Connections Between Observatories

Connections between observatories are limited by university firewalls


Networks at the University of Louisville and the University of Southern Queensland are connected through Internet2 from Louisville to Sydney, and a high speed network within Australia. From the Toowoomba campus to Mt. Kent a line-of-sight microwave link provides a data rate of 50 Mb/s. From the Louisville campus network to Moore Observatory a commodity T1 line limits data to 1.5 Mb/s.

Outside access to the University networks is limited by firewalls as shown in the figure. Direct control of the telescopes for remote observing is available only through the virtual private networks (VPN's), or through web-based interfaces. At Moore Observatory in the T1 service from campus is switched to servers and operator consoles in the main building, and to computers, and control systems in each enclosure. A separate local area network connects the Moondog server to specialized devices that do not require access from outside the observatory.





Moore Observatory Local Network

Moore Observatory network


Many instruments that are needed for observatory operations are connected to a local network managed by the Moondog observatory server. A local intranet runs from a switch at Moondog to each of the enclosures, and switches in the enclosures enable simple local private connections as needed. A short range WiFi network allows user laptops to connect to instruments behind the Moondog firewall so that operators may have their own laptops connected to the telescopes.
