Abstract
A communications system includes a plurality of operational nodes and a plurality of data distribution systems. A data distribution system operating in an active mode manages exchanges of data between the operational nodes and further operable to periodically transmit go passive messages commanding at least one other of the data distribution systems to operate in a passive mode. A data distribution system operating in the passive mode waits for receipt of one of the go passive messages, continues to operate in the passive mode after receiving one of the go passive messages within a predetermined time out period, and transitions to the active mode after the time out period has expired without receipt of one of the go passive messages.
