AI-based network operation centre space optimisation

DT Technik leverages a data-driven approach for efficient utilisation of its facilities

End-to-end digitalisation of the processes

In 2022, DT Technik approached T-Systems to create a solution that would enable them to effectively utilise space in their network operation centres (NOCs). A key priority was to automate the interpretation of the NOC layouts that were available as graphical data in Microsoft Visio and thereby reduce manual research time.

The challenge

Network operation centres are very crucial for business organisations that always require high availability. Employees managing NOCs need to monitor one or multiple networks for any conditions that may require special attention to ensure uninterrupted services. In this instance, the customer was struggling to optimise their NOC spaces because the plans were originally in manually prepared MS Visio drawings.

DT Technik employees would consult these drawings for manual research activities, for example to plan for racks and optimise the available space. This was a very time-consuming task, and it also made computer-aided optimisation processes impossible. The customer needed a solution that would help recognise the objects in the Visio drawings and relate the objects to the texts in the drawings.

The cooperation with T-Systems regarding the integration and usage of different approaches, including ML technology as well as rule-based algorithms, advanced the project to the next level.

The solution

T-Systems have been pioneers in data space technology for over five years now. With their deep know-how in the AI/ML space, they developed a machine-learning-powered microservice called “Data Transformator”, which combines domain-expert-driven rules with computer vision deep learning within an ensemble model. This model, called “deep object detection model”, enabled automation of Visio object recognition and interpretation of Visio drawings. The Visio files were parsed and analysed for domain objects. The detected domain objects were served via a dedicated REST API and front-end application. Then, the results were saved in a relational database (PostgreSQL). The implementation of automation scenarios for the specialist pages was made possible through the automated assignment of operating points. The detection system was thoroughly monitored and tested against the label data validated by domain experts to ensure quality.

The customer benefit

With the AI-based automation solution provided by T-Systems, the customer was able to save on manual effort and time and focus on their core tasks. The solution also helped them achieve process and system optimisation, resulting in reduced operational costs. Data forms the backbone of any AI-based initiative. The solution provided by T-Systems helped the customer to achieve effective data management and cleansing, which, in turn, provided a valuable data feed for a holistic digital twin of the network centre. The customer’s future migration needs are also addressed with this solution as T-Systems, with its forward-thinking approach, has established a future-proof platform architecture comprising a modular structure.
