As proof of its VideoStream claims, Cisco is citing the results of tests it commissioned from Miercom to evaluate VideoStream's performance and compare it with rival Wi-Fi products, including those from Aruba. The full Miercom report is available here. Miercom is a networking testing consultancy that is often used by vendors to validate a product's performance, sometimes in comparative testing.
Overall, according to the Miercom report, VideoStream dramatically reduced video packet loss: Without VideoStream, the packets per minute lost for five standard definition streams was 8,854 packets per minute; for five high-definition streams, the number was 89,570. When VideoStream was turned on, packet loss in both dropped to zero.
Another test measured the video delay factor, in milliseconds, for five standard definition and five high-definition streams: In the former, the delay factor dropped from 77.80 to 1.15 ms; in the latter, from 76.49 to 2.46 ms. "VideoStream optimizes the wired network performance to deliver video by using 30 times less bandwidth," Cisco's Stiff says.
Later in 2010, Cisco will introduce video features for Wi-Fi clients via its Cisco Compatibility Extensions (CCX) program. Under CCX, the company licenses to client device manufacturers Cisco code that they can incorporate to ensure that their Wi-Fi products, including adapters, notebooks, wireless VoIP phones, active RFID tags and others, work optimally with Cisco wireless networks. Stiff declined to say what those features would be or when they would be available.
