New Optical Transport Technology for High Performance Digital Media Demonstrated at GLIF Conference in Prague, Czech Republic

September 17, 2007

Czech Republic (Sept. 17, 2007)

Today at the 7th Annual Global LambdaGrid Workshop in Prague, an international research consortium announced a new capability for communication services based on world-wide optical transport of high resolution digital media streams. Demonstrated publicly for the first time at the workshop, this new capability, “optical multicast,” showed how it was possible to stream multiple high performance, high quality digital media streams among multiple sites around the world from three continents simultaneously. At the demonstration, large screens showed diverse media content including cultural events and historic architecture (Barcelona), scientific visualization (Louisiana), Akihabara “Electric Town” (Tokyo), a live MusicGrid lesson and Canadian landscapes (Ottawa), nanotech virtual instrumentation (Chicago), a chess game (North Carolina), and experimental images (Amsterdam).

Many types of digital media applications and services require large scale high resolution multipoint to multipoint streaming. However, current techniques used for large scale streaming of digital media are limited because networks are designed to manage many small flows of information – and not relatively few very large scale streams. Also, standard routing techniques do not provide sufficient support for large numbers of high volume streams.

To address these and related challenges, a research consortium created an international testbed, the High Performance Digital Media Network (HPDMnet). They are using HPDMnet to investigate new methods for streaming digital media, including extremely high resolution media. The types of technologies demonstrated included new integrated methods for discovering resources, signalling for services, managing and controlling streams, receiving streams, transporting streams, and duplicating streams using dynamically allocated lightpaths. Also, these new methods are being developed to allow for the display of multiple media streams at the same time on individual monitors or on large tiled displays.  These new technologies are being integrated within a services oriented design framework that will allow for much more flexible implementations than current communication services. Instead of pre-determining service attributes, this approach allows for customers to select and integrate their own media service attributes. Component technologies showcased in this demonstration include UCLP (User Controlled Lighpaths), HARC (Highly-Available Robust Co-Allocator), and G-Lambda.

The demonstration in Prague was designed to show a work-in-progress not a completed service or product. Further research will be conducted by the consortium on these methods and technologies. Also, additional demonstrations are planned at other events scheduled for later this year.  The research is intended to develop new services capabilities for the Global Lambda Integrated Facility (GLIF), an international advanced communications facility, which is based on Open Lambda Exchanges around the world.

The demonstration includes technologies from organizations around the world, including the Communications Research Centre Canada (CRC), the Center for Computation and Technology (CCT) at Louisiana State University, CANARIE Inc., i2CAT, CESNET, the Global Lambda Integrated Facility (GLIF), Inocybe Technologies, Inc, the International Center for Advanced Internet Research (iCAIR) at Northwestern University, Masaryk University, MCNC, G-lambda, the National Lambda Rail, Nortel, SARA, StarLight, and the University van Amsterdam.
