Demo area
The demonstration will show a practical use of dynamic, on demand circuit creation across European NRENs for the purpose of transferring radioastronomy observation data. Such data can be collected only at specific times and must be sent immediately from radiotelescopes to JIVE correlator in Dwingeloo/Netherlands. In this demonstration we will show the creation of multiple international cross-domain paths from the radio-telescopes of Astronomy Center of Mikolaj Kopernik University in Piwnice/Poland and Jordell Bank Observatory in Lower Withington/England. The high bandwidth generated by e-VLBI observations is best transported over dedicated connections. Currently, static (always-on) lightpaths are in use for e-VLBI, even when no observation is running. The Bandwidth-on-Demand service over international distances would allow for a more efficient and flexible network usage for e-VLBI. The NSI protocol is a new standard developed in the OGF, that allows the creation of such international paths, regardless heterogeneous environment constraints (e.g. different transport technologies, incompatible provisioning tools). NSI has been adopted by the GÉANT BoD service and multiple European NRENs. Network domains involved in the demonstration are using different network provisioning tools (e.g. OpenDRAC, AutoBAHN) with NSI interfaces attached, enabling inter-domain communication and the automated creation of international lightpaths upon request from the end-user. The demonstration will not only present the creation of circuit, but will give a background on how NRENs and end-users are able to collaborate and integrate various services (e.g. provisioning, monitoring, topology information exchange) in automated manner, delivering resources for scientific community in a fast, yet reliable way. During the demonstration, we will present the advantage of dynamic provisioning over statically configured circuits.
