摘要：A communication system, network, interface, and port architecture are providedfor transporting of data across a ring network. A network node operating as timingmaster generates frames having a preamble, a data field and a time count field, whichrepresents time information. This time information may comprise counted time units likeseconds or transmitted network frames. As the individual bits of a network frame aregenerated and sent on the network, they pass other network nodes and are forwardedthrough the ring bus to the timing master which is receiving parts of the frame it is stillgenerating. This ensures a close control of the frame. In the frame, the received timecount field is compared with the transmitted time count field. If both fields are identical,there is no other timing master on the bus. If there is another timing master on the bus, itwould overwrite the contents of the time count field and therefore the received timecount field would not be equal to the transmitted time count field.
