Subscriber-Aware Forwarding

The GTP Correlation feature is a licensable, robust and intelligent addition to the GigaSMART® engine that enables mobile service providers to monitor subscriber data in GPRS Tunneling Protocol (GTP) tunnels. Because it understands the stateful nature of this protocol, the GTP Correlation feature can match and pass all of an identified subscriber’s control and data sessions to the appropriate analytics, performance and billing subsystems to help ensure an accurate view of the session performance and the subscriber’s quality of experience.

With GTP Correlation, mobile operators can now intelligently forward subscriber sessions to specific tools by filtering on subscriber IDs or tunnel IDs -- from ranges of subscribers down to a specific, high-value subscriber.

Benefits of the GTP Correlation Feature:

  • More efficient, effective tool processing throughput.
  • Improved analytics accuracy from reliable correlation of subscriber sessions.
  • Helps maximize quality of experience and monetizing services with more accurate end-user quality of experience metrics.
  • More reliable accounting, billing, and subscription management.
  • Fewer errors through accurate correlation of subscriber data fragmented in transit.

GigaSMART Features

GigaSMART® offers several essential traffic intelligence services required for deep observability into infrastructure blind spots.

NetFlow Generation

Delivers basic Layer 2–4 network traffic data to analysis tools.

Source Port Labeling

Provides context to packets and identifies behaviors and threats based on network location.

Adaptive Packet Filtering

Identifies patterns across any part of the network packet, including the packet payload.


Targets, identifies, and eliminates duplicate packets, blocking unnecessary duplication and sending optimized flows.

Packet Slicing

Truncates packets while preserving the protocol headers required for network analysis.

Advanced Load Balancing

Divides and distributes traffic among multiple tools based on a variety of data points.

Advanced Flow Slicing

Reduces bandwidth usage by slicing payloads and packets from long data flows.


Provides customizable data protection by overwriting specific packet fields with a set pattern. 


Alleviates blindness of business-critical traffic at remote sites, virtualized data centers, or in the public or private cloud.

Application Visualization

Provides a complete view of the applications running on your network.

Application Filtering Intelligence

Extends Layer 7 visibility to thousands of common and proprietary applications.

Application Metadata Intelligence

Provides application visibility to identify performance and quality issues, and potential security risks.

GTP Correlation

Enables mobile service providers to monitor subscriber data in GPRS Tunneling Protocol tunnels.

FlowVUE Flow Sampling

Provides subscriber IP-based flow sampling.

5G Correlation

Forwards subscriber sessions to specific tools by filtering on subscriber, user device, RAN, or network slice IDs.

SSL/TLS Decryption

Creates a secure channel between the server and the end user's computer or other devices as they exchange information.
