Abstract
A method is provided for asymmetrically compressing data communicated between a ground platform and multiple airborne platforms. The method includes packet compressing ground-based data so as to preserve routing information while compressing the remaining data. The packet-compressed data is then transmitted to the airborne platforms. The method also includes bulk compressing airborne-based data so as to maximize compression and minimize use of available bandwidth. The bulk-compressed data is then transmitted to the ground platform.
Claims27
A method of transmitting data between a first location and a second location comprising:
- obtaining a first data stream at said first location;
- packet compressing said first data stream;
- sending said packet compressed first data stream to said second location;
- obtaining a second data stream at said second location;
- bulk compressing said second data stream;
- and
- sending said bulk compressed second data stream to said first location.
A method of transmitting data between a ground segment and an airborne segment of a network comprising:
- obtaining a first data stream at said ground segment;
- packet compressing said first data stream;
- sending said packet compressed first data stream to said airborne segment;
- packet de-compressing said packet compressed first data stream at said airborne segment;
- obtaining a second data stream at said airborne segment;
- bulk compressing said second data stream;
- sending said bulk compressed second data stream to said ground segment;
- and
- bulk de-compressing said bulk compressed second data stream at said ground segment.
A communications network including a forward link and a return link, the network comprising:
- a packet compressor on said forward link for packet compressing data sent thereover while preserving routing information contained in said data;
- and
- a bulk compressor on said return link for bulk compressing data sent thereover to minimize bandwidth consumption.
