Surge in OTT traffic highlights importance of CDN infrastructure

For streaming of live events such as the 2018 FIFA World Cup on OTT services, TV delivery networks have to be equipped with a scalable content delivery network (CDN) workflow to manage peaks in their streaming traffic, suggests Edgeware

Edgeware has reported that many of its customers have experienced a doubling of their peak CDN streaming traffic on match days during the 2018 FIFA World Cup football tournament.

According to the company’s analytics data, major cultural and sports events like the World Cup create “sudden surges” in demand on over-the-top (OTT) services, bringing forth the importance for media service providers to have their infrastructure readily in place to manage events of such scale.

Edgeware also reported that over half of all streaming requests happen within the first two minutes of a popular event, placing strain when onboarding viewers onto any delivery network. And with social media playing an increasingly active role when watching live programming, any unwanted buffering can create a delay stream which can impact the overall viewing experience.

Calling events like the World Cup “big live” OTT, Johan Bolin, vice-president of products at Edgeware, commented: “As our data shows, peak demand on our customers’ TV CDNs has typically doubled every match day during the tournament. And as we see more and more broadcasters turning to OTT to create a new ‘beyond broadcast’ services, such as 4K/Ultra HD (UHD) and virtual reality, it has never been more important to have the right infrastructure in place.”

With an aim to take OTT and IPTV services beyond broadcast, Edgeware has equipped its TV CDN solution with the ability to predict increases in user sessions, so that the expected load can be balanced across the network’s servers. Besides reducing the risk of congestion, the TV CDN solution is also capable of consolidating requests between the delivery server and content owner’s origin, thus reducing peak demands, Edgeware added.
