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 and the network

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 betweenLondon and Singapore
GÉANT-TEIN3 network link:
2.5 Gbit/s optical connection
London - Singapore
spanning almost 10,000 Km.
TEIN3: third generation of the Trans-Eurasia Information Network (TEIN)
High-capacity Internet for research and education communities across Asia-Pacific.

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, jitterquality of the connection and its stabilityready 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

Music
World premiere
Traditional Western musical scales and tuning
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
