Shenick Network Systems, a provider of per-flow IP communications test and monitoring systems, says that its diversifEye per-flow architecture has been selected by SeaChange International as the only test product to provide “a uniquely flexible platform to emulate and measure each individual video-on-demand client behind residential gateways.” The company says that diversifEye will allow SeaChange’s telco and cable operator customers to quantify the quality of experience (QoE) of every on-demand video watched by their subscribers.

According to Shenick, diversifEye enables complete functional and scalability testing of VOD delivery architecture for customers of SeaChange’s Axiom On Demand open content delivery platform. The technology is billed as simulating set-top boxes with VOD real-time streaming protocol (RTSP) clients that are compliant with SeaChange video servers. It enables SeaChange customers to perform stateful, functional and scalability testing of both the control plane and media plane architecture of the VOD solution, the company says, and also to quantify the effect of mixed traffic environments on the quality of video flows, up to thousands of users at 10 Gigabit Ethernet levels. “We moved from VOD being used by early adopters to becoming a mainstream application used in tens of millions of homes, and the challenge faced by service providers is that consumers have set an extremely high threshold level for the expected quality of video flows: even one customer disrupted is one customer too many,” Robert Winters, chief marketing officer at Shenick, said in a prepared statement. “It is not sufficient for a service provider to measure aggregate service quality in their pre-deployment tests; it’s become necessary to be able to quantify the quality of the video offering for each subscriber. Shenick’s diversifEye can help triple-play providers to view individual subscriber service quality on a highly granular basis.”

Shenick bills diversifEye as enabling both active and passive analysis: passive analysis applies real-time analysis to any video stream; active analysis, in addition, compares the source media stream and the subscriber-received stream for discrepancies. In addition, the company says, its per-flow architecture enables very granular control of signaling processes and granular per-flow measurement capability–meaning that each individual entity can be concurrently configured, controlled and measured.
