Researchers from the University of Tokyo and the US managed to improve the record for data transmission protocol TCP. Achieved a speed of 73 gigabits per second (Gbps), which is near the limit of 100 Gbps network channel. Experiments were carried out in 100-gigabit network TransPAC / Pacific Wave in an advanced protocol LFTCP (Long Fat pipe TCP). This upgrade TCP and its software allow to fully exploit the potential of 100-Gigabit networks without changing the essence of the protocol. Moreover LFTCP has an open source code available to all researchers in the world working in this area, said PC Watch. Fujitsu has developed a faster alternative to TCP.
