Abstract:
A method for differencing data communications using a message queue, the method comprising the steps of:intercepting a data stream having an associated type from a host application prior to transmission of the data stream through the message queue on an external communication link to a destination computer;segmenting the data stream based on the associated type to provide a plurality of segments;placing message identifiers associated with the plurality of segments into the message queue;selecting one of the plurality of segments from the message queue for transport;determining if the selected segment has previously been transported;reducing the selected segment to a differenced communication format based upon whether it has previously been transported to provide a reduced segment;emitting the reduced segment;verifying that the differenced communication format of the reduced segment is known to the destination computer;dequeuing the selected segment; andplacing the selected segment in a differencing cache if it has not previously been transported.
