The DLR backend - Data linking and provision
Every day, DLR generates enormous volumes of data related to complex information and communication technologies. In order to evaluate, link and retrieve this data for research purposes, a central system component is required to bring it together – the backend.
What is the purpose of the DLR backend?
The backend of the DLR Institute of Transportation Systems is a powerful underlying infrastructure for handling data generated during the research and testing of (inter)urban mobility solutions. All simulation and testing infrastructure comes together here.
The backend consists of:
- a powerful database server
- a central server pool
- comprehensive middleware components
This supports the development of complex information and communication technologies for new transport solutions and enables the networking of the Institute's various services and large-scale research facilities. The backend provides a high-performance virtualisation environment as well as database and archive functionalities. This ensures that important data remain available in the long term and assists the development of new insights by linking data from sensors in different testing, monitoring and measuring systems.
Due to this range of applications, the backend now serves as the central service and data infrastructure for the Institute’s research activities.
To continue to meet the requirements of in-house projects, the DLR backend is subject to constant further development and renewal.
How you benefit from DLR's IT infrastructure
- Data managed in the backend (such as traffic data) can be made available to customers and external partners
- Data are always up to date thanks to continued development of the backend
- Access to information on the traffic situation in the field, locations of traffic lights and signs
- Networking of various services and large-scale facilities (large-scale facilities can be booked by customers for their own tests)
Application
- Storage of operational, test, and measurement data from the large-scale facilities
- Provision of virtual machines that map specific services of the individual large-scale facilities
- Provision of infrastructure for evaluation and analysis, web services and other middleware services
- Mobile devices can retrieve the data in various formats via a WebSocket or a Rest interface.
