ABSTRACT:
A method for transmitting a message by compressed data transmission between a sender and a receiver using connectionless or connection oriented protocols. The sender gateway assures that the appropriate handling of the message data is made by knowing the transmission protocol(s) used. T The rules and structures of the protocol(s) must be known to be able to use a compression method ideally suited to the needs of the particular protocol. Both gateways analyze the data stream between sender and receiver, compress outgoing and decompressing incoming data. For connection oriented protocols, differently structured data structures are transmitted during a connection. To distinguish different data structures, the gateway providing for compression examines the data to be transmitted and, by knowing the definition of the protocol used and the state of the machine, it can control the compression to use a file-oriented compression on certain parts of the data stream.
