Abstract
A firmware controller of a node of a distributed system determines a self-regulation threshold for at least one metric associated with traffic transmitted via an interconnect. The threshold is set to a value lower than the maximum permitted by the interconnect protocol. The controller transmits a request to an application-layer traffic endpoint to limit traffic based on the threshold. A hardware congestion management unit collects measurements on traffic metrics, including at least one metric other than the one for which the threshold is defined. Based on measurements obtained from the hardware congestion management unit, the controller modifies the self-regulation threshold and notifies the application-layer endpoint.
