• The distributed nature of routing and flow control in a register-insertion ring topology complicates priority enforcement for real-time systems. Two divergent approaches for priority enforcement for ring-based networks are reviewed: a node-oriented scheme called preemptive priority queue and a ring-wide arbitration approach dubbed TRAIN. This paper introduces a hybrid protocol named directed flow control that combines node- and ring-oriented flow control to yield greater performance. A functional comparison of the three protocols as implemented on the scalable coherent interface is presented, followed by performance results obtained through high-fidelity modeling and simulation.
