Open Caching Can Improve Streaming Video Delivery for Everyone
OTT operators, CDNs, ISPs, and everyone involved in streaming can benefit by embracing Open Caching.
The Face of Streaming
Note: the statistics regarding CDNs used and time spent purging was collected from SVA member companies through an internal survey. The results are not statistically valid.

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.
Caching Node
An Open Caching Node represents a caching server, within a content delivery architecture, that complies with Open Caching specifications. The cache can either be built using the specifications (such as for an ISP implementing Open Caching at the edge of their network), or Open Caching functionality can be added through plugins or other means (such as for a Content Delivery Network caches or OTT Platform origins).
Request Router
The Request Router handles the inbound request for content and forwards this request to the appropriate caching node within an environment. The Open Caching specifications identify three methods of routing: DNS, HTTP, and Manifest.
Control Plane
The Control Plane handles all communication related to management of configurations, content purging and pre-positioning, logging, and security. While the Request workflow is focused on the end user’s ability to retrieve content, the Control Plane is focused on how the different members of the video distribution chain are empowered to partake in the delivery process.
Open Caching Technical Specifications
The SVA’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 SVA 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.
