Traffic Detection Function & PCEF Solution

Put your business objectives into action

In the complex world of real-time policy and charging enforcement, interoperability and scalability are key to achieving your goals. Allot’s Policy and Charging Enforcement Function (PCEF) and Traffic Detection Function (TDF) solution, ensures you can deploy services rapidly, integrate seamlessly, and scale as you rollout new services.


Part of the SmartPCC solution, Allot TDF/PCEF interoperates with Allot PCRF as well as with multi-vendor PCRF and OCS/OFCS equipment.


Generate new revenue as you meter subscriber usage

Allot TDF accurately classifies and meters data usage per application, user, and device. It delivers these granular data records in real time to the PCRF and OCS/OFCS elements in your network. The Allot PCEF (or other network element) then enforces traffic management and charging policy with high granularity so you can ensure that your OTT applications and services are performing optimally according to network conditions and subscriber expectations.


Charging policy can be based on:

  • Usage caps
  • Top-up options
  • Zero-rating
  • Subscriber location
  • Service chaining
  • Or any set of conditions in the service plan


Real-time Convergence. Highest Scalability.

As a single point of integration for traffic classification, management, charging, and steering, Allot PCEF/TDF solutions, powered by the Allot Service Gateway, enables unified traffic detection and policy enforcement across any mix of access technologies.


Clustering many Allot Service Gateway platforms to work as one lets you scale PCEF/TDF throughput up to Terabits per second, while maintaining accurate traffic classification and control even when asymmetric upstream and/or downstream IP flows are processed by different platforms.


Allot’s intelligent PCEF/TDF functionality, whether physical or virtual, complies with 3GPP standards and interface specifications (Diameter Sd/Gx, Sy, Gy, Gz) to assure maximum efficiency together with higher scalability and performance than any other PCEF/TDF solutions.
