Internet service providers (ISPs) get a lot more attention than any of the other players in the streaming video space. But there's another piece of the video ecosystem that is becoming absolutely critical to how content on streaming sites like Netflix finds its way to people's TVs: Content Distribution Networks (CDNs).
A new report from BI Intelligence on the video ecosystem finds that CDNs specialize in delivering large volumes of traffic over multiple ISPs, varying geographies, and piping it through internet infrastructure. In short, CDNs take the guess-work and heavy lifting out of the complex task of delivering video, in a reliable manner, to millions of viewers served by a variety of different ISPs.
Now, content providers like Netflix and Google are continuing to build out their own CDN networks — Netflix Open Connect and Google Global Cache, respectively — to better deliver content to consumers and attain more control over how their traffic is routed.
Netflix Open Connect already accounts for 13% of CDN traffic as of 2013.
Purpose-built CDNs like Open Connect give streaming video services greater control over the performance and cost of content delivery. Just like third-party CDNs, content provider-run CDNs must also establish relationships with other network operators.
Netflix would not have had to establish its individual paid interconnect agreement with Comcast, if it had continued to use a third-party CDN service instead of Open Connect.
