1. connect communicate collaborate GÉANT AND TEIN3: BRINGING CULTURES TOGETHER ACROSS CONTINENTS Domenico Vicinanza, DANTE Arts and Humanities session Terena Networking Conference 2010 Vilnius, Monday 31 May 2010

2. connect communicate collaborate Agenda Introduction and background The network and the collaboration The technology: DVTS The network tests The music The choreography The final results on stage

3. connect communicate collaborate 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

4. connect communicate collaborate The collaboration and the network

5. connect communicate collaborate 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

6. connect communicate collaborate 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 Trans- Eurasia Information Network (TEIN) High-capacity Internet for research and education communities across Asia- Pacific.

7. connect communicate collaborate The Technology: DVTS The network tests

8. connect communicate collaborate 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

9. connect communicate collaborate 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.

10. connect communicate collaborate UDPMon tests (Singapore – Stockholm): Bandwidth tests and packet loss UDPMon results between Singapore (MYREN POP) and Stockholm (NORDUNet POP) Bandwidth results: transmitting and receiving at line speed (1Gb/s) Packet loss results: no packet loss! Bandwidth availablePacket loss

11. connect communicate collaborate Iperf results Simulating DVTS traffic from Malaysia to Sweden Comparing generated and received traffic: perfect matching! No packet loss Traffic transmitted Traffic received

13. connect communicate collaborate 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) Photo courtesy of F. Baghino and F. Ugozzoli, VisArc Studio, Parma, Italy for ASTRA

14. connect communicate collaborate 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

15. connect communicate collaborate The choreography The dance performed by the Art Exchange dancers in Kuala Lumpur Water-stone symbolism: Two powers that influence each others behaviour. Water shapes stone, stone shapes water. Choreographed on traditional Malaysian movements and costumes, The dancers in Kuala Lumpur
