AutoBAHN (GÉANT2) is a research activity to engineer, automate, and streamline the inter-domain setup of guaranteed capacity (Gbps) end-to-end lightpaths. It is a joint research activity of GN2, a European Commission-funded project with all the European Research and Education networks as partners. Its Inter-Domain Controller (IDC) is compatible with Internet2 and ESnet.
SCARI/e is a distributed software correlator running on the DAS-3 cluster at UvA, to be used for real-time e-VLBI, integrated with advanced networking technologies. The SCARI/e project is a collaboration of JIVE, UvA and SARA, and is funded by the Netherlands Organisation for Scientific Research (NWO). One goal is to replace the current hardware correlator at JIVE with distributed computing – which will be more powerful, more flexible, and less expensive. Another goal is to replace the physical shipment of magnetic media to JIVE from radio telescope sites with real-time streaming of data via high-bandwidth optical networks.
At GLIF 2008, a real-time correlation using AutoBAHN and SCARI/e was conducted with European sites (in Dublin, Poznan, Zagreb and Athens).
For SC08, the demo was extended to connect European sites (in Dublin, Poznan, Zagreb, Athens and Lisbon) to MIT Haystack in the US over Internet2-DCN, where AutoBAHN was used to interoperate with Internet2 Phosphorus.
Note: This demonstration did not use TransLight/StarLight; rather, GÉANT2 links to the US or the Internet2 link from New York to London were used. However, it does leverage networking investments by US and European NRENs in international transatlantic connectivity.
