Scientists at the California Institute of Technology (Caltech) and the European Organization for Nuclear Research (CERN) have set a new Internet2 land speed record using the next-generation Internet protocol IPv6. The team sustained a single stream TCP rate of 983 megabits per second for more than one hour between the CERN facility in Geneva and Chicago, a distance of more than 7,000 kilometers. This is equivalent to transferring a full CD in 5.6 seconds.
Caltech computer scientists have developed a new data transfer protocol for the Internet fast enough to download a full-length DVD movie in less than five seconds. The protocol is called FAST, standing for Fast Active queue management Scalable Transmission Control Protocol (TCP). The researchers have achieved a speed of 8,609 megabits per second (Mbps) by using 10 simultaneous flows of data over routed paths, the largest aggregate throughput ever accomplished in such a configuration. More importantly, the FAST protocol sustained this speed using standard packet size, stably over an extended period on shared networks in the presence of background traffic, making it adaptable for deployment on the world’s high-speed production networks.
