About this network

The network of the National Radio Astronomy Observatory (NRAO-AS), the US national facility for radio astronomy, funded by the National Science Foundation.

What it's used for

• Networking for NRAO's observatory sites, science operations, and administrative offices.
• Supporting the movement and processing of radio-telescope data — one of the more bandwidth-hungry corners of scientific computing.

Notable

• Federally funded research space, not commercial or eyeball space. Hosts here belong to observatory staff, instruments, and data systems.
• NRAO operates major instruments including the Very Large Array in New Mexico and the Very Long Baseline Array, and takes part in international projects such as ALMA.

Interesting

• Radio astronomy is an unusually demanding network customer: interferometry correlates signals from widely separated antennas, so the observatory's data problem is fundamentally a transport problem.
