Intelligent Caching In An ABR Multi-Format CDN World (2012)

By Patrick Wright-Riley, Brian Tarbox, Motorola Mobility, Inc.

In their infancy, content libraries contained a few thousand pieces of content and most vendors put a copy of everything everywhere. As the contents grew to tens of thousands of titles, Central Libraries were added and Least Recently Used (LRU), then intelligent caching, was employed. As content libraries have grown by orders of magnitude and now adding Adaptive Bit Rate/multi-format copies to the mix, some suggest intelligent caching is no longer possible. Motorola asserts that intelligent caching is both possible and even more critical today than ever. Intelligent caching still plays a valuable role in the ABR Multi-Format world.
