Akamai, Juniper team on elastic CDN

DetailsMichelle Clancy | 17 October 2014

Akamai Technologies and Juniper Networks are teaming on an elastic content delivery network (CDN) system, which is designed to enable network operators to address network scalability challenges driven by the rapid increase in video traffic.

The two have a proof-of-concept demonstration that will leverage Akamai's virtualised Aura Licensed CDN (LCDN) software and Juniper Networks' Contrail Controller for software-defined networking (SDN) and network function virtualisation (NFV).

The solution is aimed at supporting the broadcast of large events along with multiscreen video services.

Video consumption has shifted dramatically from a relatively predictive and controlled model to one that is highly dynamic, driven by large traffic spikes during online live and on-demand events. Streaming large live events and popular on-demand titles can cause significant network congestion that leads to a poor subscriber experience, brand erosion and customer turnover.

Unlike previous approaches which required dedicated hardware and extensive planning to add capacity, the elastic CDN solution runs on virtualisation platforms, and is highly distributed and virtually networked to enable efficient use of resources.

"Content delivery networks are evolving to meet the needs of increasingly real-time, distributed applications and users," said Jennifer Lin, senior director product management at Juniper Networks. "Overlay networks have proven to simplify and automate the delivery of application and user-centric services without the administrative overhead of traditional infrastructure approaches. By combining Akamai's virtualised caching components with Contrail's scale-out network service automation, the companies have created a truly elastic CDN solution to meet the emerging needs of telco clouds."
