Distributed storage approach in content delivery networks

This paper describes an approach that improves the functionality of LH*RS - high-availability scalable distributed data structure. The core concept behind this approach is the particular implementation of LH* schema that allows efficient imagery data storage for content delivery networks (CDN) to be created. We propose the novel wavelet-based method of buckets composition and distribution among storage nodes to improve the basic characteristics of schema. This method is less redundant than image pyramid structure (MIP maps). Also we propose some ideas for multilevel encoding algorithms and multilevel privacy protection in this storage schema.
