    'The Grid' Could Soon Make the Internet Obsolete


    The Internet could soon be made obsolete. The scientists who pioneered it have now built a lightning-fast replacement capable of downloading entire feature films within seconds.

    At speeds about 10,000 times faster than a typical broadband connection, “the grid” will be able to send the entire Rolling Stones back catalogue from Britain to Japan in less than two seconds.

    The latest spin-off from Cern, the particle physics centre that created the web, the grid could also provide the kind of power needed to transmit holographic images; allow instant online gaming with hundreds of thousands of players; and offer high-definition video telephony for the price of a local call.

    David Britton, professor of physics at Glasgow University and a leading figure in the grid project, believes grid technologies could “revolutionise” society. “With this kind of computing power, future generations will have the ability to collaborate and communicate in ways older people like me cannot even imagine,” he said.

    [an error occurred while processing this directive]
    The power of the grid will become apparent this summer after what scientists at Cern have termed their “red button” day - the switching-on of the Large Hadron Collider (LHC), the new particle accelerator built to probe the origin of the universe. The grid will be activated at the same time to capture the data it generates.

    Cern, based near Geneva, started the grid computing project seven years ago when researchers realised the LHC would generate annual data equivalent to 56m CDs - enough to make a stack 40 miles high.

    This meant that scientists at Cern - where Sir Tim Berners-Lee invented the web in 1989 - would no longer be able to use his creation for fear of causing a global collapse.

    This is because the Internet has evolved by linking together a hotchpotch of cables and routing equipment, much of which was originally designed for telephone calls and therefore lacks the capacity for high-speed data transmission.

    By contrast, the grid has been built with dedicated fibre optic cables and modern routing centres, meaning there are no outdated components to slow the deluge of data. The 55,000 servers already installed are expected to rise to 200,000 within the next two years.

    Professor Tony Doyle, technical director of the grid project, said: “We need so much processing power, there would even be an issue about getting enough electricity to run the computers if they were all at Cern. The only answer was a new network powerful enough to send the data instantly to research centres in other countries.”

    That network, in effect a parallel Internet, is now built, using fibre optic cables that run from Cern to 11 centres in the United States, Canada, the Far East, Europe and around the world.

    One terminates at the Rutherford Appleton laboratory at Harwell in Oxfordshire.

    From each centre, further connections radiate out to a host of other research institutions using existing high-speed academic networks.

    It means Britain alone has 8,000 servers on the grid system – so that any student or academic will theoretically be able to hook up to the grid rather than the internet from this autumn.

    Ian Bird, project leader for Cern’s high-speed computing project, said grid technology could make the internet so fast that people would stop using desktop computers to store information and entrust it all to the internet.

    “It will lead to what’s known as cloud computing, where people keep all their information online and access it from anywhere,” he said.

    Computers on the grid can also transmit data at lightning speed. This will allow researchers facing heavy processing tasks to call on the assistance of thousands of other computers around the world. The aim is to eliminate the dreaded “frozen screen” experienced by internet users who ask their machine to handle too much information.

    The real goal of the grid is, however, to work with the LHC in tracking down nature’s most elusive particle, the Higgs boson. Predicted in theory but never yet found, the Higgs is supposed to be what gives matter mass.

    The LHC has been designed to hunt out this particle - but even at optimum performance it will generate only a few thousand of the particles a year. Analysing the mountain of data will be such a large task that it will keep even the grid’s huge capacity busy for years to come.

    Although the grid itself is unlikely to be directly available to domestic internet users, many telecoms providers and businesses are already introducing its pioneering technologies. One of the most potent is so-called dynamic switching, which creates a dedicated channel for internet users trying to download large volumes of data such as films. In theory this would give a standard desktop computer the ability to download a movie in five seconds rather than the current three hours or so.

    Additionally, the grid is being made available to dozens of other academic researchers including astronomers and molecular biologists.

    It has already been used to help design new drugs against malaria, the mosquito-borne disease that kills 1m people worldwide each year. Researchers used the grid to analyse 140m compounds - a task that would have taken a standard internet-linked PC 420 years.

    “Projects like the grid will bring huge changes in business and society as well as science,” Doyle said.

    “Holographic video conferencing is not that far away. Online gaming could evolve to include many thousands of people, and social networking could become the main way we communicate.

    “The history of the internet shows you cannot predict its real impacts but we know they will be huge.”

    Kuna issue kuhusu TCP/IP yenyewe. Computer sceintist wanasema imepitwa na wakati muda huu ambao agenda kubwa ni information dissemination. Kwa mfano wanasema kwamba mimi na watu wwngine wawili tunavisit the same web page akatika short interval. sasa wanasema kama mimi na request the same information amabayo mwingine ndo ana i access within muda mchache then kungekuwa na uwezo wa kudeliver the same packets kwa mtu mwingine amabaye anazihitaji hapo hapo bila kuanza kwenye application layer. hata zikiwa njiani kwenda kwingine unaweza ukazichulia hapo.

    Hudhani km ume-enable proxy kwenye web browser yako hiki kinafanyika? Km siyo mtu wa kwanza ku-request let's say CNN.com - Breaking News, U.S., World, Weather, Entertainment & Video News, unaweza kuipata kutoka kwenye proxy server,possibly with some very recent updates (if any). Najua haiwezi kuwa direct kutoka kwenye client pc ya mwenzio!

    hiyo issue nitakuwa labda sijailezea vizuri. huyo professor alikuwa anaelezea scenario ya olympic game ambapo kuna a lot of users wana request video clips. sasa ilibidi waweke copy 6000 za the same clip kwenye different locations ili kupunguza traffic ili iweze kuwa accessed by many users through internet. sasa wanasema kwamba hiyo ni failure ya TCP/IP. Sasa wanachofikiria copy ya one packet inaweza kutumwa kwa watu wote waliorequest kwa mara moja. instead ya badala ya kila user kutengenezewa packets zake kila anaporequest. kwa mfano packet ndo ipo kwenye IP layer halafu bado haijaondoka na kuna mtu mwingine possibly anaweza akawa anahiitaji. sasa badala ya kuanza process ya kwenda mpaka kwenye application layer unaweza ukampa copy ya hizo available packets. Jaribu kucheki kwenye Utube for state of the art research kwenye internet. To my understanding proxy ipo kwenye private network, kwa mfano LAN na WAN na na ni kwa ajili ya users wa hiyo network. Vipi situation kwamba users are on different side of the world ambapo kila mmoja anatokea network tofauti na anakuwa ndo wa kwanza kuaccess hiyo site? Sina statistics ya private network kwenye internet. There could be millions of them. Wanasema TCP/IP ilikuwa ni kwa ajili routing ili kuepukana na tatizo lilikuwepo kwenye kwenye kuconnect two nodes. Lakini sasa ishu sio connection issue ni dissemination ya information kwenda kwa watu wengi

    Freelancer, hivi kwenye TCP/IP version 2 hawajawezesha hilo bado?

    Kuhusiana na The Grid, mimi nafikiri maelezo hapo juu ya mwandishi wa hiyo stori ndiyo yanachanganya. The Grid ideology ilikuwepo muda mrefu... kingine ni kule kusema the grid to make internet absolete.... the grid na internet ni kitu kilekile, it's all about networking - iwe kwa ajili ya social, applications, system redundancy, etc. zinazobadilika ni technologies tu zinazo wezesha hii networking.

    unamaaninisha IPV6? sina uhakika. ila hiyo ni presentation niliona watu wa MIT au berkleys walikuwa wanafanya. Grid computing najua ni mambo ya parallel processing kwenye distributed systems? i dont know ina uhusiano gani na kuifanya internet obsollete

    ...yap, title ya hiyo article naona ndiyo imechemsha zaidi. hata maelezo yake yameelekea kwenye examples zaidi ya technolojia yenyewe.

    ...nilimaanisha the whole protocol stack ya TCP/IP kuwa revamped to version 2, na si IPV6 pekee. Hivyo basi katika hiyo version 2 nilitegemea labda packet access control and 'dissemination' was addressed in the same manner as you described above on post #6.
