摘要： A communication system, network, interface, and port architecture are provided for transporting data across a ring network. A network node operating as a first timing master generates a set of frames, each frame having a preamble, a data field and a time count field, which represents a portion of the time information associated with the set of frames. This time information may include counted time units, like seconds, or a number of generated and transmitted over the network. As the individual frames of a set of frames are generated and sent on the network, they pass other network nodes and are forwarded through the ring bus to the first timing master which receives at least a portion of the set it is still generating. This enables a received time count field to be compared with a transmitted time count field of the same set. If the fields are identical, there is no other timing master on the bus. If there is another timing master on the bus, the additional timing master would overwrite the contents of the time count field propagating through the network; therefore, the received time count field would not be equal to the time count field being transmitted by the first timing master.
