Abstract
In the RPR steering mechanism, the head stations, counted from the breakpoint on each ringlet, may seize more bandwidth of high priority traffic than their downstream nodes. This study proposes an adaptive control scheme of reserved bandwidth to throttle the add traffic flows of the head nodes and reallocate network bandwidth more fairly. With this scheme, we can control the classA1 and classB reserve rate dynamically, and adjust the downstream rate according to the congestion condition. In our simulations, we see that the classA frame delay can be decreased largely, and the global system throughput can be increased significantly.
