  • Normalized proportional synchronous bandwidth allocation in a token ring network by setting a maximum message transmission time
    Patent number: 5404424
    Abstract: A method for real time message transmission in a token ring network is provided. The method initializes each node in the network, including setting a maximum message transmission time H.sub.i such that ##EQU1## is the transmission time of a message in a message stream, P.sub.i is the period length of the message stream, TTRT is the target token rotation time, and .tau. is the portion of TTRT that is unavailable to transmit messages. The messages are then transmitted when a token arrives at a node for the duration of H.sub.i. Using this method with the timed token protocol, the synchronous messages are guaranteed to be transmitted before their deadlines if the utilization of synchronous messages is no more than 33% of available utilization.
