Qualified and Compatible Environments

IxLoad VE is designed to work best when used in a qualified environment. Our recommendation is to always use one of the qualified versions of the virtualization platforms.

IxLoad VE is also compatible with different environments. In case there are issues encountered in these environments, Ixia will make reasonable efforts to address them, but cannot guarantee specific outcomes or results. In such rare cases, the proposed solution is to use the qualified environment.

IxLoad delivers a wide variety of fully stateful protocols to emulate a complete multiplay user environment. It delivers a sophisticated subscriber modeling capability that enables users to replicate the dynamic nature of subscriber behavior. Ixia’s virtual chassis and load modules empower IxLoad to generate city-scale traffic. This, along with comprehensive network support, advanced test timelines, and automatic goal-seek fine-tuning to meet test objective, enables users to comprehensively assess the performance of their service delivery networks and determine application-level performance with a single integrated solution.

Validating virtualized assets

Problem: Questioning the cloud

With its promise of cost savings and easy deployment, cloud computing is redefining IT environments. But while virtualization can glean greater value from data center resources, it can also add new layers of complexity to server architecture and network infrastructures. In fact, in order to justify migrating to the cloud, organizations need to be able to deliver the same—or better—performance than traditional networks.



Solution: An easy and elastic tool for testing and validation

IxLoad VE supports complete functional and performance testing of virtualized servers and 10GE converged network adapters (CNAs) for cloud computing environments. Using Ixia Virtual Load Modules, IxLoad VE is able to test a host of virtualized assets, including firewalls, deep packet inspection (DPI) devices, load balancers, and other network devices.

IxLoad VE works by emulating web, video, voice, storage, VPN, wireless, infrastructure, and encapsulation/security protocols to recreate real-world IT scenarios. A modular system design ensures it can scale with growing infrastructures. And because network degradations and breaking points demand fast remedial action, IxLoad VE consistently delivers real-time quality-of-experience metrics. What’s more, IxLoad VE’s user-friendliness means that even protocol novices can achieve end-to-end service validation. 

Key Features

  • Delivers end-to-end testing of converged application delivery infrastructure and services
  • Provides elastic-scale performance for growing infrastructures
  • Features a simple OVA deployment model and flexible, pay-per-use licensing
  • Enables seamless application performance validation across physical and virtual networks using either IxLoad-VE or standard IxLoad
  • Supports VMware ESX/ESXi and KVM hypervisor
  • VMone combines our Virtual Chassis and Virtual Load Module into a single VM, offering IxLoad VE users a simple deployment option and faster testbed generation
