The goal of the ESA Informatics Department with respect to communicati
ons is to provide the Agency with efficient and reliable networking se
rvices to meet the users' evolving requirements at the best market con
ditions. It fulfils its mandate by offering a baseline for networking
services targeted at the whole Agency, although networking support for
spacecraft operations is not part of the Department's responsibilitie
s. The general-purpose network engineered and operated by the Departme
nt is called ''ESACOM''. This article describes both the network and i
ts basic service philosophy, as well as its potential role in a future
ESA Corporate Highway.
