Overview

Mission

As the amount of online video increases, ISPs face a challenge—the burdening of their networks with a growing amount of Internet-sourced traffic such as online video. But what if the ISP could pull video content from local cache? In this working group, participating members focus on helping ISPs solve this traffic problem by establishing the underlying technical and functional requirements for implementing an in-network, open caching system.

To create the functional and technical requirements for open caching systems inside ISP networks

Objectives

Documents

The Streaming Video Alliance Open Caching Working Group has two objectives. First, to identify the critical components of a non-proprietary caching system; and second, to establish basic architectural guidelines for implementation of an open caching system.

The documents below are listed in chronological order.

Open Cache System Functional Requirements

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 Cache Request Routing Technical 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 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 Service Provisioning 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 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.

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.

Optimizing Video Delivery with the Open Caching Network

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.
