Abstract: In one aspect, replacing padding characters from a body of a GIOP message with paddding character replacement control sequences compresses the message before transmission. In another aspect of the invention, replacing paddding character replacement control sequences with padding characters in the body of a compressed GIOP message decompresses the message upon receipt. In a further aspect, replacing repetitive strings of characters in the body of a GIOP message with repetitive replacement control sequences compresses the GIOP message before transmitting. In yet a further aspect, replacing repetitive replacement control sequences with repetitive sequences of values in the body of GIOP message for control sequences upon receipt of the message decompresses the message.
