  • Communications network data compression control system and method
    Patent number: 5131016
    Abstract: Data communication nodes in a network comprising a plurality of nodes linked together to form communication paths negotiate by passing messages to identify to one another the maximum supportable degree of data compression capability. Logical comparisons are made at each node between indications received from upstream and downstream nodes, if any, regarding their own or their received indications of data compression capability with the present node's own degree of compression capability. This enables logical decisions to be made to suport the maximum degree of compression capability over each link or portion of a link between terminal nodes which define the ends of the overall link, thus improving data transmission by providing the highest degree of supportable compression over the longest path length.
