Abstract

An edge node (33), a parent node (32), and a method in a Content Delivery Network (CDN) (30) configured to utilize adaptive streaming to deliver a piece of electronic content to requesting clients. The content includes a plurality of segment files referenced by an associated manifest document (12), and the nodes are configured to defragment an incomplete piece of content and ensure that a copy stored in each node contain, ail segment files referenced by the manifest document Bach node analyzes the manifest document and the segment files stored in its cache memory (89) to determine whether any segment files referenced by the manifest document are absent from the memory, if so, the node pulls the absent segment files from another node (94) in the CDN to complete the piece of content. The defragmentation may be performed during a period of minimum, network usage to minimize network impact and within a popularity time window to ensure timely storage of the defragmented content in each node.
