The local area network (LAN) infrastructure comprises about 80 switches with approximately 2,800 LAN ports in more than 100 different (V)LANs. All DLR/EOC sites and receiving stations are connected by the central DLR-wide area network (WAN) which also provides Internet access. In addition to being protected by the DLR firewall the network systems are safeguarded by separate firewalls at each individual site.
Servers, storage and archiving systems are being operated by EOC staff. The network is partially run by EOC staff, partially by an external service provider. Parts of the network subsystems used by the European Space Agency (ESA) are operated directly by ESA.
Accordingly, the responsibilities for the IT Engineering team include:
The IT Engineering Team also includes the EOC IT manager and IT security administrator. Specifications and guidelines relating to IT services are coordinated among the EOC institutes, DLR’s central IT management department and the external IT service provider.
