Compression for asymmetric data links
First Claim
Patent Images
1. 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.

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.

25. 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.
