The new technology, which is a proprietary, has been developed through a software-only approach and is based on User Datagram Protocol (UDP) that is used in streaming media. Even though UDP is a stateless protocol, Fujitsu’s technology has been developed such that it can differentiate between dropped packers and those which haven’t managed to reach the intended destination. This differentiation allows for removal of the unnecessary data before retransmission. This forms the first part of the three part technology.
Second part is a control mechanism that measure the available bandwidth in real-time thereby ensuring that the transmission between the sender and the recipient doesn’t take up all the available bandwidth. The control mechanism also ensures that data that is transmitted using this technology doesn’t overwhelm other TCP communications.
The final component of the technology is a mechanism that allows for conversion of existing TCP traffic to the new UDP based protocol thereby speeding up TCP based applications like for web browsing, virtual desktop and file transfers.
Fujitsu notes that even though there are specific hardware accelerators available to speed up communications they are either too expensive to be installed in low-quality communication environments like wireless networks or too bulky to be installed on a mobile device. Having such a technology implemented through software will allow for installations as a middleware enabling companies world wide to resolve latency and speed issues. This technology can be used as a transmission technology for mobile communications, data transfer between data-centers and high-speed applications involving cloud, virtual desktops, etc.
Fujitsu carried out tests between US and Japan and the results were amazing – a 30 times improvement over TCP communications in data transfer throughput and a reduction in packet delivery latency to a sixth of previous levels.
