Open Caching

What if ISP subscribers could stream content from local caches rather than back-hauling from peered networks or over the public Internet?
Now they can.

Streaming Video Alliance logo

The Streaming Video Alliance provides a forum for collaboration to improve interoperability among operators, providers, and vendors. Together, companies from across the video ecosystem work to build best practices and specifications that ensure a more consistent end-user experience and promote further adoption of online video. Among the initiatives pursued by the Alliance is Open Caching which enables cable, telco and mobile network service providers to cache and deliver streaming media from deep inside their networks and much closer to consumers. Qwilt has been a leader in the development of Open Caching specifications since the formation of the Alliance.

“Nearly every major telco, MSO, and mobile operator is actively looking at or deploying some kind of open caching technology today. It is a required element in their network to control OTT video content consumption and to provide the best possible end-to-end user experience. It is a unique technology that simultaneously benefits a content owner, a network operator, and, most importantly, a broadband or wireless subscriber.”

Streaming Video Alliance Open Caching

Qwilt is proud to be the Co-Chair of the Open Caching Working Group within the Streaming Video Alliance - driving forward the architecture that powers the internet for years to come.

Qwilt Content Delivery Sharing and Qwilt's Open Edge Cloud are fully compliant with Streaming Video Alliance Open Caching specifications.


Overview

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.

Objectives

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

How Open Caching Works


Key Improvements in Networks with
Open Caching

REDUCED BANDWIDTH COSTS

Open caching minimizes the number of times video titles are delivered from the content provider sites, which substantially reduces the total volume of data crossing the transit links. Popular, frequently viewed videos are identified, stored, and delivered to subscribers from within the network.

ROBUST NETWORK

As the overall volume of OTT video traffic traversing the service provider network decreases, network conditions improve dramatically even during peak consumption periods. This improves performance for all other bandwidth-sensitive non-cacheable network traffic, applications, and services, and non-cached video content.

INFRASTRUCTURE SAVINGS

Operators can achieve substantial CAPEX savings by drastically reducing the amount of infrastructure investment needed to support the rapid growth in bandwidth demand. By leveraging open caching for video delivery, service providers can prepare their networks for the future of online video.

OPTIMAL QOE

Operators can ensure a quality, immersive experience every time by delivering video from close proximity to the subscriber. With an open caching solution, high quality video is always delivered in the original content provider fidelity, without the pesky disruptions, lengthy download times, and control response delays.
