+ - 233 Google wants variable-rate Ethernet->

optikos writes "When it comes to the fill-rate fraction/ratio of digital-domain Ethernet frames in the underlying analog-domain physical medium, a senior network architect at Google wants to have more flexibility regarding the denominator to push a link's typical fill-rate closer to 100%. The current scheme of inter-Ethernet-frame idle capacity as represented by a numerator that is notably smaller than the (currently-standardized fixed-size) denominator in the fill-rate is claimed to be unsuitable when interconnecting data-centers.

The Institute of Electrical and Electronics Engineers Inc. (IEEE) isn't working on a variable-speed Ethernet standard yet, but Google is pushing for one. It was a point of focus for Bikash Koley, Google's principal architect and manager of network architecture, during a panel session on the last day of OFC/NFOEC last week. What he wants is variable-speed Ethernet. So, instead of running a connection at 100 Gbit/s or 400 Gbit/s, which are the two standard choices, he'd like to pick arbitrary speeds. The technology on the optical side is actually ready for what he's asking. Variable-speed transceivers and flexible-grid ROADMs exist. What's missing is on the packet side: a media access control (MAC) layer that's capable of dealing with a variable-bit-rate physical (PHY) layer.

+ - 178 A good advice from the latest multi-millionaire->

Submitted by Taco Cowboy
Taco Cowboy (5327) writes ""The money is there, just waiting for clever new moves," comments Nick D'Aloisio, the 17-year old teenager from London, who just sold his Summly app company to Yahoo, for a cool 30 million dollars

"If you have a good idea, or you think there's a gap in the market, just go out and launch it because there are investors across the world right now looking for companies to invest in," says Mr. D'Aloisio.

He had first dreamt up the mobile software while revising for a history exam two years ago, going on to create a prototype of the app that distils news stories into chunks of text readable on small smartphone screens.

He was inspired, he said, by the frustrating experience of trawling through Google searches and separate websites to find information when revising for the test.

Trimit was an early version of the app, which is powered by an algorithm that automatically boils down articles to about 400 characters. It caught the eye of Horizons Ventures, a venture capital firm owned by Hong Kong billionaire Li Ka-shing, which put in $250,000.

That investment attracted other celebrity backers, among them Hollywood actor Ashton Kutcher, British broadcaster Stephen Fry, artist Ono, the widow of Beatle John Lennon, and News Corp media mogul Murdoch.
