This paper introduces Adaptive Backpressure, a novel scheme that improves the utilization of dynamically managed router input buffers by continuously adjusting the stiffness of the flow control feedback loop in response to observed traffic conditions. Through a simple extension to the router's flow control mechanism, the proposed scheme heuristically limits the number of credits available to individual virtual channels based on estimated downstream congestion, aiming to minimize the amount ofdoi:10.1109/iccd.2012.6378673 dblp:conf/iccd/BeckerJMD12 fatcat:shyc3jf6rfcpzaxuwesuxpytjm
