Introduction and background
GÉANT network presence and its interconnection to other world regions
capability to create artistic events
fusing experiences and cultural backgrounds
GÉANT launch event in Stockholm, 1-2 December 2009
Exciting collaboration for a unique performance:
– Two research networks, GÉANT and TEIN3
– Two continents
– Two cultures 9,300 Km apart
joined through a music and dance performance
made possible by advanced connectivity

The collaboration
The performance was the result of extensive collaboration:
Music was performed at the Museum of Modern Art in Stockholm
– connected with optical fibre to SUNET
– captured, digitalized and sent through the network to Kuala
Lumpur Convention Centre.
Music data travelled:
– from Stockholm to Copenhagen on the NORDUnet link
– then to London on the GÉANT network
– then to Singapore on the TEIN3 link
– then to Kuala Lumpur via TEIN3 and MYREN
Dance was performed at the Convention Center in Kuala Lumpur:
– captured, digitalized and sent through the same path in reverse
– then projected on stage in Stockholm

The intercontinental link between
London and Singapore
GÉANT-TEIN3 network link:
2.5 Gbit/s optical connection
London - Singapore
spanning almost 10,000 Km.
TEIN3: third generation of the TransEurasia Information Network (TEIN)
High-capacity Internet for research and
education communities across AsiaPacific.

DVTS and audio/video streaming
on TEIN3
DVTS (Digital Video Transport System) bi-directional Audio/Video
channel over the TEIN3 Link.
Multi-platform video/audio streaming application and hardware solution
for high-bandwidth, low-latency network
currently used for music master classes and conferences
Allows DV-quality video and audio across an IP network using
a fixed network bandwidth
inexpensive consumer-grade video and audio equipment.
First time DVTS supports a live performance across more than 9,000
Km

Testing the TEIN3 link
Test focus:
achievable bandwidth, packet loss, jitter
quality of the connection and its stability
ready for an intercontinental, high quality digital audio/video
transmission in real time.
Tools:
UDPMon
– Software package for investigating network performance, using
UDP/IP frames.
– Able to transmit streams of UDP packets at regular, carefully
controlled intervals
Iperf
– Network tool to generate TCP and UDP traffic and measure
bandwidth performance.

Two special instruments on stage
Two very special musical instruments on stage: the Epigonion and the
Barbiton
Ancient Greek instruments reconstructed by the ASTRA project using
physical modelling
Computer virtual models based on archaeological findings
GÉANT and EUMEDCONNECT2 enabled the computer-intensive
modelling
The Epigonion (a)
and the Barbiton (b)

Original mixture of traditional composition and orchestration and
audification of the GÉANT network
GÉANT Network sonification process:
(a) start from an empty score;
(b) superimpose the (network) graph to sonify;
(c) put notes according to the shape of the graph;
(d) the melody
