Filter Matching Packet Content

The Adaptive Packet Filtering feature is a licensable addition to the GigaSMART® engine that can identify patterns across any part of the network packet, including the packet payload. Adaptive Packet Filtering can use this awareness to filter based on packet contents beyond Layer 2, 3, and 4 headers, including URLs, patterns in BitTorrent packets, basic application identification, and specific encapsulation protocols. Operators can use Adaptive Packet Filtering to define custom signatures through regular expressions to match their specific applications. With Adaptive Packet Filtering the signatures can also identify sensitive data and obscure it before forwarding to tools.

Adaptive Packet Filtering can identify, and forward packets based on multiple complex headers and encapsulations, including MPLS, VXLAN, MAC-in-MAC, IP-in-IP (IPv4 and/or IPv6) and others.

Benefits of the Adaptive Packet Filtering Feature:

  • Identifies and filters packets which use dynamic IP addresses and non-standard ports.
  • Filters web-based applications that share the same L2-L4 header information. 
  • Removes bandwidth-hogging traffic such as streaming services which doesn’t require monitoring and storage.
  • Obscures sensitive data such as credit card and identification numbers wherever they may occur within the packet before sending the packet to monitoring and storage tools.

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.
