Qwilt Enables Transparent Caching for Live Video Streaming

Qwilt, a start-up based in Redwood City, California, introduced a  transparent caching solution for live-streamed events online.

The Qwilt Live Stream Cache, which is a software upgrade for the company's QB-Series Video Fabric Controllers, detects trending and popular live OTT video streams, enabling the QB-Series to instantly direct those streams into the controller's FastCache, a dedicated control and storage path optimized for quick delivery of live streams. The Qwilt Live Stream Cache then establishes a local live video transmission point in each neighborhood that can serve a very large population of nearby subscribers using a single seed stream, offloading significant strain on operator network infrastructures.

Qwilt's QB-Series Video Fabric Controllers are deployed by cable operators and broadband carriers close to subscribers, typically next to a B-RAS or CMTS.  The company says its solution can deliver a 50% reduction in traffic while improving average video bit rates during times of peak network utilization. The QB-Series Video Fabric controller is 100% software running on COTS. A 2U form factor offers 10 Gbps of video delivery capability, 20 Gbps of analysis, and 20 TB of onboard storage.

Qwilt said this innovation will prove especially effective for live event, such as the Super Bowl, Olympics or World Cup, as

"High quality live event streaming is the 'holy grail' of online video. However, until now, the required infrastructure from the origin server, through CDN, via operator last mile network, was not designed to deal with the scale and capacity required to deliver a high quality experience to the consumers. As consumers increasingly look to access live and VOD content from connected devices, network operators and content providers must keep pace with demand," said Alon Maor, CEO and Co-Founder of Qwilt.

  • Qwilt was founded in 2010 and is backed by over $40 million in funding from Accel Partners, Bessemer Venture Partners, Marker and Redpoint Ventures.
