Improved non-real-time communication in FDDI networks with real-time traffic

The fiber distributed data interface (FDDI) is suitable for real-time communication. A scheme for reducing the response time of non-real-time messages while still providing the same quality of service to real-time messages is proposed. In the proposed approach, non-real-time messages are transmitted ahead of real-time messages unless it is absolutely necessary to transmit real-time messages first in order to meet their deadlines. Simulation results show that a substantial reduction in the mean response time of non-real-time messages is achieved when using the proposed approach
