THIS INTELLIGENT OPTIMIZATION IS MADE POSSIBLE BY A NUMBER OF TECHNIQUES:
• Static server-side geo rules: transit lines and CDN providers have variable level of quality
of service in different regions of the world. While some of them may work well in the US
they may perform less well in Asia or Europe and vice versa. Ustream has a global, up-to-date picture of their performance and uses this information to make optimal decisions
on a per user basis.
• Real-time client-side quality module: while the playback client will start with the
predictably optimal cost / quality choice of delivery method it is possible that the
preselected source may have quality issues during playback. To mitigate this the client
continuously monitors quality-related performance metrics, and in case of QOS issues
seamlessly switches over to the next available stream source.
• Real-time server-side quality module (beta): the next evolutionary phase of the client-side switching module, the server-side quality module keeps a tally of QOS reports
coming in from playback clients per provider and AS number uses this information to
predictively keep new clients from using a problematic provider-AS pair in case there are
repeating issues detected on that pair.
ULTIMATE SCALE WITH OPTIMAL QUALITY
The Ustream platform was built with the goal of being able to scale effectively for massive global events, while
maintaining the highest quality viewing experience on any device.
The platform leverages a diverse pool of CDNs to ensure an uninterrupted viewer experience and offers live
cloud transcoding of video. It’s capability to handle over a million concurrent viewers on a single broadcast
