GLIF 2017 World Map created by NCSA/UIUC and EVL/UIC

GLIF 2017 World Map created by NCSA/UIUC and EVL/UIC, with support from GLIF, NCSA/UIUC, UIC, and the State of Illinois.
05 October 2017 – GLIF, the Global Lambda Integrated Facility, announces the availability of new world maps that showcase the global Research & Education multi-gigabit optical network infrastructure owned by its participating organizations. GLIF is a virtual organization (or facility) that consists of network providers, network engineers, computer scientists and computational scientists.
The map features 60 participating networks representing 34 countries and multi-country organizations. GLIF itself owns no resources, so relies on its participants – from National Research & Education Networks, consortia, institutions and individual research initiatives – to share network resources, information and knowledge. In turn, this provides multidisciplinary research teams with shared cyberinfrastructure on which to cooperatively and collaboratively develop, test and implement new optical networking technologies, middleware and applications of global importance.
GLIF organizations that provide bandwidth have capacity in excess of what is required for production usage, which they make available to global research teams, pending availability. These optical networks interconnect and interoperate at GLIF Open Lightpath Exchanges (GOLEs) and Open Exchanges (OXs), creating a global advanced networking fabric that dynamically connects computing, storage, visualization, and instrumentation facilities at collaborating sites around the globe. Note: The GLIF map does not show international capacity dedicated to production usage.
The GLIF 2017 Map visualization was created by Robert Patterson of the Advanced Visualization Laboratory (AVL) at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC), using an Earth image provided by NASA with texture retouching by Jeff Carpenter, NCSA. Data was compiled by Maxine D. Brown of the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC). Support was provided by GLIF, NCSA/UIUC, UIC, and the State of Illinois.

15th Annual Global LambaGrid Workshop

Taking a Bohemian view on R&E networking
18 October 2015 -- The 15th Annual Global LambaGrid Workshop was held on 28-30 September 2015 at the Hotel International, Prague, Czech Republic. More than 110 participants from around the world came to discuss the visions for future research and education networking, whilst also honouring the 20th anniversary of the founding of the host organisation CESNET, the Czech National Research and Education Network. The event was sponsored by Ciena, Cisco and Juniper (Gold Sponsors), ComSource and ICS Intercom Systems (Bronze Sponsors), with support also provided by České Radiokomunikace.
After the opening welcome from Jan Gruntorad, Director of CESNET, the keynote was provided by Erik-Jan Bos of NORDUnet who discussed interconnecting research and education networks to facilitate ubiquitous guaranteed bandwidth and best efforts services on a global scale. This include a vision for intercontinental networking architecture building on existing initiatives such as ANA-200G and AmLight based around open exchange points. Jiri Navratil then discussed some practical example of how the GLIF initiative had enabled CESNET to develop very high bandwidth video hardware and utilise that technology in nearly 20 countries round the world. He stressed the importance of experimental networks that could enable applications that could not be supported by existing production networks.
The opening plenary session then heard about other developments in the GLIF community, including from David Wilde (AARnet) who presented on how GLIF was being used in conjunction with SDN and the Openstack Cloud computing platform to support Australian research; and from Jiri Melnikov (CESNET) on the issues of using latency critical applications over long distances. Cees de Laat (University of Amsterdam) then presented the Pacific Research Platform built around interconnected Science DMZs of top research institutes that are designed to create secure enclaves for data-intensive science and high-speed data transport separate from general-purpose network infrastructures.
The following afternoon and morning sessions were devoted to the Technical Working Group. This opened with updates on the new open exchange in Singapore (SLIX), the forthcoming ANA-200G between Europe and North America, the Hawaiki cable between Hawaii, New Zealand and Australia, and the new SDX initiative at Pacific Wave. There were also updates on new deployments in Eastern Europe and the Netherlands.
This was followed by regular meetings of the AutoGOLE, NSI Implementation and Performance Verification Task Forces which are developing the components that support the dynamic provisioning and monitoring of lightpath networks, setting the scene for a discussion the next day on the requirements for Global Open Lightpath Exchange (GOLE) operators and Software Defined Exchanges. The session continued with a more in-depth exploration of the Global Network Architecture topic that was raised during the keynote, considering the requirement for both point-to-point, point to multi-point and overlay services that could reach anywhere in the world, before concluding with a presentation on the RINA architecture (Leonardo Bergesio, i2CAT) which aims to unify networking and distributed computing.
At the end of the first day, several demonstrations were organised at the venue. This included a 4K video of orchestration using SDN driven switching, real-time high-bandwidth data streaming from a remote controlled robotic vehicle, read/write to storage at 100 Gb/s bit rates using control plane signalling to create paths over multiple backbones, and a showcase of international SDXs using extensions to support programmable services over multiple network domains. The ongoing work of the GLIF Automated GOLE pilot that can set-up inter-domain lightpaths on demand was also demonstrated, along with the use of InfiniBand over long distances.
Several meetings had been held the day before the workshop, including the Governance Working Group (chaired by Kees Neggers) that approved the budget for 2016, the hosting proposals for GLIF 2016, and the process for selecting a new GLIF Chair. There were also meetings of the OGF NSI Working Group (chaired by Guy Roberts, GÉANT Association), the GLIF Americas Working Group (chaired by Joe Mambretti, StarLight International/National Communications Exchange), and the GLORIAD project (chaired by Greg Cole, GLORIAD) that is a collaboration of several countries and carriers to bring lightpath infrastructure to scientific users.
The closing plenary session saw presentations on the production SDN infrastructure being operated by AmLight (Jeronimo Bezerra, Florida International University); the experiences of the StarLight Software-Defined Networking Exchange (Joe Mambretti, StarLight International/National Communications Exchange); and on the Named Data Networking project (Ramiro Voicu, Caltech) which is running a testbed that changes traditional network paradigms by facilitating the fetching of data identified by a name from the network. This was followed by a presentation on deploying alien wavelengths between the US and Brazil (Chip Cox, AmLight).
This was followed by a lively panel session on the ‘Acquiring Subsea Spectrum' that was moderated by Erik-Jan Bos (NORDUnet) and featured Chip Cox (AmLight), Dale Finkelson (Internet2), Joe Mambretti (StarLight International/National Communications Exchange), David Wilde (AARNet), Rod Wilson (Ciena) and Charles Yun (REANNZ). This discussed the opportunities and challenges of acquiring and operating trans-oceanic lightpaths, an area of networking that has traditionally not been the purview of research and education networks but is increasingly looking to be a requirement as collaborative research acquires a global scope.
The workshop concluded with a closing address from GLIF Chair Kees Neggers (SURF) who thanked CESNET for hosting the workshop as well as Jan Gruntorad’s longstanding contributions to research and education networking over many years. He also announced that he would be standing down as the GLIF Chair as he had now retired from SURF and he felt the role needed someone who was actively involved in research and education networking forums. His successor still needed to be chosen by the community, but he hoped this would happen by the end of the year.
A motion was passed thanking Kees for leading GLIF since its inception, but also for his contributions to the wider development of the Internet. GLIF will continue though, with next year's 16th Annual Global LambdaGrid Workshop (GLIF 2016) being held on 29-30 September 2016 in Miami, USA, hosted by Internet2 and Florida International University and co-located with Internet2 Technology Exchange 2016.

New World Symphony at CineGrid Brasil 2014

CineGrid Brazil 2014 hosted a bleeding edge demonstration that put together in the same place three musicians from the New World Symphony orchestra and the CineGrid Brasil audience at University of São Paulo (USP). The New World Symphony performed live the soundtrack for and excerpt of fifteen minutes of the 1929 film São Paulo Sinfonia da Metrópole, by Adalberto Kemeny and Rodolpho Rex Lustig ( The performers played live at the New World Symphony in Miami and their image was transmitted in 4K along with a high definition audio system live to the Universidade de São Paulo Medical School Auditorium. The network bandwith that this experiment required something around 10 Gbps and the connectivity between Miami and São Paulo was provided by AMPATH and ANSP. More:

Cinema technologies have scientific applications

October 08, 2014
By Elton Alisson
Agência FAPESP – In late August, a group of Brazilian researchers transmitted a live version of a 15-minute-long 1929 São Paulo silent film, São Paulo, a Metropolitan Symphony, in 4K resolution (with image definition four times better than full HD television) from the main theater of the School of Medicine at the University of São Paulo (FMUSP) in downtown São Paulo to the New World Symphony concert hall in Miami.
Simultaneously, another group of researchers transmitted the same film, projected in the concert hall of the American orchestra, from Miami to São Paulo in real time – but its sound track was being played live by a trio of instrumentalists in surround sound (on 24 audio channels).
Photo: Agência FAPESPThe demonstration, made using a 10,000-km grid of underwater fiber optic cables between São Paulo and Miami and a connection speed of 10 gigabits per second (Gbps) is one of the high-definition image transmission technologies on ultra-fast networks that are the subject of research in the fields of cinema and digital media.
In addition to its use in the entertainment industry, the technology has been applied to various fields of science and in scientific communication and may help solve problems found with the academic and commercial Internet, say researchers who took part in CineGrid Brasil, an international conference held August 28–29, 2014 at the FMUSP theater.
“We believe that high-definition images will replace the 35 mm film used in movies up to now due to its quality and the potential for online real-time transmission,” noted Jane de Almeida, professor and researcher at the Laboratory of Cinematic Arts and Visualization (LabCine) of the Mackenzie Presbyterian University and one of the event coordinators, in comments to Agência FAPESP.
“The purpose of high-definition images is to enable an “expanded” cinema, one that extrapolates the traditional space of conventional movie theaters and allows images in high-resolution to be displayed in real-time in multipurpose spaces, with applications in fields like telemedicine, astronomy and microscopy,” said the researcher.
Laurin Herr, founder of CineGrid, said in a lecture at the event that the entertainment, art and culture, and science and technology sectors are driving digital media and that they all share the same needs. “The three fields need more speed and easier access to the Internet, in addition to better computers and equipment to store, distribute and visualize ever-larger amounts of data,” he said.
Evolution of the technology
According to the expert, initial attempts at digital cinema were made by the Japan Broadcasting Corporation (NHK) in the early 1980s.
In a 1981 conference on television and cinema engineering held in Los Angeles, researchers from the Japanese public radio broadcaster demonstrated an HDTV projector that piqued the interest of filmmakers such as Francis Ford Coppola, director of the Godfather trilogy and many other films. The technology, however, took more than 20 years to be developed by Nippon Telegraph and Telephone, a Japanese telecommunications company, which presented the first 4K digital cinema system to the world in 2001.
Since the early 2000s, however, major studios have begun to test a technology used to capture digital images called 2K, with a resolution of 2,048 x 1,080 pixels, slightly superior to HDTV, which provides images at a definition of 1,920 x 1,080 pixels.
Starting in 2006, studios began using 4K technology, which doubles the horizontal dimension to 4,096 x 2,160 pixels, becoming the second digital image format currently adopted by the industry, along with 2K.
“Today, 4K is not just a theory but one already found in movies, television, videogames, science and medicine,” said Herr.
“The best 4K resolution technology enables larger images with more detail and more immersion. At the movies, this allows the public to become more involved in the film. In the sciences, it allows researchers to better visualize a microorganism or a human organ, for example, at higher definition,” he said.
On August 29, 2014, the event’s final day, there was a live transmission of a cataract surgery conducted at the Opthamology Department of the Federal University of São Paulo (Unifesp) to the FMUSP theater using two 4K cameras attached to a microscope on the 10 Gbps ANSP (Academic Network at São Paulo, a FAPESP program) network.
In addition to showing the procedure in ultra-high resolution, the transmission technology allows more doctors in training to observe the details of the surgery, said Cícero Inácio da Silva, deputy coordinator of the Open University of Brazil (USB) at Unifesp.
“Generally, surgery such as this is observed by, at most, one student or medical resident, through what is known as ‘piggybacking’,” said Silva. “The 4K transmission of the procedure on a high-speed network allows an audience full of doctors in training to watch from an auditorium.”
In December, the researchers plan to transmit another ophthalmological surgery from São Paulo to Miami in 4K resolution, but this time in 3D.
Technological challenges
The goal of the experiments, in addition to demonstrating the viability of transmissions of large volumes of high-definition images to the research community, is to test the efficiency of the optical networks.
In countries such as the United States and Germany, these networks are already at 160 Gbps, equivalent to 160,000 times the average speed of broadband Internet in Brazil, at 2 Gbps. However, it is still difficult to transmit films in real-time due to problems such as delay (signal delay).
“Today, there is a 130-millisecond delay in data transmission via the fiber optic network between São Paulo and Miami, and a half-second delay between São Paulo and Japan,” said Luis Fernandez Lopez, general coordinator of ANSP. “In these two cases, there are physical problems that involve the speed of light in fiber optic cables, which is less than that in the vacuum and cannot be increased.”
The more serious problem in transmitting a 4K film over a high-speed network such as the one that connects São Paulo to Miami is that the film needs to be compressed into data packets of approximately 500 megabits per second – because a single image can have 8 megapixels (millions of pixels) – and decompressed upon arrival at the location where it is to be shown.
According to Lopez, the process of compression and decompression increases the delay and complicates the transmission problem. “If these 4K films could be transmitted without first having to be compressed, there would be less of a delay problem. So digital media professionals would like to have a 10 gigabit-per-second fiber optic network to transmit films in this image format without any transmission problems.”
According to Lopez, this same demand for faster and more efficient networks is shared by researchers in the fields of astronomy and particle physics.
By studying the problems related to quality control of the digital film transmission signal, solutions can be developed to improve the performance of academic networks.
“Assistance in conducting these demonstrations gives us at ANSP a huge advantage because they put us through the paces and prepare us to handle the demands of researchers from the state of São Paulo,” he said.
“When a particle physicist comes to us asking for a 10 gigabit per second link such as for CERN [European Organization for Nuclear Research, in Switzerland, which houses the Large Hadron Collider (LHC)], to perform experiments without any transmission failure or loss of data, we feel confident because we’ve already done it for the CineGrid,” he said.
Research community
This was the second time that the event was held in Brazil. The first was in 2011 in Rio de Janeiro. The event is organized in several countries by the non-profit international association CineGrid.
Established in the United States in 2004, the association was designed to constitute an interdisciplinary community focused on the investigation, development and demonstration of collaborative network tools that enable the production, use, preservation and exchange of ultra-high-quality digital media on high-speed fiber optic networks.
The association was conceived in the early 2000s, when the convergence of digital technology in the film industry began. Today, it boasts 50 members from around the world, including universities, research institutions, film studios, hardware and software developers and academic networks such as the ANSP.
