  • Network cache system for reducing redundant data
    Patent number: 8949546
    Abstract: Embodiments include a local cache management system that is configured to be coupled to a local cache and that includes an index engine configured to store fingerprints of message segments stored in the local cache and a redundancy management engine coupled to the index engine. The redundancy management engine includes an adaptive emitter configured to receive a message segment to be transmitted to a remote device, determine expected latency costs of a plurality of transmission algorithms, and select a transmission algorithm, such as by selecting the lowest expected latency cost. The adaptive emitter is also configured to determine whether the message segment is stored within a remote cache management system associated with the remote device, and transmit the message segment through a network to the remote cache management system using the selected transmission algorithm upon a determination that the message segment is not stored within the remote cache management system.
