FDT
FDT – One of the key advances in this demonstration was Fast Data Transport (FDT; http://monalisa.cern.ch/FDT), a Java application developed by the Caltech team in close collaboration with the Polytehnica Bucharest team. FDT runs on all major platforms and uses the NIO libraries to achieve stable disk reads and writes coordinated with smooth data flow across long-range networks. The FDT application streams a large set of files across an open TCP socket,
