Software-only test suite ushers in VoIP tests

Ixia Communications Inc. is introducing its first software-only test suite for VoIP as part of a multimedia testing strategy unveiled at the September VON show. IxVoice Lite is a downloadable application to test VoIP functionality, though Ixia's executive director of product management Bruce Miller said the company hopes it will serve as an introduction to more full-functionality tests residing on the company's Optixia chassis.

The IxVoice suite allows testing of video over Real-Time Protocol, voice, ringtones and T.38 fax, with the Lite version testing all environments from a workstation-based simulation environment. The software allows correlated "real-world" calls to be generated, simulating failed-call scenarios and showing exposed protocol state machines.

The more demanding environment of mixed voice, data and video IP testing has increased customer interest in Ixia's custom engineering, which offers consultative services for VoIP applications deployment and in-service testing.

Ixia showed the Aptixia Triple Play test application for Optixia, in which both carriers and equipment vendors can emulate more than 40 million Web users connecting at up to 1.5 million uses per second. Voice can be tested at rates of more than 60,000 simultaneous calls and video subscriptions at more than 30,000 standard-definition video streams.

A new hardware subsystem called the Content Processing Module uses 16inches of rack space in the Optixia chassis, and dissipates less than 1,900W. The same Optixia platform can test IP and multiprotocol label switching transport performance at the application layer.
