Korea and Barcelona send HDTV over CA*net 4 with User Controlled
Lightpaths

Ottawa - Over the past week researchers at KISTI (with ANF HDTV TF) in Korea
and i2CAT in Barcelona Spain have been carrying out experiments by
transmitting HDTV video over Canada's CA*net 4 network. They have used User
Controlled LightPaths (UCLP) which permits end user control of the traffic
engineering of the IP network route. It also allows direct peering between
Korea's KREONet2 network and Barcelona's i2CAT network over the CA*net 4
network.

The HDTV transmissions were compressed HDSDI at 270Mbps, with the
collaboration of Research Channel. For the first time, HDTV over IP
transmission spanned 3 continents, Europe, North America and Asia. They
clearly demonstrated that Digital Cinema HDTV quality transmission can work
smoothly over such distances. The Korean team at GIST in Gwangju, Korea got
several cultural productions about Gaudi architecture taped in HDTV format
by i2CAT.

The User Controlled LightPaths used software, developed by the
Communications Research Centre in Ottawa and the University of Ottawa, which
has been deployed across the CA*net 4 network. The software developed under
CANARIE's Directed Research program, and later enhanced under collaboration
with the Technical University of Catalonia, and the i2CAT Foundation allows
authorized end users to reconfigure the direction and routing of
lightpaths across an optical network without requiring the signaling or
permission of a central network administrator. Researchers at KREONet2,
KISTI cross connected their UCLP lightpath from Seattle to New York City
where it was cross connected to an MPLS tunnel provided by GEANT, RedIRIS
and CESCA that linked it to another UCLP lightpath configured across i2CAT.
