Centralized Intelligence
CONTROL PLANE
The Quant Azimuth Control Plane is the operational core of our DPI platform for policy, traffic, and system management. It governs how data is processed, how policies are enforced, and how the system scales to meet national deployment demands. Working closely with the Data Plane and Mediation Layer, the Control Plane enables intelligent, automated, policy-driven network behavior.
Core Components of the Control Plane
1. Apache Kafka Cluster
Acting as a high-performance, distributed messaging backbone, the Apache Kafka Cluster enables seamless communication between system components, including:
• Ingesting high-volume data streams from DPI units in the Data Plane.
• Distributing traffic data in real-time to the Application Server Cluster.
• Decoupling data producers (i.e., DPI probes) from consumer application logic for flexible scaling.
2. Application Server Cluster
A horizontally scalable cluster hosting multiple instances of our intelligent Application Servers. Built for fault tolerance and elastic scalability, including:
• Processing traffic intelligence received via Kafka.
• Implementing core traffic management and subscriber-centric functions.
• Scaling dynamically based on network load and business requirements.
• Supporting load balancing to optimize performance and redundancy.

Key Functions of the Control Plane
Subscriber Management
• Tracks user identities, sessions, and profiles in real time.
• Integrates with AAA systems and subscriber databases.
Policy Control
• Creates and enforces network policies based on application, user, time, or location.
• Interfaces with PCRF/PCF via Gx/Gy for 3G/4G/5G environments.
• Drives application-aware services and differential data plans.
Traffic Management
• Dynamic shaping, blocking, prioritization, and redirection of flows.
• Real-time policy triggering based on application type or behavior.
Congestion Detection & Heavy User Detection
• Detects network congestion across access and core segments.
• Automatically enforces load shedding or throttling rules.
• Identifies subscribers who consume disproportionate resources.
• Enforces fair use policies, throttling, or premium upsell options.
Quality of Service (QoS) Management
• Monitors and improves user experience across services and applications.
• Adjusts resource allocation based on real-time performance metrics.
Network Performance Monitoring
• Aggregates and analyzes KPIs across different interfaces, access types, and locations.
• Detects service degradation early and triggers mitigation actions
Security Threat Detection & Mitigation
• Flags unusual or malicious traffic patterns, encrypted tunnels, or rogue apps.
• Enables real-time blocking or alerting for known and unknown threats.
Regulatory Compliance (Blocking & Reporting)
• Enforces lawful interception triggers.
• Generates required reports for regulatory and national security use.
User Behavior Analysis
• Profiles user trends, usage patterns, and service consumption.
• Enables targeted policy creation and subscriber insights.
Location-Based Performance Analysis
• Tracks performance and behavior by cell, gateway, or region.
• Supports infrastructure planning and service quality audits.
Control Plane Scalability & Resilience
Designed for national-scale operations, the control plane delivers the scalability and resilience needed to sustain constant growth and unpredictable demand. Its elastic, load-balanced architecture ensures consistent performance, high availability, and uninterrupted service even in peak and mission-critical conditions.
Elastic Application Server Instances
• Scale up/down based on network load or policy complexity.
• Ensures responsive performance even during peak traffic.
Load Balancing Across All Components
• Ensures optimal resource utilization and prevents bottlenecks.
• Supports automatic failover and service continuity.
Built for Carrier-Grade Availability
• High availability architecture with clustering, replication, and fault tolerance.
• Suitable for 24/7 mission-critical national deployments.
Control & Coordination with Other Layers
The control plane maintains real-time interaction with the data plane to enforce policies dynamically and consistently across the network. Through standardized interfaces and mediation integration, this ensures accurate session-level control while aligning reporting, compliance, and security outcomes with live policy states.
Data Plane Interaction
• Real-time communication over Gx/Gy interfaces for dynamic policy enforcement and charging.
• Instructs DPI units to act on a per-session basis based on subscriber behavior or traffic type.
Mediation Layer Integration
• Informs data normalization and reporting logic based on live policy states.
• Aligns reporting outputs with regulatory and security requirements.
