Network cache system for reducing redundant data

A method of transmitting a message segment from a local cache management system to a remote cache management system, the method comprising:

• determining a cache hit ratio of a local cache associated with the local cache management system;
• determining a cache hit ratio of a remote cache associated with the remote cache management system;
• determining, by the local cache management system, expected latency costs for transmission of the segment by a plurality of transmission algorithms;
• selecting, by the local cache management system, a transmission algorithm of the plurality of transmission algorithms on a basis of the determined expected latency costs;
• and
• transmitting, using the selected transmission algorithm, at least one message segment from the local cache management system to the remote cache management system.

A computer-readable storage medium having computer executable instructions embodied thereon, wherein, when executed by a processor of a local cache management system, the computer-executable instructions cause the processor to:

• receive a message segment to be transmitted to a remote cache management system;
• determine whether the message segment is represented in a mirrored bloom filter that is associated with the remote cache management system;
• transmit a fingerprint of the message segment to the remote cache management system if the message segment is determined to be represented in the mirrored bloom filter;
• and
• select one of a first transmission algorithm and a second transmission algorithm if the message segment is determined to not be represented in the mirrored bloom filter.
