Texas Instruments and Network Physics Collaborate to Deliver Optimized End-User Experience for IP-Based Services

TI's PIQUA system is a standards-based, embedded capability in IP endpoints, including CPE devices and access and infrastructure media gateways, which gathers and reports real-time operational and
experiential data from equipment used to deliver services such as VoIP and IPTV, said Debbie Greenstreet, director of service provider strategic marketing, Texas Instruments. Working with Network Physics, our PIQUA system automates the process of gathering IP endpoint
performance metrics and converts this data into real-time actionable information, improving the delivery of IP services. The results of our alliance will include improved user experience and a reduction in overall network operating costs.

Based on TI's digital signal processor (DSP) technology and embedded software solutions, TI's PIQUA system utilizes sophisticated, real-time calculations to instantly assess quality parameters related to the user's experience, allowing both equipment manufacturers and service providers to automatically and dynamically adapt to changing conditions and make adjustments, which today are either impossible or done manually. The integration of PIQUA software with the NetSensory Solution Insight for VoIP 2.0 from Network Physics is done via standard protocols such as RTCP-XR by communicating call quality metrics, including TI RTCP-XR extensions for reporting echo quality metrics. The NetSensory tool combines valuable endpoint information and correlates it with other network data to provide network operators and enterprise IT managers with an outstanding set of metrics for actionable and rapid
resolution, ensuring high quality services. In addition, this unique insight greatly reduces the need for further testing equipment with a real-time view into business application performance.

The NetSensory Solution Insight for VoIP overcomes problems associated with typical voice monitoring solutions by integrating standard voice quality metrics with more than 60 performance and utilization metrics. The Solution Insight for VoIP delivers real-time, integrated management of both voice and data applications from an easily-installed appliance, without the need for agents, probes, or synthetic handsets. It has the ability to drill down from industry-standard voice quality metrics to
the underlying network conditions responsible for call degradation, measure the impact of other enterprise applications on voice traffic, and judge how other applications are affected by the network changes made to support voice.

Successfully delivering VoIP and IPTV requires deep, real-time analysis of underlying network conditions that can potentially impair the delivery of these services said Kenny Frerichs, President and CEO at Network Physics. The whole point of deploying VoIP is to run voice across the network just like any other application, but voice and network management tools aren't always up to the task. The marrying of TI's PIQUA technology and the NetSensory Solution Insight for VoIP seizes the full advantage of the PIQUA system by creating a solution that optimizes services based on true end-user experiences and provides exceptional insight into application performance.
