The CDN Federation: Spreading Benefits Across the Web-Video Value Chain
Whether driven by live sports or blockbuster movies, the explosive demand for Internet video keeps rising. Indeed, by 2015, Cisco projects a quadrupling of IP traffic, 90 percent of which will be video.
This is an exciting trend. But headaches abound, up and down the value chain. One solution is the CDN federation, which Cisco IBSG is exploring in a three-phase pilot program. In these alliances, content delivery networks owned and operated by service providers would interconnect—and leverage—one another’s resources.
CDN federations would benefit all players:
- Consumers gain in quality of service, since the closer the cache is to the end user, the faster the response time. Also, a multitude of interconnected CDNs and content providers promises a much wider variety of content.
- SPs can increase revenue by offering a better value proposition to content providers. Pooling data across separate CDNs lessens the overall burden on the network, especially as mobile devices proliferate.
- Content providers will be assured that their offerings—in particular, paid content—will be distributed with guaranteed service and to a wider, potentially global audience.
