Optimized viewer experience

Within the video player, CDN Load Balancer selects the best video source according to user device metrics, customizing delivery to each individual viewer.

Video Streaming

Maximum reliability

By dynamically choosing CDNs on a per-segment basis, CDN Load Balancer can switch CDNs during the video session without a page refresh and without adding a single point of failure to your workflow.


Enhanced QoS

An easy-to-integrate module applies a holistic policy based on your business inputs, quality of service across your user base and real-time device feedback.

Features and Specs

  • 100% transparent for end-users: no plugins or extensions to install and no page refresh required (instream switching)
  • Configurable CDN Prioritization: based on customer sensitivity to changes in video QOS
  • Instream multi-sourcing: fetching each segment from the optimal CDN for each viewer for both live and VOD streams
  • Configuration injection: per platform, per stream, tailored to each use case or subset of broadcaster’s traffic
  • Dashboard: GUI and data API for CDN traffic, bandwidth (measured by viewer devices), error rates, viewers and buffering ratio

  • Segment-by-segment decisioning to mitigate CDN failure anywhere and at any time during the session
  • Instream switching protects against the cascade effect that a CDN failure and massive wave of page refreshes can have on the video workflow
  • No single point of failure: client-side decisioning requires no persistent backend connection during the video session

  • Web: all browsers, including Chrome, Firefox, Safari, Opera, Chromium-based browsers, Edge, and IE
  • Mobile: Android, iOS
  • Connected TVs: Samsung Tizen, LG WebOS, Chromium-based set-top boxes
