Policy and Charging Enforcement Function (PCEF)

Powering Network Security & Policy Enforcement with DPI & PCEF

Deep Packet Inspection (DPI)

At Protei, we leverage Deep Packet Inspection (DPI)—a cutting-edge technology that inspects every detail of data packets as they traverse the network. This enables us to precisely identify, categorize, and manage traffic in real-time.

Why Protei Uses DPI:

Advanced application recognition and traffic analytics
Threat detection and security enhancements
Traffic shaping for optimal performance
Insights for proactive network management

Packet Data Enforcement Function (PCEF)

Within Protei’s network architecture, PCEF acts as the enforcement agent within the Proxy Gateway (PGW). It manages user sessions and enforces policies based on DPI insights, ensuring your network adheres to operator policies, guarantees Quality of Service (QoS), and supports precise billing.

Why Protei Supports PCEF:

Real-time application of QoS policies
Secure, compliant, and fair data delivery
Dynamic session management for mobile networks

How DPI & PCEF Work Hand-in-Hand at Protei

By integrating DPI within PCEF, Protei creates a network ecosystem that is:

Highly Secure: With deep traffic visibility, quickly detect and prevent threats.
Efficient: Optimize bandwidth, reduce congestion, and improve user experience.
Reliable: Enforce policies to ensure fair usage, quality, and fair billing.
Future-Ready: Adapt to new technologies and increasing data demands with flexible policy enforcement.
