SVA Published Open Cache Guiding Principles

The Streaming Video Alliance (SVA) published "..guiding principles and system attributes from its Open Caching Working Group. The SVA was established to create an open architecture, standards and best practices to support the future of online video"

SVA member list includes vendors such as Alcatel-Lucent, Cisco and Qwilt [see "Qwilt: "Open Transparent Caching" vs. Content Providers' "Black Boxes""- hereas well as CSP such as Comcast, KT, Telecom Italia and Telstra. However,major OTT VIdeo providers such as Netflix are not there.
"..  the Streaming Video Alliance has commissioned the Open Caching Working Group to develop proposed standards, best practices and policy to support a new layer of content caching within the ISP network, close to consumers. 

The Open Caching Working Group, commissioned earlier this year, has already developed a guiding principles document which will serve as the basis for a proposed Open Caching specification. This new Open Caching layer will perform a network function, optimizing network capacity utilization and quality of experience. Moreover, the Open Caching Layer will be open and universal, able to optimize any HTTP, HTTPS or other delivery protocols from any provider.

The attributes of Open Caching system include:
  • Open - Components of the system can be implemented by anyone
  • Universal - The system can serve any content provider stream, including HTTP, HTTPS or other delivery protocols
  • Shared Resource - The system optimizes the use of storage and compute resources for many content providers
  • Fairness - Content is treated objectively and in real time
  • Network Function - The system creates alternate network capacity and reduces congestion within the ISP network as well as reduces server capacity requirements for the content provider
  • Software-based - Components of the system can run as a software solution
  • Quality of Experience (QoE) - The QoE for end users being served by the Open Cache will meet or exceed the current QoE without the Open Cache in place.
