“Mirror segmentation”: A New Segmentation Strategy for Video Objects inside Video Caches

Multiple strategies for caching video objects have been proposed in recent years in order to maximize byte-hit ratio and better cope with large sizes of video objects. Usually, a video proxy-cache will use the same strategy when caching all its objects. We propose a new approach, which enables a proxy-cache to decide which strategy to use on a per object basis. In this context we introduce a new segment-based strategy called “mirror segmentation” which is to be deployed only for select objects, depending on clients’ access patterns. Some initial measurements regarding the new segmentation strategy’s performance using byte-hit ratio as a metric are also presented as well as comparisons with other caching strategies.
