Back in July 2004, reports of a Chinese IPv9 prompted a bewildered reaction from internet godfather Vint Cerf. 'What could this possibly be about‾ As far as I know, IANA [Internet Assigned Numbers Authority] has not allocated the IPv9 designation to anyone. IPv9 is not an Internet standard. Could you please explain what is intended here‾" he wrote in an email to China's internet leaders.
The idea was dismissed as a "rogue" project with no official backing. But it is back on the table led, now as then by Xie Jianping, the head of the Shanghai Universal Institute of Chemical Technology and more recently in charge of the decimal network standards team in the MII's science and technology department.
The project returned to prominence at a press conference at the unusual location of the Party Central School in Beijing two weeks ago, where Xie announced that the networking technology had been successfully tested by China Netcom and the Ministry of Commerce.
He asserted that the project is all about China wresting control of its own IP networks away from US dominance for which, he claimed, China was paying 500 billion yuan a year.
The system reportedly uses numerical addressing to make China "the only country able to unify domain names, IP addresses and MAC addresses" into a single, metric system, according to Xinhua. Without any explanation, Xinhua said it also made China the only country outside the US "to have root servers and IP address hardware connectivity servers and its own domain name, IP address and MAC address resources".
In an interview with a skeptical Sina reporter, Xie and denied the project was another Hanxin - a reference to a fraudulent state-backed chip project.
"Our IPv9 has gone through testing and assessment," he said adding that he could not give any more detail but would "make public some material at the necessary time."
But the system, or what little is known of it, has plenty of doubters at home. Sina said critics of the system complain that turning domain names and brand names into numerals is a "backwards step" for the net.
The fact that the decimal network appears to asset control over root servers is bound to alarm internet governance bodies around the world.
And whatever else might be said about it, the project is clearly backed by the MII. "IPv9" raises more questions than answers.

In launching the new iPhone at the Worldwide Developers Conference in San Francisco last week, the Apple front man claimed the screen's IPS LCD technology, developed by LG and Hitachi, also offered superior colour resolution and was “quite a bit better” than Super AMOLED overall.
“You can‘t make an OLED display with this type of resolution right now,” Jobs said on stage. “Retina Display is going to set the standard for displays for the next several years. We don’t think anybody’s going to come close.”
But Samsung disagrees, claiming that the difference in the total number of pixels over Super AMOLED's 800 x 480-pixel resolution is all but negligible to the naked eye, and pointed instead to Super AMOLED's emissive lighting and its ability to deliver far better colour and contrast than more traditional backlit screens like the Retina Display.
"The visibility difference is only 3 to 5 per cent. But raising resolution to that level increases battery consumption by 30 percent,” a Samsung spokesperson told the Korean Herald. “Structurally, IPS LCD technology cannot catch up with AMOLED display technology,” .
One of Super AMOLED's chief attractions is the reduced strain on the battery thanks to that lack of backlighting, with Samsung's new Wave smartphone offering double the battery life of the iPhone. In addition, the Samsung screen offers a contrast ratio thought to be around 1,000,000:1, dwarfing the iPhone's figure of just 800:1.
According to Jobs, the iPhone's screen's 326 pixels per inch meant it had a higher resolution than the human eye “The display is your window into the internet, into your apps, into your media, into your software,” he said. “Retina Display is the best window on the planet.”
Its good to see the Mobile Display evolving but not sure if everyone cares about it. There is a good comparison of AMOLED v/s LCD with lots of pictures here, which will give you a good idea. More details here as well.

In what sounds like the plot of a horror movie, a Bulgarian cellphone company has reportedly suspended the number 0888-888-888 after every single person who was assigned to it in the last 10 years died.
A spokesperson for Bulgarian firm MobilTel refused to comment, telling the Telegraphthat they don’t discuss individual numbers. But the newspaper tracked down the phone number’s eerie history and discovered that each owner had met an untimely end.
The first owner was the former MobilTel CEO, Vladimir Grashnov. In 2001, the 48-year-old died of cancer, although some speculated that he was radioactively poisoned by a business rival.
The number was then passed on to Konstantin Dimitrov, a Bulgarian mafia boss and owner of a $775-million drug smuggling empire. He was shot by a lone assassin in 2003 while eating out with a model in the Netherlands. He was 31.
The third and final owner was Konstantin Dishliev, a real-estate-agent-by-day and a drug-lord-by-night, who secretly ran a massive cocaine trafficking ring. In 2005, after police intercepted $200-million of the white stuff on its way in from Columbia, Mr. Dishliev was assassinated outside a restaurant in Bulgaria’s capital city.
After being temporarily suspended during the investigation into Mr. Dishliev’s death, the number is said to have been de-activated for good. Now anyone who calls is greeted with a recorded message saying the phone is “outside network coverage.”
So are the deaths merely coincidence or proof of a cell phone curse?
Whatever the case, MobilTel could stand to profit off the number by selling it to someone in China, where the number eight is considered lucky. In 2003, a Chinese airline paid 2.33-million yuan (US$280,723) for the phone number 8888-8888.

Advanced IP Interconnection of Services
Release 11 Studies
Study on IMS based Peer-to-Peer Content Distribution Services
Objectives of this study item are:
Without technical alternative to using public numbering resources as addresses, and considering the current forecasts and pending applications for numbers made to numbering plan administration agencies, there is a significant risk that some national numbering/dialling plans will run out of numbers in the near future, which would impact not only these M2M services but also the GSM/UMTS service providers in general.
The Objective is to determine an alternative to identify individual devices and route messages between those devices. Requirements for this alternative include:

So it was not at all surprising to hear Xiaodong Zhu, CTO of ZTE European marketing in the LTE World Summit talking about the end to end green networks. Green technology is not only helpful to for the 'green credentials' but it can also help reduce Opex which can help recover any additional investments (if any).
More manufacturers will hopefully follow the lead.
