Presentation

Check out one of the latest presentations about Open Caching.

Watch the fascinating panel discussion between Jonathan Candee, CCO at Qwilt, Sanjay Mishra, Associate Fellow at Verizon, and Michael Fay, former SVP of Media Distribution and Infrastructure at Disney Streaming.

Together, they delve into the content distribution value chain and, importantly, the growing role of Open Caching within it. They also explore several real-world Open Caching use cases, along with results that show the impact it’s having in improving the quality of experience for viewers.

The Components Of An

Open Caching Network

The architectural diagram above describes the flow of traffic through Open Caches in an Open Caching Network, illustrating the interoperability between Content Owner, ISP, and CDN. Driving that interoperability are the core components, connected through APIs, which enable the fundamental capabilities to mange delivery, caching, logging, and more.

Open Caching Technical Specifications

The SVTA’s Open Caching is a series of functional requirements and specifications. The functional requirements define the network architecture and functionality, while the specifications define the functionality through API operation. The SVTA LABS initiative then codifies the specifications into working reference code. All of the functional requirements and specifications can be found below. They are available free to the public.
