Bandwidth sensitive data compression and decompression
First Claim
Patent Images
1. 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.

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.
