Network prediction and performance

- Status In the pipeline
The purpose of DCB is to maintain a safe distribution of traffic to manage among controllers and avoid traffic overload. It is supported by traffic demand forecasts within a collaborative framework. Advanced DCB addresses the need to integrate network planning into this process and improve demand forecasts using shared business trajectory information and big data.
SESAR is looking to establish a performance driven network management culture as an evolution of the current process, which is mainly focussed on delay reduction. This requires a shared situational awareness and an agreed set of performance indicators to be used for real time performance monitoring, trade-off analysis, and
what-if impact assessments. These indicators need to be dynamically selected according to network geographic interest scales and specific time horizons. The research identifies common local, regional, and sub-regional network performance indicators and their relationship to a selected set of network congestion mitigation
strategies. The aim is to create a transparent performance-driven network management culture, which shares constraints and agrees solutions among all stakeholders.
For example, network complexity prediction will enable both the identification of situations where the traffic complexity in a specific area is out of equilibrium or out of proportion compared to other directly related areas, as
well as the assessment of impact on airspace capacity, predictability, flexibility and safety. The information can be used to implement dynamic airspace management and resource allocation measures, such as dynamic sector configuration and dynamic mobile areas, as well as traffic management measures such as re-routing and level capping, to help solve hotspots and complexity problems.
