Fujitsu reveals data transfer protocol 30 times faster than TCP
Japanese tech giant says UDP-derived tech reduces latency to a sixth of current levels
Customer Success Testimonial: Recovery is Everything
Fujitsu has taken the wraps of a new data transfer protocol which it claims is 30 times faster than TCP and will help speed up mobile web browsing and file downloads and reduce virtual desktop latency.
The new proprietary tech is based on the user datagram protocol (UDP) employed for streaming media. As such, it can distinguish between dropped packets and those which haven’t yet reached their destination, thereby removing the need for unnecessary data retransmission, the firm said.
Also included is control tech designed to ensure UDP transmissions don’t hog too much bandwidth by measuring in real-time how much bandwidth is available and ensuring other TCP comms are not overwhelmed.
The final piece of the announcement is technology which converts TCP traffic into the new proprietary protocol, thus speeding up a range of applications including those used for file transfer, virtual desktop and web browsing.
The new protocol comes as a software add-on to UDP – taking advantage of the high speeds it enables while avoiding problems of packet loss and packets traveling in the wrong direction which often hamper UDP communications, Fujitsu said.
In tests between Japan and the US, the new protocol enabled a 30x improvement in throughput for file transfers compared to TCP and reduced packet delivery latency to 1/6 of previous levels.
Fujitsu expects a wide range of uses for the new data transmission tech including mobile comms, inter-datacentre data transfer and virtual desktops, and said it will be commercialised in fiscal 2013 as a middleware product. ®

Re: Yet another bad research paper
Phil's "articles" are basically copy and pastes of press releases with all of the important details cut out and then no link to the original.
The original press release is here;
http://www.fujitsu.com/global/news/pr/archives/month/2013/20130129-02.html
It specifically states "New protocol improves throughput and latency in low-quality communications environments".
Re: Yet another bad research paper
Ha! Beat me to it by moments.
This could be valuable work so far as mobile data comms is concerned. TCP is notoriously rubbish when the link quality is poor, yet loads of mobile software uses TCP.
I just hope that it does get picked up. Though they state they're looking to commercialise it...
That'll probably mean it won't make it into Linux (who'd pay?). And if it doesn't make it into Linux then web servers won't be using it. And if web servers aren't using it then there's not much point in Apple, MS or RIM licensing it. This could turn out to be a fab bit of technology that everyone needs but no one gets because no one's prepared to pay for it.
Yet another bad research paper
I don't think I've ever seen TCP run at 1/30 efficiency except when selective ACK is off and hardware is failing. Making my ADSL2 or WiMAX connection 30x faster would break the known laws of physics for crappy telcos. I could turn down the ADSL S/N ratio until I'm burning away my all FEC bits and I'd only get 1.2x throughput. Maybe they mean that their protocol has 1/30 the latency of TCP on a network that's heavily congested with TCP traffic? If they've come up with a super-polite traffic-avoiding network protocol then they can expect people to tune it to be greedy like TCP.
