Abstract
Systems and methods efficiently distribute information, such as path name, attributes and object information, corresponding to changes in a content repository to remote nodes in a network using storage-layer/object-based protocols. A difference monitoring client monitors name space and object space changes by identifying inodes which have been modified on storage volumes between two or more snapshots. The monitoring client builds a list which may include name information, object space information and attributes such as file size and permissions for each of the changed inodes that is utilized to update the edge nodes. Systems and methods also provide for geo-scale content distribution from a central repository to edge nodes using a storage-layer/object protocol. A caching mechanism is utilized to cache requested content at an edge node. Cached content may be maintained at the edge node during use and/or for an additional predetermined period. Difference monitoring client may track such cached content.
