Abstract

See full text

The present invention provides a method for chunking an object. The method is arranged to provide efficient chunking of objects such that objects can be efficiently updated between a remote machine and a local machine over a network. The chunking algorithm is applicable in networked application such as file synchronization using remote differential compression (RDC) techniques. The chunking algorithm provides enhanced efficiencies by locating chunk boundaries around local maxima.
