  • System for synchronous measurement in a digital computer network
    Patent number: 4982185
    Abstract: A synchronous distributed measurement system in a digital computer network comprising a master node and a plurality of slave nodes interconnected by communications links to form a ring. The master mode includes a message transmitter for transmitting a synchronizing message over a communications link. Each slave node includes an operational portion for performing selected operations. A message receiver receiving the synchronizing message from a communications link, and a message transmitter responsive to receipt of the synchronizing message for retransmitting the synchronizing message over the communications link. An operational control portion starts the measurement portion a selected delay time after the message receiver receives the synchronizing message, the delay time providing that the operational portions of the slave nodes perform the measurements in synchronization.
