The described method and system enables a client at a branch office to retrieve data from a local hosted cache instead of an application server over a WAN to improve latency and reduce overall WAN traffic. A server at the data center may be adapted to provide either a list of hashes or the requested data based on whether a hosted cache system is enabled. A hosted cache at the client side may provide the data to the client based on the hashes. The hashes may be generated to provide a fingerprint of the data which may be used to index the data in an efficient manner.

Method and system of using a local hosted cache and cryptographic hash functions to reduce network traffic

Storage and communication de-duplication are described. In one or more implementations, a system comprises one or more modules that are implemented at least partially in hardware, the one or more modules configured to utilize one or more algorithms to calculate hashes of chunks of data, the hashes used to replace the chunks in the data for storage locally in the system as well as to communicate the hashes in response to a request received via a network for the data to avoid communicating at least one of the chunks of the data via the network.
