Measure the Quality of Experience of Real-Time, Business-Critical Applications With Converged Multiplay Service Emulations
Problem: Endangered Quality of Experience
In today’s highly competitive landscape, organizations must meet stringent network quality requirements to deliver the best customer experience. However, a widening array of multimedia applications, and an increasing number of users, is making it harder — and more expensive — than ever to validate converged multiplay services and application delivery platforms. Without a way to properly test these services, customer quality of experience is at risk.
Solution: A Highly Scalable and Easy-to-Use Solution for Testing and Validation
IxLoad delivers comprehensive performance testing for validating user quality of experience. IxLoad works by emulating web, video, voice, storage, VPN, wireless, infrastructure, and encapsulation/security protocols to create realistic scenarios. A modular system design allows IxLoad to scale with your infrastructure while real-time quality of experience metrics let you drill down to quickly identify network degradations and isolate breaking points. Since IxLoad is as easy to use as it is effective, you don’t have to be a protocol expert to achieve complete end-to-end service validation.

IxLoad FAQs
IxLoad is a stateful application traffic generator and analysis tool that emulates realistic user behavior (HTTP, video, VoIP, gaming, cloud apps) while also testing security devices (firewalls, proxies, VPNs, DDoS defenses). It measures KPIs like throughput, latency, session setup rate, and QoE.
- IxNetwork → Protocol and routing/emulation at scale (L2–L3 focus).
- IxChariot → Lightweight endpoint-to-endpoint application benchmarking (pre-deployment checks).
- IxLoad → Stateful application traffic + security testing (L4–L7), emulating millions of users and real apps simultaneously.
IxLoad supports:
- Web / OTT apps (HTTP / HTTPS, YouTube, Netflix, Facebook)
- VoIP / Video (SIP, RTP, Skype, Zoom, WebRTC)
- Enterprise traffic (Exchange, Citrix, Office 365)
- Security scenarios (malware traffic, DDoS, SSL / TLS inspection)
- Custom scripts for proprietary apps
Yes. A major use case is validating NGFWs, SSL VPNs, IDS / IPS, WAFs, and DDoS appliances under realistic traffic loads. IxLoad can mix clean application traffic with malicious payloads to test detection, blocking, and performance impact.
IxLoad scales from lab setups to carrier-grade testing:
- Physical appliances (high-throughput chassis / blades)
- Virtual Edition (IxLoad VE) for cloud and virtualization (AWS, Azure, VMware, Kubernetes)
- Millions of concurrent users/sessions with elastic scaling
Yes. IxLoad includes:
- REST API
- Python and Tcl scripting
- Integration with Jenkins, Ansible, and CI / CD pipelines
This allows continuous performance / security regression testing in DevOps workflows.
IxLoad provides detailed dashboards and reports, including:
- Bandwidth utilization
- Concurrent sessions / CPS (connections per second)
- Application response times
- MOS scores for VoIP
- Security test pass / fail and blocked attack rates
- SLA validation reports
