Abstract: A method of communicating data from a data source (10) on one bus system (1) to a data sink (30) on another bus system (3) whose cycle rate is similar to but not synchronised with that of the first bus system comprises the steps of determining the tolerances with respect to frequency between the first and second bus cycle periods, assembling the data for transmission into packets, allocating a variable size, dependent on the tolerances, data payload to the packets, and including within the packets a header indicating the size of the payload. The receiving bus (3) receives these packets and extracts the data payload from the packets using the packet header indication of the size of the data payload.
