摘要

Embodiments of the present invention are directed to a system and apparatus for tracking media content (storage) and its cache (that is synched with the original content) in a large-scale wide-area distributed network. The system includes at least one mini tracker which is configured to keep information on the location of the content and to distribute this information to micro trackers in a first jurisdiction. The system also includes at least one zone tracker which is configured to keep information on the location of the content in a region and to distribute this information to mini trackers in a second jurisdiction. The system further includes a master tracker which is configured to keep information on the location of the content in all regions in a third jurisdiction to distribute this information to zone trackers in the third jurisdiction. The micro tracker (in wired or mobile end device/point) is configured to obtain location information from at least one of the mini tracker or zone tracker if a primary source malfunctions.
