large calculable knots, processing the considerable arrays of information. Now tests GridFTP pass in the Scientific laboratory of Okridzh, where the most powerful super computer is set IBM RoadRunner, and also in the National scientific superkomp’yuternom center of power researches in California. Between two by these centers through existing
communications developers succeeded to obtain the rate of data in a 200 megabyte in a second.Jan Foster, director of project Globus Alliance, within the framework of which development of protocol is conducted talks that GridFTP specially intended for the transmission of large files in existing
now networks. "Traditional protocols appeared incapable to manage with the growing volume of transferrable information. Before we marked large delays at a transmission or receipt of information, sometimes a network became overloaded and we lost information in general",
– he talks.New protocol is now responsible for communication of data from computers, engaged in a climatic design and nuclear physics. Principle of action GridFTP consists in that he breaks up files to pieces and through the special algorithm passes
them in the concurrency mode, thus the amount of pieces of files and transfer window extent an user can specify yet to the sign-on. Supports protocol and dokachku files.I am in protocol and unusual mode – Secure Copy, through which it is possible it is assured
to get large files on networks, where often there are failures and overloads. This mode is conception "transmission with confirmation", when the new fragment of file is passed in the protected kind and only since uzel-poluchatel’ confirmed
receipt of previous fragment of information, reports CyberSecurity.ru.
