“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.”Dan Rayburn
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.
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.

Key Improvements in Networks with
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.
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.
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.
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.
