Open Cache Logging Requirements Specification
This includes the Open Caching System (OCS) technical specifications for logging data to help track data acquisition and the delivery of it to the end user.
Open Cache Request Routing Functional Specification
High-level functional specification of open caching request routing and the required interfaces to enable request routing to be performed from an upstream CDN to an open cache system.
Open Cache Request Routing Service Provisioning Interface Specification
This includes the functional specification of open-caching service provisioning interfaces enabling a CDN and an SP to exchange information to enable the delegation of CDN content requests to the SP Open Caching system.
Open Cache Solution Functional Requirements Document
Problem statement and functional requirements of an open caching solution deployed by service providers to be used by content providers and content delivery networks.
Open Caching Content Management Operations Specification
This document describes the functional specification of the Open Caching Content Management interface and the functionality requirements from the SP Open Caching system. This document discusses the interface between the SP Open Caching Controller and the CDN. The interface between the SP OCC and the cache nodes (OCNs) is beyond the scope of this document.
Open Caching Logging Integration Functional Specification
This document describes the process of provisioning a Logging Integration between a CDN and an ISP in an Open Caching solution. That is the process of configuring how delivery logs are transferred from ISP to CDN. The requirements for logging in Open Caching Nodes are described in the “Open Caching Logging Requirements Specification” document. This document defines extensions to the “Footprint and Capabilities” interface and to the “Service Metadata” interface, to allow provisioning a Logging Integration.
Optimizing Video Delivery With The Open Caching Network
Delivering a great video experience requires content to be served as close to the end-user as possible. In this whitepaper, we illustrate how network operators can implement Open Caching nodes at the edge of their network, while adhering to specifications created by the Open Caching Working Group of the Streaming Video Alliance. These nodes can mitigate delivery latency and provide an improved viewer experience when hosted by the ISP and connected to the CDN/Content Provider nodes outside of the operator network, to create an Open Caching Network.
Open Caching Relayed Token Authentication
This document describes the functional specification of open-caching relayed-token-authentication mechanism. The focus is on generically supporting URI signing using this method. There are additional applications – like user Cookies, which are mentioned in this document without getting into the specifics. While multiple different CDNs, as well as CDNi, support Tokenization in alternative methods, the goal of this implementation is to support all of these different formats via the relay authentication mechanism.

Open Cache Request Routing Functional Specification (Version 2.0)
This document describes the high-level functional specification of open caching request routing and the required interfaces to enable request routing to be performed from an upstream CDN to an open cache system. This version has been updated to address the Manifest Rewrite routing scheme.
Open Caching Capacity Interface
This document defines the specification for an API to retrieve capacity metrics from an Open Caching Node.
Open Caching Performance Measurement Specification
This document outlines measurement metrics for open-caching. The focus of this document is to outline key performance indicators related to quality of service metrics at the open cache nodes that is responsible for delivering the streaming content.
