IxLoad

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.

IxLoad

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.

APPLICATION LAYER PROCOTOLS 

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 model the dynamic nature of subscriber behavior. Ixia’s purpose-built 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.

Application Mixes

AppLibrary – A continually expanding and updated library of pre-defined application flows and application mixes of the most current internet applications

Sophisticated SuBSCRIBER MODELING

To closely model real-world device and network load, IxLoad uses a unique approach called subscriber modeling that enables users to:

  • Emulate multiple application services per subscriber or user, including service sequencing
  • Model traffic usage over time for each application, with advanced timelines
  • Simulate the temporal nature of subscribers connecting and disconnecting from the network in a dynamic manner
  • Completely control usage profile—particular websites visited, e-mail servers used, transfer sizes, channel changing behavior, streaming content, protocol options, etc.

AppLibrary

In addition to the fully stateful protocols emulations, IxLoad includes AppLibrary, and extensive library of pre-defined application flows that simulate end-user interactions and devices. It speeds and simplifies testing application performance with blended application mixes. AppLibrary uses Ixia Application and Threat Intelligence (ATI) program to ensure the flows are current and are updated on a monthly basis.

Quality of Experience Metrics

IxLoad delivers an extensive real-time statistics viewer with pre-defined, customizable views.

  • Protocol-level statistics for in-depth functional testing, as well as real-time test-level statistics ideally suited to scale testing
  • Aggregate statistics are displayed hierarchically, with the ability to drill-down to network groups, application/activity-level and port-level statistics.
  • Analyze the QoE impact of services on per-user, per-IP, or per-VLAN basis
  • Set filters on statistics by specifying conditions to isolate errors and failures
  • Use CSV files to capture a single results view or at the global level to capture all results in real-time; an integrated CSV viewer enables viewing of large-result files

Resource Manager

A common pain-point for users was the lack of a collaboration tool to aid in incrementally building configurations and sharing the expertise of different team members. IxLoad Resource Manager is a central

resource manager

repository used to save, store, and reuse the various components of an IxLoad test. This allows multiple users and teams to share the different components of a test like network, traffic, activity, and protocol settings, full configuration files, external files, and more. Sharing of resources between teams increases productivity and saves precious time. You can even use Resource Manager as a light-weight version control system, storing external files like DUT configurations and  topology diagrams so others know where to access the latest (or even an earlier) revision.

Reports

IxLoad provides built-in reports that are visually rich and contain concise performance metrics at test, protocol, and port level.  Any report template can be customized, or create your own templates that can be shared. If also includes IxReporter Designer Studio to create new charting and analytics using all the raw metrics from IxLoad rest results as well external sources.
