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

Sept. 17, Prague, Czech Republic

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.
