Network infrastructure for the Very Large Telescope

Already in the early stages of the design of ESO's Very Large Telescope (VLT) and its instruments, it became clear that the network technology in use at the La Silla Observatory could not be simply extrapolated to cope with the VLT requirements. The new generation of instruments has needs for much higher throughput, and also the `remote' operation of four telescopes from a central Control Building forced a new approach.
