e-VLBI Networking challenges
The EXPReS project aims to build a real-time radio astronomy
instrument by networking together a large number of radio telescopes from Europe and around the world. By processing the data from these radio telescopes in the EVN correlator (a special purpose supercomputer) it is possible to reach a much higher sensitivity and resolution than any of the telescopes can attain individually. Transporting this data at gigabit speeds across large distances poses several challenges in the areas of network protocols, hardware and software. The network traffic for EXPReS is partly sent by way of lightpaths, partly routed through the international research and education networks, including NORDUnet.
Both TCP and UDP based protocols are being used, and have specific advantages and disadvantages. This presentation will discuss recent findings and achievements, and future plans for the EXPReS network.
