Introduction and background

GÉANT network presence and its interconnection to other world regionscapability to create artistic eventsfusing experiences and cultural backgrounds

GÉANT launch event in Stockholm, 1-2 December 2009Exciting 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.


The Technology: DVTSThe network tests


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 networkcurrently used for music master classes and conferences

Allows DV-quality video and audio across an IP network using a fixed network bandwidthinexpensive 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.

The music


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 findingsGÉANT and EUMEDCONNECT2 enabled the computer-intensive modelling

The Epigonion (a) and the Barbiton (b)

Music

World premiere Traditional Western musical scales and tuningOriginal 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


The choreography

The dance performed by the Art Exchange dancers in Kuala LumpurWater-stone symbolism:

Two powers that influence each others behaviour. Water shapes stone, stone shapes water. Choreographed on traditional Malaysian movements and costumes,
