According to a website of a physicist organization, scientists have recently achieved record-breaking data transmission speeds, helping to open the door to next-generation high-speed data transmission technologies.
At the SuperComputing 2011-SC11 conference held in Seattle, USA in mid-November, an international team of experts achieved a bi-directional speed of 186GB per second over a wide area network. This speed is equivalent to the transmission of 2 million gigabytes of information per day, which is almost equal to the capacity of 100,000 full Blu-ray DVDs.
This team of scientists consists of high-energy physicists, computer experts, and network engineers. Its members are from California Institute of Technology, Victoria University, University of Michigan, European Center for Nuclear Research (CERN), Florida International University and other institutions.
Researchers said that their technology will help people cope with the ever-increasing demand for data transmission. In today's world, there is a vast amount of information being transmitted across the oceans and continents through the global Internet. These technologies will lay the foundation for the next generation to tell data transmission technology. This technology will allow transmission speeds of 40 to 100 Gigabits per second. Such scenarios will no longer be dreams, but will be realized in the coming years.
Professor Harvey Newman, head of the High Energy Physics Group (HEP), said: "Our team has demonstrated how we will handle and transmit huge amounts of data in the future. With such tools in hand, we will be able to To achieve tasks beyond the imagination of others, we will see a clear road map to the future, and even others will feel that they lack information."
Utilizing a 100GB network provided by Canada's Advanced Research Innovation Network (CANARIE) and BCNET, a non-profit IT service organization, the group was able to implement the computational center at Victoria University in British Columbia, Canada and Washington State, Washington, USA. 98GB per second between conference centers. At the same time, in the opposite direction, a transmission speed of 88 GB per second was also achieved, and thus the team achieved bidirectional 186 GB per second transmission, which broke the world record of 119 GB per second transmission speed maintained by the team. This record was created in 2009.
In addition, the team also collaborated with researchers from the University of Florida, the University of California, San Diego, Vanderbilt University, and Brazil and Korea to conduct larger demonstrations in California and other locations in the United States, Brazil and South Korea. Domestic facilities conduct massive data transmission experiments.
Such high-speed data transmission also plays an important role in coping with the massive data generated by large scientific equipment, such as Large Hadron Collider (LHC) equipment. This is a particle collision device operated by the European Nuclear Center. Physicists hope that it will help answer some of the most fundamental questions about matter, space and time. To date, more than 100 PB (equivalent to 4 million Blu-ray DVD) data have been processed in data generated by LHC devices, and scientists have used more than 300 computing and storage centers in laboratories and universities around the world. The computing power to deal with this work. In the future, with the further work of the collider equipment, the data it produces will be expected to increase more than a thousand times.
David Foster, deputy head of the IT department at the European Nuclear Center, said: “Lets scientists from all over the world work on the basis of the data obtained by the LHC. This is our goal because This will connect the brightest minds on our planet and work together to solve the biggest problem in the universe.â€
Randall Sobie, a scientist at the Canadian Institute of Particle Physics and a member of this group, added: “The 100G high-speed transmission demonstrated at the SC11 conference is pushing the limits of the Internet technology and it’s Shows that it is possible to transmit mass high-energy particle collision data in terms of PB in hours or days."
Scientists said that the key to this particle colliding work is to find out new possible clues from a large amount of background “noise†data due to known interparticle interactions. In order to achieve this goal, physicists all over the world must repeatedly visit and sometimes need to download or transmit huge amounts of data. It's like taking hundreds of discs at a time from a storeroom where hundreds of thousands of Blu-ray DVDs are stored. The HEP team hopes that the presentation at the SC11 conference will pave the way for more efficient distribution in the future and better utilization of LHC data.
Newman said: “We share our programs and tools with scientists in various fields to help them better conduct more research work in the field and maximize the benefits of 100G high-speed transmission technology. In particular, we hope that This technology will give physicists, especially young students, an opportunity to participate directly in the era of the next big discovery that will be initiated by the LHC."
