Network Topology Testing and Traffic Analysis

As networks converge into a single network infrastructure that is used to carry voice, video, data, and wireless traffic, it is critical to use leading-edge test systems to assess functionality, scale, and performance. IxNetwork provides wire-rate traffic generation with service modeling that builds realistic, dynamically-controllable data-plane traffic. IxNetwork offers the industry’s best test solution for functional and performance testing by using comprehensive emulation for routing, switching, multi-protocol label switching (MPLS), IP multicast, broadband access, authentication, carrier Ethernet, data center bridging (DCB), and software defined networking (SDN) protocols. IxNetwork scales to handle the most powerful devices and largest networks.

IxNetwork offers the customization and flexibility to meet the wide range of requirements necessary for testing complex network topologies with thousands of network devices. It emulates millions of routes and reachable hosts and can customize millions of traffic flows to stress data plane performance. Powerful graphical user interface (GUI) wizards and grid controls allow simplified creation of sophisticated traffic flows. Its enhanced real-time analysis and statistics are capable of reporting comprehensive protocol status and detailed per-flow traffic performance metrics.

Multi-protocol visibility with protocol drill-down and control

Service Modeling at Internet Scale

  • Emulate ultra-high-scale network topologies
  • Track up to 4 million flows
  • Generate deterministic traffic profiles and control each profile dynamically
  • Generate real-world application traffic over emulated networks
  • Apply network impairments such as delay, jitter and loss
  • Scale up to 600 test ports per session

Rapid Isolation of Service Violations

  • Debug difficult problems quickly
  • Monitor total service quality
  • Drill-down to traffic class statistics
  • Device-based protocol configuration enables fast configuration of large, complex topologies

Simple Workflow

  • Collaborate on, share, and re-use port, traffic and protocol configurations
  • View statistics alongside protocol and traffic configuration for instant feedback
  • Make quick adjustments based on color-coded indicators of protocol and traffic status
  • Improve productivity with context-sensitive help ribbons

Complete End-to-End System Automation

  • Easily run repeatable, unattended test sessions
  • Capture and replay GUI actions using Macro Recorder
  • Build test scripts that include configuration of your device under test

Other Key Features

  • Easy-to-use protocol and traffic wizards emulate complex networks with the widest selection of layer 2 (L2) and L3 protocols and traffic profiles
  • Dynamic traffic support, with the ability to change rate and frame size on the fly, and dynamically-updated MPLS and PPP traffic without stopping and restarting
  • Advanced measurements, including four latency modes, delay variation (jitter), inter-arrival time, sequence checking, misdirected packets, packet loss duration, and Rx rates
  • Streamlined workflow that exposes all configuration options in context-sensitive ribbons and contains an overview summary of ports, protocols, and traffic with detailed views
  • Collaborative resource management with Resource Manager – divide and conquer large, complex test topologies, compare resource versions and configuration changes, merge resources with easy-to-use wizards
  • Statistics viewer providing summary-level, group-level, and per-flow statistics with sophisticated results filtering and sorting powered by Flow Detective™, enabling real-time analysis
  • Virtual server and cloud testing through virtual test ports
  • Quickly and easily record interactions with IxNetwork and save these recordings as tests for later use with Macro Recorder
  • Multi-field ingress tracking to track flows based on multiple user-defined fields
  • Multi-egress tracking provides a unique ingress/egress results view that compares sent traffic with received traffic, so as to accurately verify what DUT packet field modifications; QoS remarking is easily verified
  • Ability to add custom formulas in any statistics view
  • Powerful reporting with one-click report generation, data analysis, custom report and template builds, customizable charts and graphs, in PDF or HTML formats
  • QuickTests for industry-standard test methodologies, including RFCs 2544, 2889, and 3918, and ITU-T Y.1564
  • Easy one-click TCL, HLTAPI, or HLPAPI automation using ScriptGen, with complete API support – providing complete automation of IxNetwork functions

Advanced Traffic Wizard

IxNetwork on IxVM

IxNetwork builds large-scale emulated network and complex traffic topologies using real-world routing and switching. IxNetwork's large library of L2-3 protocols allows advanced testing of multicast scenarios using IGMP, convergence testing for measuring outage duration during live migration, and LACP.


IxNetwork emulates a wide variety of protocols using Ixia's CPU-based test port. Each test port supports an independent multi-core CPU running protocol emulations under a Linux operating system. Using the IxNetwork test application, each Ixia test port is capable of emulating thousands of routers or bridges with millions of reachable networks and hosts. Users can easily scale the size of emulated topologies by adding additional test ports. Combined with line-rate traffic generation and QoS measurement capabilities, the CPU-based load modules verify advertised topologies and networks for reachability and QoS performance.
