Improvements in the local network

Involved people at OAB: Delpino, Di Luca, Lolli, Madama, Merighi, Policastro.

The network hardware installed in the via Ranzani building, before the Observatory move, was a 10Mb/s switched lan. After the move, similar switches, installed in the tower, were ported to the new wing of the building to cover the need for new connections. Moreover the older hardware has been updated and expanded to make it homogeneous with respect to the one installed in the new building. In the new wing, thanks to a joint-project between Department of Astronomy and Osservatorio Astronomico, based on a grant from the University of Bologna, a new Cabletron switch operating at 100Mb/s, has been installed. This switch is connected in ATM on optical fiber (155Mb/s) to the academic network, the GARR backbone and to the switches of the old wing allowing the connection of the whole building.

Concerning the Astronet project, a new Alpha 500/266 workstation has replaced the VAX/VMS 4090. This workstation hosts the national DNS and the WWW Observatory site.
