Dynamic Resource Allocation via GMPLS Optical Networks (DRAGON) demonstrates dynamic provisioning across multiple administrative domains to enable Very Long Baseline Interferometry (VLBI). Using simultaneous observations using radio telescopes in the USA (MIT Haystack), Japan (Kashima) and Europe (Onsala in Sweden, Jodrell in the UK, Westerbork in the Netherlands), scientists collect data to create ultra-high-resolution images of distant objects and make precise measurements of the Earth's motion in space.
The HOPI testbed facilitates connectivity between various domains across the globe to simultaneously transfer VLBI data from these stations to the MIT Haystack Observatory at 512Mb/station, where the data is cross-correlated in real time, and then sent to iGrid where the results are visualized in real time.
