As the 2008 Olympic Games are broadcast around the world, one little known Olympic feat wasn’t performed by any athlete, but by the China’s Next Generation Internet project (CNGI). CNGI launched a cornucopia of fixed and mobile broadband technologies over the new Internet Protocol version 6 (IPv6) to demonstrate China’s technology advancement to the world. With government mandates and subsidies supporting IPv6 transition in China, South Korea, and Japan, as well as skyrocketing Internet use in those regions, the question is will China and the rest of Asia leapfrog America and Europe in advanced communication technologies.As a little history, the use of Internet Protocol version 4 (IPv4) is nearly ubiquitous. However, there are numerous problems with IPv4, as Internet usage grows. IPv4 uses a 32-bit address which limits the number of routable addresses to about 4.2 billion (2^32). With world population at nearly seven billion, Internet ready device proliferation and Internet usage are growing daily; IPv4 is straining to keep up. At current usage rates, the IP pool is estimated to be depleted by mid-2011. With a combination of network address translation (NAT) and port address translation (PAT) tricks, most ISPs, mobile phone companies, corporations, and home networks use NAT/PAT to setup non-routable “private” addresses to extend and share a single external IPv4 address. This has helped extend the life of IPv4; however NAT/PAT complicates network deployments, architectures and configurations. Assuming a blank slate, most architects would choose a more elegant solution. NAT/PAT is a stop-gap measure employed simply due to the limitations of IPv4 and it has several negative side effects. Since the translation process is complex mathematics calculations, the conversion process is processor and memory intensive, which slows a routers primary purpose, routing packets. With translation, routing tables and configuration become more complex and challenging to deploy. Since most NAT deployments are stateful instead of stateless, it reduces network resiliency and increases the probability of a user’s session interruption because if the NAT gateway fails for any reason all state information is lost and the user’s connection must be reset. With more complex routing and translation complications, NAT/PAT has inherent trace and tracking challenges, which complicate security breach identification, tracking and resolution. Lastly, there are applications which use the original IP address itself which causes a mismatch between the original address and the new NAT/PAT address. This often causes the application to fail or get confused. However with all the IPv4 challenges, it has delivered a revolution in communications. But, IPv6 is poised to make an even bigger impact.Why are China and the rest of Asia deploying IPv6? The US has a population of approximately three hundred million (about 5% of world’s population) and has been allocated about 57% of the total IPv4 addresses. Asia has a population of approximately 3.5 billion or 56% of the world population, but it only has 14% of the total IPv4 addresses. China alone has an allocation of only sixty million IP addresses for a population of over 1.4 billion, which is an over subscription per person by a factor of twenty-three. This mismatch in people to IP address ratio has raised eyebrows in Asia and has spurred significant motivation for an IPv6 transition. Over the last decade, Japan, China, and South Korea have made it a national mandate move to IPv6, primarily out of necessity and perhaps as an attempt to leapfrog over other nations.For the 2008 Olympics, China flexes it technological muscle, debuts IPv6 and, perhaps, gains first mover advantage. In an effort to reframe China’s image from the world leader in manufacturing to a center for technological advancement, the 2008 Olympic Games is the largest usage ever of IPv6 broadband and mobile services in history. With Netcom as the official Olympic service provider, all thirty-seven venues, TV broadcast systems and security systems are all connected into the high-speed optical backbone to provide full and simultaneous event coverage. The cornucopia of IPv6 applications and technologies include GSM/EDGE, WiFi/WiMAX, TD-SCDMA, McWILL, high definition TV, VPN, mobile ticketing, video streaming, mobile blogging, mobile TV advertising, leased lines, security and surveillance and broadband access. The security system alone is the culmination of eight years of effort and it supports over one hundred thousand control and sensor units from a central control management system. It is coupled with an integrated building control and management system which controls temperature, lighting, etc. of all the Olympic venues. With IPv6 sensors throughout Beijing, even taxi service and traffic congestion will be monitored and eliminated quickly to enhance the Olympic experience, as well as demonstrate China’s dedication to technology advancement. To round out the Olympic experience, there is a dedicated network to provide high-speed connectivity for organizers, hotels and media with smart card access so there is no wasted time worrying about those pesky usernames and passwords. With the time and effort China has spend making its Olympic debut, it is now the largest repository of hands-on IPv6 knowledge and experience on the planet. The judge’s score is a resounding “10.0”.But, why is it a big deal? With IPv4 addresses in short supply and running out, the writing is on the wall; IPv6 is the future. The above IPv4 NAT/PAT challenges are all resolved with IPv6 deployment. With IPv6, the number of IP addresses expands to 2^128, which is enough IP addresses for every person on earth today to have over five billion trillion addresses apiece (technically ~5×10^28 apiece). This means that every internet ready device from mobile phones to refrigerators will have its own unique identifier. This will eschew in a new era of smart connected devices and to deliver all new IPv6 enabled services and applications. With Quality of Service flow label built into the IPv6 header, different classes of service for different devices and applications will be possible. This means that in the future your children’s World of Warcraft session will not interrupt your work Video Conference, finally. Security and encryption is integral part of IPv6 which increases its overall robustness. The much debated question is what will be the new uses and applications that will be based on IPv6. What is the IPv6 “killer app”? We simply don’t know today. As IPv6 deployment increases, more programmers and engineers will pour over the specifications and develop creative and innovative ways of leveraging the new capabilities contained within the protocol. I believe that we will see a new round of startup companies in the network and application space that are focused on leverage IPv6’s potential to deliver new innovative services and applications.China is in a unique position in that it is starting to build out its infrastructure and does not have a large sunk cost in capital equipment, unlike North America and Europe. So, China can build out its network with newer more advanced technologies more quickly and easily, which offers its engineers and programmers an enormous first mover advantage and opportunity to gain a hands-on understanding of IPv6’s intricacies. In North America, the only real mandate for IPv6 is the U. S. Government. Although the US mandate called for a migration to IPv6, it provided no budget to accomplish the migration. Only the Social Security Administration, the White House, and a couple other Agencies have implemented IPv6; all others are behind. On the whole, the US and Europe haven’t embraced IPv6.With the whole world watching, one of the greatest Olympic feats of all history is China’s IPv6 deployment. With a spectrum of fixed and mobile technologies and applications, CNGI has delivered the Games crowning jewel and solidified China’s position as an emerging technology leader. The big question is will China and the rest of Asia leverage their head start in advanced communications to take the global leadership position. As always, only time will tell.

One sure way to earn cash right away is to sell your old cell phone. Selling your phone is so convenient these days as you can sell them online for a decent resale value depending on the model.I say a decent resale value because these days, phones change model like people change underwear and so the retail prices of cell phones are very dynamic, often times some models have upgraded versions of them by the next quarter.The reason for so many changes is that mobile technology is moving so fast these days. Just a year ago, 3G was the big thing and now 4G applications are working all over. The cell phone has been transforming into multi utility hand held equipment designed to suit all forms of communication. Phones these days can connect to the net via wi-fi or through regular dial up. Software applications for mobile telephones now include updates from social networking sites like twitter and Facebook as well as updates from informational sites such as tmz, cnn and fox news. I am sure that phones in the future will have a common video interphase wherein you can see the person you are talking to. Let’s not forget that these days’ phones are portable cameras and video recorders. And what is the most popular phone today? An offshoot of a media playing device that capture the world and brought the manufacturers back to prominence: The Apple I phone. Even the iPhone has a newer version as well. By the way, I phone tend to have a higher resale value than some of the other phones. Some of the phones that have higher resale values are Nokia, Samsung, Motorola and even Sony.I know that some phones come with lock in plans for certain mobile carriers but there are ways to make such phones an open line. This process you can find online and if not, well just make sure that when you sell the phone, you have to let the buyer know of the lock up arrangement with the carrier and then it’s up to the buyer to fix the problem.As cell phone technology continues to improve, there is no doubt that newer models of cell phones will make it to the market as fast as the technology is introduced. My best advices for you is to be set with certain technologies and give it at least 18 months before you consider buying a new cell phone and sell your cellphone after you receive your new one.

Traditionally with film this is achieved by use of patterned glass or plastic filters, by stretching a fine mesh over the lens, or less controllably, by breathing on the lens.
These methods all work by allowing most of the light entering the lens to pass straight to the film while diffracting a small amount of light to give the desired effect.
Of course this means that the decision to use a soft focus effect must be taken at the time the photograph is taken; with digital manipulation we have the luxury to apply a soft focus interpretation at any time, and to have much greater control than is possible using filtration with film.
This Optical Diffuser provides a minimum of diffusion and is most commonly used in portraiture; however, it can also be used in landscape photography.
The diffuser has very little effect on the sharpness of the image.
It merely diffuses highlights, reducing contrast and can creates a soft halo around the highlights.
It is also ideal for creating a hint of softness or blurred contours.
As such, diffusers can be used to soften a landscape, or soften skin texture in a portrait to hide minor flaws, giving a gentle, flattering effect.
See the pictures below for comparative shots with and without the use of this filter.
