IXIA SELECTS TELCHEMY'S VIDEO PERFORMANCE MONITORING TECHNOLOGY FOR IPTV AND TRIPLE PLAY TESTING

Integrates Telchemy’s VQmon IPTV Video Performance Analysis Technology

DULUTH, Ga. – June 19, 2006 – Telchemy, Incorporated, the global leader in Voice and Video over IP fault and performance management technology, announced that Ixia, a leading, global provider of IP performance test systems, has licensed Telchemy’s VQmon/SA-VM IPTV performance analysis software for use in its range of Triple Play communications test systems.

VQmon/SA-VM is a highly efficient, fast and compact software agent that monitors IP based video streams in real-time, measures the time distribution of lost and discarded packets using a multi-state statistical model, examines the type of codec, bit rate and other factors and uses a perceptual model to calculate transmission quality and perceptual quality metrics. VQmon/SA-VM can analyze MPEG Transport and RTP based video streams, and provides a wide range of performance and diagnostic data.

“We selected Telchemy’s VQmon/SA-VM technology as it provides accurate real time metrics for IP based Video streams” said Cliff Hannel, Vice President, Acquisitions and Strategy. “Telchemy has an excellent reputation within the industry for the strength of its technology, its leadership in the development of Voice and Video over IP performance management technology and its strong customer focus.”

Ixia’s IxLoad can accurately emulate millions of IPTV Broadcast Video and Video on Demand (VOD) subscribers and the millions of video streams they are viewing. Such large scale emulations enable the performance characterization of key IPTV elements, including video servers, multicast routers, and the video delivery network. VQmon/SA-VM allows IxLoad to provide real-time analysis of video service quality in order to assess the impact of these elements on use Quality of Experience.

“We welcome the opportunity to work with Ixia,” said Alan Clark, Telchemy’s CEO and President. “They are a leader in the field of IP performance test and a pioneer in the emulation of large scale IPTV services.”
