5G and CUPS Correlation

Intelligent visibility for service providers with 5G CUPS and LTE CUPS, the must-have foundation for any 5G transition.

Subscriber-Aware Forwarding in a 5G and CUPS World

In a new 5G or 4G LTE world, where the control and user planes are separated (known as CUPS), obtaining coherent visibility of sessions is more challenging than ever. The physical separation of the user-plane traffic from the control-plane traffic, often in different locations, makes it difficult to associate the GTP user-plane tunnel sessions with the user or equipment identification.

With Gigamon 5G and CUPS Correlation, 5G and LTE CUPS mobile operators can now intelligently forward subscriber sessions to specific tools by filtering on subscriber, user device, RAN or network slice IDs — including ranges down to a specific, unique ID. Other benefits include:

  • More efficient, effective tool processing throughput
  • Improved analytics accuracy from reliable correlation of subscriber sessions
  • Maximized quality of experience and monetizing services
  • Increased reliability in accounting, billing and subscription management

It’s all part of Gigamon Subscriber Intelligence solutions made specifically for service providers.

Plus, be sure to take advantage of our new bundled GigaSMART® apps to be subscriber-aware!

GigaSMART Features

GigaSMART® offers a number of other essential traffic intelligence services required for active visibility into infrastructure blind spots, including:

NetFlow Generation

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

Advanced Flow Slicing

Eliminates these issues by slicing payloads and packets from long data flow.

Source Port Labeling

Provides context to packets and allows tools to properly assess network behavior and threats based on where they are.

Adaptive Packet Filtering

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

SSL/TLS Decryption

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

Packet Slicing

Truncates packets while preserving the portion of the packet (the protocol headers) required for network analysis.

Advanced Load Balancing

Divides and distributes traffic among multiple tools, so network and security visibility can scale.


Targets, identifies and eliminates duplicate packets, blocking unnecessary duplication and sending optimized 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 hosted in a public cloud.

Application Visualization

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

Application Filtering Intelligence

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

Application Metadata Intelligence

Empowers your security information and event management and network performance monitoring tools.

GTP Correlation

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

5G Correlation
