Cedexis adds on-device video metrics to load balancing tools

CDN load balancing specialist Cedexis is starting to make more of a case for itself purely in video and not just as a management tool for generic CDNs. This week at NAB it took another step towards video analytics by announcing availability of a version of its CDN load balancing which is powered partly from its global view of how well respective CDNs are performing in real time, but also from its own Quality of Service (QoS) metrics collected on a given publisher’s customer devices.

The company also announced a partnership with Qwilt, the open cache video specialists, so that it can also get QoE video data from the Qwilt network of open cache deployments, deeply embedded in global ISP networks

At present this is a subtle shift from purely monitoring how well CDNs are performing to monitoring how video is performing in your device in an HTML 5.0 browser, using a piece of downloaded Javascript.

This deal with Qwilt opens up the control, not just over CDNs, but over any video processing node, be it open cache, CDN or cloud instance, which video is running on. Later Cedexis hopes to partner with pure play analytics players such as Conviva, and use those analytics to affect node selection in real time.

We spoke to Simon Jones, marketing leader at Cedexis, who told us that the company was able to report on device bit rate and video buffering events using Javascript tags on remote devices

“We don’t pretend our analytics have the depth of Conviva’s software – but it’s free and we make this data available to our OpenMix app which controls which CDN you are connected to.

At present, it only runs as Javascript in the browser so it cannot report on operator video which is app based, but this is coming. “We can’t report on Flash or Silverlight, but we are adding platforms as fast as we can,” said Jones.

“We hope to fuse this data with other data sources like New Relic and Akamai and our expectation as we look forward is to integrate with other analytics players such as Conviva and Nice People at Work. We think this will be particularly important at Live events.”

“Increasingly we are not just talking about balancing CDNs, but any node which is serving video like an Open Cache ISP server like Qwilt and virtual pops, and slowly we plan to come out with products which are more and more video specific,” said Jones.

The Cedexis Radar community currently tracks the status of Internet delivery through 10 billion real user measurements every day. This data is then used by the Openmix global server load balancer to make real-time predictive traffic routing decisions.
