Streaming Video Alliance Announces New Open Caching Technical Specification and First Open Source API Developed in LABS

Newly Approved Specification Reflects Ongoing Contributions of Alliance Working Groups to Solve Industry-wide Issues


FREMONT, Calif. — July 1, 2020The Streaming Video Alliance (the Alliance), a global technical association developing solutions to address critical technical challenges in delivering a high-quality video experience at scale, today announced the immediate availability of a new technical specification document from the Open Caching Working Group. The Open Caching Relayed Token Authentication document, recently ratified by the Alliance membership, describes the functional specification of open-caching relayed-token-authentication mechanism and focuses on generically supporting URI signing using this method.


“Delivering public specifications to the market is one of the Alliance’s top priorities and most valuable contributions. This document was a considerable effort by the Open Caching Working Group, and is another example of the tremendous value our members are bringing to the industry,” said Jason Thibeault, Executive Director at the Alliance. “In addition to the new specification announced today, the QoE Working Group is making good progress with the Best Practices for End-To-End Workflow Monitoring document which passed the first round of ballots and will be moving into the second phase of the voting process.”


LABS Enables Industry to Build Next-Generation Streaming Services; Develops New API

The Alliance’s open source initiative, LABS (, develops next-generation open source code for the streaming video industry and is focused on projects that bring Alliance specifications to life. LABS furthers the Alliance Working Group lifecycle from defining an idea or challenge to developing and publishing a solution to, now, codifying the solution in the form of reference code. Member companies can contribute resources for developing open source software based on the Alliance’s published specifications.


The Capacity API is the first project developed in LABS and is currently in review with the group. It is intended to allow participants in the federated video delivery service to communicate availability and capacity information as needed. The design is meant to encompass multiple use cases, including one content provider to many CDNs/ISPs as well as more complex multiparty interactions, all while preserving the flexibility and business models of the underlying providers. More details can be found here:


Recently completed in LABS is the GEO-Data for IPv6 JSON schema. There are many different approaches to associating attributes to an IP address and many different attributes that can apply. There are also several different approaches to delivering that data. This document focuses on attributes that fall into three categories: Identity, Service, and Location. It provides a JSON object model and schema to represent how those attributes can be tied to an IP address in a common format for controlling the access to streaming video using geo-location data for IPv4 and IPv6 addressing.
