Abstract: Systems and methods for streaming of multimedia files over a network are described. A streaming delivery accelerator (SDA) caches content from a content provider and streams the cached content to a user. Cached content is incrementally added to the cache memory, and the SDA is disconnected from the content provider when sufficient content for a predetermined time of play has been received. The caching process can be iterative, with only content not previously retained in the cache requested from the content provider. A method for cache eviction of content no longer of interest to users is also described.

Abstract: Systems and methods for streaming of multimedia files over a network are described. A streaming delivery accelerator (SDA) receives content from a content provider, caches at least part of the content, forming a cache file, and streams the cache file to a user. The described systems and methods are directed to separate (shred) the content into contiguous cache files suitable for streaming. The shredded cache files may have different transmission bit rates and/or different content, such as audio, text, etc. Checksums can migrate from the content file to the shredded cache files and between different network protocols without the need for recomputing the checksums.
