Overview

Summary

Information technology (IT) onboard comprises the computer network, a server for data storage, several workplacesworkstations, printer, photocopiers, intranet and a leased line for internet usagelinks.

Components

Central components of the IT are situated in the Umformerraum.

Computer network

All laboratories, chambers and other functional rooms have several network connectors. The connections are bundled in the Umformerraum by 4 Cisco switches. For operational reasons the whole network is subdivided in segments called VLANs. Thereby the network of laboratories, chambers, bridge and other connectors are seperated so that not the whole system failes in case of malfunction.  Still, the single segments are connected in such way that computers of one segment can communicate with other computers, printers etc. via a router and TCP/IP. 

Connection to the internet is enabled from all network connections. A firewall and a package shaper are installed at the transition to the leased line for protection of the whole onboard network.  The package shaper is a protocol filter that only allows  defined network connections such as http and ftp in order to keep network traffic moderate.

A seperate documentation shows you how to connect with your computer to the onboard network:

Leased Line (Internet)

The transmission service is enabled via the satellite Telstar 12 with the KU-band. The orbit position is 15° West. It operates within the European coverage zone (see figure).

The guaranteed availability for the whole ship of 128 kBit/s Upload / 448 kBit/s Download and 768 kBit/s Upload / 2048 kBit/s Download at the best are valid within the 10° elevation contour and the 44 dBW EIRP contour of the European coverage zone.  The bandwidth may reach 1 Mbit/s under very favourable conditions. Operation is possible up to 0° elevation. however, the bandwidth and transmission quality are usually restricted depending on the ship's position and weather conditions.

Iridium internet connection is available after consultation of the ship's command beyond the European coverage zone. UMTS connection can be used for increasing bandwidth to 7,2Mbit/s while staying in German ports.

Workplaces for science staff

Besides computers used only for display of the DShip system two further usable computers are installed in the dry laboratory. Another 2 computers are available for processing multi beam data, data of the sediment and fishing echo sounders and ADCP data. They can only be used by authorized users. Please contact the cruise leadership for obatining these data.

All device-specific computers are only to be used with the equipment and are only available to authorized users. Please contact the relevant person before the cruise.

The computers are part of the fs-heincke.local domain. Registered users are treated as domain users which means that with the login script you are automatically connected to the network "home" via disk drive "H:".
