Logically Divide Traffic Among Ports

The Load Balancing feature is a licensable addition to the GigaSMART® engine that divides and distributes traffic among multiple tools, so network and security visibility can scale beyond the capacity a single tool can provide. Using effective load balancing techniques, traffic and requests can be distributed based on a variety of options: bandwidth, cumulative traffic, packet rate, connections, round robin, and stateless hashing.

Load Balancing allows operators to include any port in the node as a member of the tool group, as well as ports operating at different speeds. Operators can also use load balancing to weight server-traffic delivery on a per-port basis, to accommodate bandwidth differences or processing capabilities of attached tools, or match and load balance based on inner addressing within encapsulated and tunneled packets.

Benefits of the Load Balancing Feature

  • Helps scale network infrastructure by dividing traffic between two or more tools when volume exceeds a single tool or port's capacity.
  • Improves efficiency by weighting traffic application delivery to match tool processing capabilities or port bandwidth capacity.
  • Automatically redistributes traffic to remaining tools in case of tool failure. Automatically restores tool availability for new traffic upon failed tool recovery.
  • Enables load balancing of encapsulated or tunneled traffic (GTP, GRE, or ERSPAN).
  • GTP-aware load balancing helps mobile service providers ensure improved response time and performance for individual subscribers or groups.

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.
