I want my CDN

As consumers, we are obsessed with newer, bigger and thinner displays, 4K and HDR innovations, and now even virtual reality goggles. We demand an outstanding viewing experience across all our latest “toys.” Traditional broadcast television has set a very high bar in this regard. Broadcasters know they must now provide a similar experience on every device in order to attract and retain audiences.


Sky, in the UK, continues to exceed customer expectations, and has deployed the Nokia Velocix CDN (Content Delivery Network) to assure a better viewing experience for its millions of on-demand subscribers.

In 2010, Sky launched its TV on demand service. The ensuing popularity of the service resulted in unprecedented traffic growth. Growth that strained delivery resources, provided by a major global services CDN provider, and drove up costs in line with increasing service adoption. Sky sought increased control over the delivery platform and wanted to prioritize a few key challenges, including improved visibility into viewing patterns, content usage and system issues. Nokia’s CDN allows Sky to manage delivery more effectively, increase performance and uphold its commitment to an outstanding customer experience.

Sky is not unique in this regard.

Historically many broadcasters have used global services CDN’s to enable their over-the-top (OTT) services. While this meant a short time to market and an immediate global presence, it was also fraught with high service costs and lack of control. Broadcasters are now beginning to re-evaluate this model.

While licensed CDN deployments have long been limited to big OTT companies and network operators, many broadcasters are also contemplating deploying their own CDNs. These can be based on open source technology, but the majority are considering CDN technology from a specialized vendor like Nokia. For Sky, the Velocix CDN provided better overall performance, faster time to market and an array of sophisticated features for service optimization, monitoring and management not available in open source deployments.

A successful deployment also meant that Sky needed to seamlessly augment its third- party CDN service. There could be no customer impact, or service interruption. This was another key factor in the selection of Nokia. The Velocix CDN seamlessly provided support for an open dual vendor strategy, while the Velocix Proxy Language enabled the re-use of established delivery workflows. These attributes helped reduce the time, cost and complexity required to integrate and deploy the platform.

It’s clear that Sky is the first of a long line of savvy broadcasters who will deploy their own CDN. This means that it won’t be long before we can all have an outstanding experience on our various new devices.
