Eliminate Unneeded Packet Data

The Packet Slicing feature of the GigaSMART® engine truncates packets while preserving the portion of the packet (the protocol headers) required for network analysis. Packet Slicing can parse variable header packets, starting slicing after a named header (IP, TCP, etc.) with or without VLAN and other tags. Thus, there's no need to rely on a fixed offset to slice packets.

Packet Slicing removes payload that may be irrelevant to network monitoring and security analysis. This reduces tool throughput and disk space while improving performance and data retention. It also removes sensitive data before it is stored, which makes regulatory and privacy compliance easier.

Benefits of the Packet Slicing feature

  • Removes sensitive information from each packet, thus helping address compliance and confidentiality requirements.
  • Improves tool performance by eliminating unnecessary transmission of unneeded packet payload.
  • Increases storage capacity by giving tools more room to store the important portions of each packet.
  • Increases data retention time on forensic or network recorders.
  • Reduces needed disk space for backup traffic by up to 95%.

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.
