Device and content prioritization among next steps for CDN

Device and content prioritization among next steps for CDN | CDN 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.

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...

Marché CDN 2012 : Activité intense pour Akamai

Marché CDN 2012 : Activité intense pour Akamai | CDN Breakthroughs | Scoop.it

Cette année a été bien occupée pour Akamai, sur un marché du CDN très dynamique. On pouvait se demander en début d’année 2012 si ce marché, avec l’arrivée des CDNs d’opérateurs et des fédérations de CDN n’allait pas se “commoditiser”. Il semble que ce ne soit pas le cas et Akamai, leader sur ce secteur, prend la voie de la différentiation, sur la vidéo et la QoE en particulier. La société le démontre au travers de plusieurs acquisitions et actions très marquantes cette année.

Broadpeak Introduces umbrellaCDN, Advanced CDN Selection Solution [PR]

Broadpeak Introduces umbrellaCDN, Advanced CDN Selection Solution [PR] | CDN Breakthroughs | Scoop.it

Broadpeak today launched umbrellaCDN™, an innovative solution that offers content providers and pay-TV operators complete control over the allocation of video content to multiple CDNs. Utilizing umbrellaCDN, users can select the best CDN for live or VOD content at all times — according to various criteria — enabling them to provide the best possible quality of experience for end-users at the best possible cost.

 

Content providers can create parameter-based rules according to a wide range of criteria, including end-user geo-location, end-user ISP, type of content (e.g., live or VOD, pay or free, premium or trailer), and time of day or day of the week. Rules are managed through three distinct modes: quality of service, where the chosen CDN is the one that offers the best quality in a given region; load balancing, whereby sessions are divided between several CDNs; and quotas, with a maximum number of sessions allocated to each CDN.
