GÉANT AND TEIN3: BRINGING CULTURES TOGETHER ACROSS CONTINENTS Domenico Vicinanza, DANTE Arts and Humanities session Terena Networking Conference 2010 Vilnius, Monday 31 May 2010 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 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 connect • communicate • collaborate The collaboration and the network 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 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 TransEurasia Information Network (TEIN) High-capacity Internet for research and education communities across AsiaPacific. connect • communicate • collaborate The Technology: DVTS The network tests 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 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. connect • communicate • collaborate UDPMon tests (Singapore – Stockholm): Bandwidth tests and packet loss 50 bytes TEIN3Link_Singapore-Stockholm 1000 Recv Wire rate Mbit/s 100 bytes 200 bytes 800 600 400 600 bytes 100 800 bytes % Packet loss 400 bytes 1000 bytes 1200 bytes 200 1400 bytes 1472 bytes 0 0 10 betw een20frames us 30 Spacing Bandwidth available 40 50 bytes TEIN3Link_Singapore-Stockholm 100 bytes 80 200 bytes 60 400 bytes 40 600 bytes 800 bytes 20 1000 bytes 0 1200 bytes 0 10 betw een20frames us 30 Spacing 40 1400 bytes 1472 bytes 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! connect • communicate • collaborate Iperf results DVTS Traffic sim ulation, from Malaysia to Sw eden - Received Traffic 35 35 30 30 25 25 20 20 Mb/s Mb/s DVTS Traffic sim ulation, from Malaysia to Sw eden - Generated Traffic 15 15 10 10 5 5 0 0 0 500 1000 1500 2000 tim e (10 seconds bins) Traffic transmitted 2500 3000 3500 0 500 1000 1500 2000 2500 3000 tim e (10 seconds bins) Traffic received Simulating DVTS traffic from Malaysia to Sweden Comparing generated and received traffic: perfect matching!
