Disclosed are systems and methods for communicating with a sender machine and a receiver machine, and analyzing a bitmask associated with a message to be sent from the sender machine to the receiver machine, such that the bitmask comprises one or more presence bits and one or more absence bits, such that the presence bits indicate that an associated field of the message are included in the message and the absence bits indicate that an associated field of the message are omitted in the message. The systems and methods also dynamically determine compression instructions to compress the bitmask, and provide the compression instructions to the sender machine, wherein the compression instructions reduce size of the bitmask associated with the message to be sent to the receiver machine.
