Multiplay Service and Application Delivery Platform Testing

IxLoad is the industry’s most scalable solution for testing converged multiplay services and application delivery platforms. IxLoad emulates data, voice, and video subscribers and their associated protocols for ultra-high performance testing. Unique and advanced subscriber modeling capabilities create realistic scenarios to validate subscriber quality of experience (QoE). To speed test configuration and ensure optimal realism, IxLoad simulates today’s most-used Internet, video, voice, storage, security, VPN, wireless, infrastructure, and encapsulation/security protocols.

Flexible and Scalable Platform to Meet Your Needs

IxLoad is powered by Ixia physical and virtual load modules and chassis, which offer the flexibility for:

  • Massive-scale, native 10/40/100GbE testing using PerfectStorm 10GbE, 40GbE, and 100GbE native interface load modules and XGS12 chassis.
  • Enterprise-wide 1/10/40GbE testing using PerfectStorm ONE appliances.
  • Seamless use with Ixia’s BreakingPoint application and security test application for a single, more powerful system that can validate every element of the data center.
  • High-density 1/10GbE testing with up to 80Gbps of multiplay traffic, and 20Gbps of IPsec traffic using the Xcellon-Ultra line of load modules that are specifically designed to be used with IxLoad.
  • Virtual environment testing with IxLoad/VM, which uses Ixia’s IxVM virtual chassis implementation, a software implementation of Ixia’s platform that allows virtual machines (VMs) on blade servers to act as Ixia test ports. The virtual test ports can be used independently or in conjunction with chassis based ports.


  • Flexible framework offering in-depth features for functional and performance testing
  • Emulates a complete multiplay user environment by running data, voice, and video services simultaneously
  • Models sequences of operations across multiple protocols to model multi-step subscriber operation
  • Real-world user behavior by employing “think” times, configurable responses, impairment, etc.
  • Virtual server and cloud testing through virtual test ports
  • Constructs ramp-up, ramp-down user sessions – linear, step, and adaptive modes
  • Integrated automation
  • Wizards easily create complete tests and network topologies
  • Seeks test objective goals automatically, including concurrent connections, connection rate, simulated users, and throughput
  • Traffic mapping configures IP addresses and VLANs that will send and receive traffic to and from each other
  • Built-in impairment function with multiple impair profiles allows introduction of latency, jitter, and dropped packets, fragmentation, and upload/download bandwidth limit to be applied on transmission
  • IPv4 and IPv6 addressing
  • Uses link layer protocols, including PPPoE, IPsec, and DHCP
  • Layer 2/3 authentication mechanisms such as WebAuth, 802.1x and NAC
  • Real-world network configurations, including multiple sub-networks, unique MAC addresses, 802.1q, 802.1p, and emulated router support

Troubleshooting and analysis

  • Packet analyzer plays media packet payloads in a media player
  • Analyzes quality of experience (QoE) per subscriber by supporting video quality metrics (MDI, VQMon) and voice quality scores (MOS)
  • QoE detective – features per-subscriber, per-IP or per-VLAN statistics to measure application performance information across multiple services, in real-time
  • Network diagnostics of network-layer statistics in real-time for complete insight into test operation, allowing debugging and troubleshooting of complex network configurations
  • Per-test network failure thresholds, preventing minor mis-configurations or network issues from stopping a valuable test run

IxLoad Virtual Edition (VE)

IxLoad VE is designed to work in virtualized environments using Ixia’s unique Virtual Chassis and Virtual Load Modules implementation. The IxVM platform is a software implementation of Ixia’s hardware platform, allowing virtual machines (VMs) on generic servers to act as Ixia test ports. These virtual test ports can be used independently or in conjunction with chassis based ports. Software-based stream and protocol engines in the virtual ports provide the same traffic generation and analysis as Ixia’s hardware-based product portfolio.
