Collapsed Cooperative Video Cache for Content Distribution Networks

Edison IshikawaCláudio Luis Amorim

In this work we describe the Collapsed Cooperative Video Cache (C-CVC), a novel scalable technique for delivering video streams over content distribution networks (CDNs). C-CVC is based on the idea of collapsing client buffers into the proxy caches on the CDN edges nearest to the clients while enforcing transparently cooperation among clients that share the same video content. As a result of storing videos close to the clients, C-CVC decreases the average initial video exhibition latency. C-CVC also reserves cache space in the proxy, therefore absorbing more jitter and using less CDN resources. Most importantly, by implementing the collapsed cooperative video cache globally across CDN's proxies, C-CVC enables VoD systems to become highly scalable.
