An example use case of one of a DAFs would be to send KPIs to a policy control function to decide about security on a noisy node or determine if QoS is unequal across subscribers in a cell. Each logical data analytics module is implemented as multiple instances for different use cases and purposes. For instance, the Big Data module in the management and orchestration layer could be implemented as multiple instances per domain (e.g., RAN data analytics, VNF data analytics, etc.) at different levels (e.g., cross/intra domain). This framework allows for a dedicated data analytic module design at different layers, also enabling cross-layer optimization. Figure 1 depicts the overall integrated data analytics framework
