Limelight: Support for Old and New Formats Crucial for CDNs

Article Featured Image

The services that content delivery networks (CDNs) are expected to provide is shifting, as a panel at the recent Streaming Forum conference in London showed, yet there's still value in supporting older video formats. Steve Miller-Jones, director of product management at Limelight Networks, explained why legacy support is critical for some broadcasters.

"The key services we've being asked to deliver from a bits-and-bytes perspective have moved over the years away from some of the legacy formats…largely toward HTTP, but there's still a range of services required across and around the world for different reasons," Miller-Jones said. "Some broadcasters, for example, have government remits which say you must support all of these legacy formats. They still buy those legacy formats and they expect those key services and that flexibility to be available from the CDNs."

That link to the past gives established CDNs an advantage.

"It's unlikely that if you're a newcomer and you fancy your hand at being a CDN you're going to support a legacy format. So I think being an established CDN with the layers and levels of customers gives us the ability to offer a wide range of key services, but it's becoming more and more focused on HTTP and HTTPS, and dealing with the security pieces and the business logic that surrounds those connections," Miller-Jones explained.
