Abstract
Data compression and decompression methods for compressing and decompressing data based on an actual or expected throughput (bandwidth) of a system. In one embodiment, a controller tracks and monitors the throughput (data storage and retrieval) of a data compression system and generates control signals to enable/disable different compression algorithms when, e.g., a bottleneck occurs so as to increase the throughput and eliminate the bottleneck.
Claims19
A method comprising:
- providing a throughput threshold for a communications channel between a first device and a second device;
- tracking whether a first compressed data provided through said communications channel exceeds said throughput threshold, wherein said first compressed data is provided by a first compression algorithm at said first device, said first compressed data is decompressed by a first decompression algorithm at said second device, and said first compression algorithm and first decompression algorithm are symmetrical;
- and
- providing, if said throughput threshold is exceeded by said first compressed data, a second compressed data through said communications channel, wherein said second compressed data is provided by a second compression algorithm at said first device, said second compressed data is decompressed by a second decompression routine at said second device, and said second compression algorithm and second decompression algorithm are asymmetrical.
