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
