Qwilt's transparent caching solution was recently featured in a Frost & Sullivan report, "Video QoE 2012: Managing the Video Tidal Wave for Quality & Profit", for its innovative approach to network video bandwidth and subscriber QoE optimization with a unified, feature-rich, turnkey transparent caching platform.
Units feature an 8 MHz video bandwidth and 10 dB optical budget for applications where the distance is less than 2 miles.
The fully integrated solution combines Fujitsu's leading Primergy Servers and XG Series 10GbE Switches, Myricom's Myri-10G 10-Gigabit Ethernet network adapter cards with new VideoPump(TM) specialized video-streaming software, and Broadcast International's CodecSys(TM), a breakthrough, multi-codec video compression technology that cuts video bandwidth requirements.
The solution enables this operator to realize significant savings by dramatically reducing optimizable video bandwidth by up to 40% and overall bandwidth savings of up to 20%, while maintaining a high customer QoE.
CodecSys' patented, breakthrough, multi-codec compression software cuts video bandwidth requirements over satellite, cable, IP and wireless networks to enable a new generation of applications such as streaming video to computers and mobile devices.
