US 2026/0121983 A1 · NETWORK INTERFACE DEVICES FOR USER-DEFINED CONGESTION CONTROL

Abstract

Example methods and network interface devices for congestion control are described. In one example, a network interface device may include a first processing layer and a second processing layer. The first processing layer may receive an event notification from the second processing layer. In response to determination that congestion control is required based on the event notification, the first processing layer may determine an adjustment to a packet forwarding parameter by applying a congestion control algorithm. The congestion control algorithm may be one of multiple congestion control algorithms that the first processing layer is programmable to apply. The first processing layer may generate and send an instruction to the second processing layer to perform the adjustment. Based on the instruction, the second processing layer may configure a component to control packet forwarding towards a physical network based on the second value of the packet forwarding parameter.
