QoSmetrics Upgrades Tester
CAMARILLO, Calif. --QoSmetrics, a leading provider of network performance assurance hardware and software solutions for triple play networks, has upgraded its V-Factor technology for Internet-Protocol-TV (IPTV) performance assurance capabilities to now include audio performance assurance alongside streaming video performance assurance. With audio capabilities offered for the first time, carriers / service providers can assure audio and video perform as expected. The largest advantage is that these capabilities are possible from a service provider's core network, but with the insight as to how a user actually perceives video and audio quality at their end -- as if the service provider were assessing quality from in front of a user's TV set. Enhancements have also been made to V-Factor to allow service providers to segment IPTV video and audio performance assurance by channel, geographic region and various other segmentations for greater isolation of service impairments. The combination of allowing performance assurance of video and now audio from the core but with insight as to how a user is actually perceiving quality is a breakthrough capability for service providers seeking to ensure growing IPTV adoption rates by consumers.
QoSmetrics was first to market with V-Factor as a next generation technology that standardizes video quality performance assurance when first made available in April 2005. The company is now also first to market to combine video with audio performance quality assurance in a single technology for next generation IP-based video services. The audio quality is measured using the well understood and accepted MOS and R-Factor models that are widely used for assessing Voice-over-IP (VoIP) quality. V-Factor technology consists of an algorithm and methodology that when used maximizes video quality -- and now audio quality -- through the entire chain of delivery right down to the end user. V-Factor removes previous limitations of relying on assessments that only inferred quality by delivering the first true technology that provides specific delay, loss and jitter metrics with pinpoint accuracy to network performance impairments.
QoSmetrics V-Factor-enabled products are being tested by select unnamed carriers and services providers in Europe and Asia. V-Factor upgrades that include audio capabilities are available now from QoSmetrics for existing customers and will be shipped as part of new product purchases immediately. The latest software release provides a new microcode for QoSmetrics NetWarrior hardware probes that will provide real time video and audio streaming decoding and video and audio quality monitoring. This new addition provides, as with previous products, Internet Protocol (IP) Service Level Agreement (SLA) metrics such as delay, loss and jitter based on the International Telecommunications Union (ITU) standard Y1540/1. It also provides metrics for Voice-over-IP (VoIP) such as Mean Opinion Score (MOS) capabilities based on ITU G107 and Video-over-IP metrics based on QoSmetrics' V-Factor and European Telecommunications Standards Institute (ETSI) TR101290 metrics, as well as other Key Performance Indicators (KPI).
Network engineering management and quality assurance management at carriers, service providers and large enterprises that are deploying voice and video applications such as IPTV and triple play (data, voice and video) applications are prime customers for QoSmetrics' newly upgraded products. Aggregation points such as a Point of Presence (POP) that connects a DSL Access Multiplexer (DSLAM) device to the multicast network are good candidates for V-Factor use. The V-Factor microcode resides in NetWarrior, QoSmetrics hardware probe, but V-Factor can also be ported to other network appliances such as a setup box.
"By enabling audio performance assurance alongside video quality assurance, and with pinpoint accuracy to network impairments, we are setting a benchmark for how to cost-effectively measure and assure performance of digitized streaming AV applications in the delivery of next generation services such as IPTV," said Yves Cognet, Chairman of QoSmetrics. "We now offer service providers a cost-effective solution that lets them test and assure video and audio quality in real time with the same degree of accuracy that they test and assure voice and data network performance. We help them in their challenges of meeting tough SLA agreements and therefore assuring themselves of greater revenue from satisfied customers."
