20080288650 | Method for the Energy-Saving and Timely Transmission of Event Messages - A method and a system-on-a-chip for the guaranteed and energy-saving transmission of event messages is provided in a distributed computer system consisting of a plurality of node computers, which are interconnected by a time-controlled communications system. The node computers establish a common time base of known precision and periodically exchange messages at a prior defined points in time. A guaranteed event message is sent in a sporadic time-controlled message (SZN). The sporadic time-controlled message transports the guaranteed event message and is sent only if the content of this sporadic time-controlled message has been changed since the last time it was sent. The receiver stores the content of an incoming sporadic time-controlled message in a queue until the receiving process has read this content exactly once in a consuming manner. | 11-20-2008 |
