Data bus system with resource control compensating for limited transmission capacity

摘要

A data bus system comprises a number of stations which are interconnected via a bus. The bus has a limited data transmission capacity available. From a transmitter station a resource control station reads which part of the available transmission capacity is required for the relevant transmitter. The resource control station allocates the required transmission capacity to the relevant transmitter station if adequate transmission capacity is available; it is only in that case that transmission by the relevant transmitter station is enabled.
