METHOD AND SYSTEM OF COMMUNICATING DEVICES, AND DEVICES THEREFOR, WITH PROTECTED DATA TRANSFER

摘要

A method and a communicating system to enhance the reliability of communication between devices by protecting against failure of a device, e.g. due to power interruption. Additional data is included in communication primitives transmitted between communicating devices. The additional data relates to state data of the device having generated the additional data. The additional data is used to check the state data. The state data may also be derivable from the additional data upon receiving the additional data back from an other device.
