FREMONT, CA — (Marketwired) — 04/28/15 — The (SVA), a newly formed industry forum comprised of leading companies from the online video ecosystem, has today 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.
As online video continues to undergo tremendous growth, the underlying streaming video infrastructure must scale quickly, efficiently and cost effectively to meet consumer demand. Achieving success in streaming video relies heavily on creating an open architecture infrastructure model that fosters broad collaboration throughout the online video ecosystem. The SVA has made this its mission; the organization plans to develop, publish and promote open standards, policies and best practices that allow the online video streaming ecosystem to flourish.
Today–s Internet architecture does not support efficient, large-scale deployment of video services across all components of the delivery infrastructure. Incentives between compute, storage and network have not been optimized as part of a unified delivery system. Industry collaboration across the streaming ecosystem is necessary to quickly address this need and establish the architecture required to scale online video.
With this framing in mind, 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:
– Components of the system can be implemented by anyone
The system can serve any content provider stream, including HTTP, HTTPS or other delivery protocols
– The system optimizes the use of storage and compute resources for many content providers
– Content is treated objectively and in real time
The system creates alternate network capacity and reduces congestion within the ISP network as well as reduces server capacity requirements for the content provider
– Components of the system can run as a software solution
– The QoE for end users being served by the Open Cache will meet or exceed the current QoE without the Open Cache in place.
Open caching offers clear benefits for the entire video ecosystem. Open caches, geographically distributed at the subscriber edge of ISP networks and implementing the guiding principles outlined in this document, can create an aggregate scale of compute and storage resources that complements, extends and enhances that of any individual CDN. Open caches offload large volumes of streaming traffic from both CDNs as well as the peering and aggregation path inside ISP networks, in network nodes where CDN-only caching systems could not efficiently or economically operate.
By using open caching and serving the majority of popular video content from within the ISP network, operators will dramatically improve the end user experience by eliminating or reducing potential congestion points in the network and enabling the network to scale efficiently to meet online video demand.

Founded in 2014, the Streaming Video Alliance–s (SVA) charter is to encourage deeper collaboration across the entire online video ecosystem, which will include the development of standards, best practices and policy for an open architecture that will span the entire online video value chain. The SVA is currently focused on identifying issues and solutions related to open architecture, quality of experience and interoperability. For more information, please visit .
