Abstract :
This paper describes a low-cost error control scheme for hard real-time communication on FDDI networks. As the existing bandwidth allocation schemes decide the capacity vector based on the worst case condition, there is usually extra available transmission time for each message stream. The proposed error control scheme uses this extra bandwidth for the retransmission of a subpacket, without additional bandwidth for the error control procedure. Simulation results shows that the proposed scheme enhances the deadline meet ratio by 50% at maximum
