Device and content prioritization among next steps for CDN

Device and content prioritization among next steps for CDN | Video Breakthroughs | Scoop.it

The next-generation of CDN needs to give service providers much greater control over bandwidth priorities in the home, Alcatel-Lucent believes. If there are multiple devices competing for bandwidth, you need to be able to say that a connected television needs priority for streaming and that a smartphone should be given a lower bitrate stream, for example.

 

“Service providers need a way to control the quality that is delivered to every screen and that is not possible today with adaptive bitrate streaming,” Mestric explains. “So in the CDN we will include a session manager that makes the CDN aware of all the different devices and session requests so that if you start to watch video on an iPhone and there is no congestion in the access network you will get the highest bitrate possible, but if someone else in the family turns on a connected TV device the service provider can then limit the bitrate profiles that can be accessed by the iPhone, for instance.”

 

Mestric points out that session prioritization could be useful if there is contention on mobile networks. Then a content provider could prioritize a premium subscriber over a basic subscriber so they get the higher bitrate if there is no chance to provide them both with the best possible experience.

Nicolas Weil's insight:

Interesting approach fro priviledging premium subscribers/contents, and a new competitor for Seawell Networks Spectrum which is delivering this kind of features for a long time now...

Content Delivery Networks Get Personal

Content Delivery Networks Get Personal | Video Breakthroughs | Scoop.it

Because content delivery networks (CDNs) are at the heart of next-generation IP video infrastructure, they are the logical place to add personalization. With the right approach, service providers can take advantage of the CDN replication model while delivering personalized content. At the same time, they can ensure the network scales to achieve quality expectations.

 

There are many good reasons to personalize content, including :

- Targeted ads

- Emergency alerts

- Blackouts

- Quality adjustments

 

To take control of the delivery mechanism, service providers must build a server-side version of the client-based adaptive streaming concept. Introducing two new components will bring more intelligence and processing power into the CDN to improve overall HTTP behavior and performance:

A session manager retrieves the contextual information needed to customize the content and tell the cache in the CDN which changes to apply to the content.A video processor in the cache generates the new content to be sent to end users based on the original content and the information delivered by the session manager.
