Traffic Detection Function (TDF) is fast becoming an important element in the mobile networks due to the increasing complexities in managing data services, demand for personalization and service differentiation. TDF provides Communication Service Providers (CSPs) an opportunity to capitalize on analytics for traffic optimization, charging and content manipulation, working hand in hand with policy management (PCRF) system. TDF enforces traffic policies based on pre-set rules or dynamically determined rules by the PCRF on data flows in real time. TDF was introduced together with Sd reference point as means for traffic management in the Release 11 3GPP specifications using Layer-7 traffic identification.
