Content Delivery Networks Complicate Debate Over Network Neutrality

The network neutrality debate is often framed as a fight by everyday citizens to prevent broadband providers like AT&T and Comcast from using their servers to throttle or slow the internet traffic of business rivals. But internet service providers’ opponents in the long-running Washington fight — major content “edge” providers like Amazon, Facebook, Google and Netflix — don’t exactly have clean hands in the fight, according to analysts who say those firms have a way of favoring their content, in the form of content delivery networks.

CDNs are clusters of servers that cache data from content providers to reduce the delay before a transfer of data begins — a way for the prominent and deep-pocketed sites to load more quickly than others. The networks are often owned by third party companies like Akamai Technologies, while some of the largest content providers have built their own. Globally, 71 percent of all internet traffic will cross CDNs by 2021, compared with 52 percent in 2016. Those networks have the ability to discriminate against and interrupt content flows, according to Dan Rayburn, principal analyst at Frost & Sullivan and executive vice president of Streamingmedia. Rayburn suggested that the Open Internet Order enacted by the Federal Communications Commission in 2015 was myopically focussed on ISPs. “If you’re thinking rationally about this, you’d address it with CDNs, with transit providers, with backbone providers,” Rayburn said. “You’d address it with everybody.”
