The Network Group within UCL Information Services Division (ISD) develop and maintain UCL's enterprise level networking infrastructure, including networking services for the implementation of research computing services.
Research projects that require external network access are connected both inside and outside the main UCL Campus Network. This allows complete access as needed, but protects both them and the UCL network, while also keeping them separate from other research projects. This is shown in the following diagram.
- MAN Router – connection to the London Metropolitan Area Network, JANET and the Internet.
- Core Router – represents UCL’s internal network.
- Red Cross (by bypass router) – no forwarding path between inside and outside (other than via IFW).
- VRF – (Optional) Virtual Routing and Forwarding – gateway to the external Research Network
Further information about the UCL Campus Network (including diagrams and status reporting) can be found here.
Lightpaths provide a dedicated connection from one JANET institution to another (or in some cases, to an international partner).
Lightpaths should be used for constant or time critical data flows within research projects. Typical examples include high capacity file transfer, remote real-time visualisation, and computational steering.
Key features and considerations:
- Offeres speeds from 100 Mbps to multiple Gbps
- Provides dedicated network capacity (i.e. not shared with other traffic)
- Normally provided on an unprotected basis (i.e. no resilience or availability guarantee)
If you are interested in this service, please contact the Research Computing Network Support Team at rcn-support AT ucl.ac.uk in the first instance. Further information is also available from the JANET Lightpath website.
