US 2026/0149671 A1 · FAST CONVERGENCE DURING AN INCAST EVENT

Abstract

Embodiments herein describe throttling traffic using an achieved bandwidth delay product (BDP). As a sending device receives acknowledgments (ACKs) from a receiving device, the sending device determines whether the ACKs are marked to indicate the corresponding packet experienced congestion in the network. In addition, the sending device determines a delay associated with the packet being transmitted from the sending device to the receiving device. If this delay is much greater than a target delay threshold and the ACK indicates there was, then a transmission limit (e.g., a congestion control window size or a transmission control rate) is set based on an achieved BDP.

Dependent claims

A method, comprising:

transmitting a packet from a sending device to a receiving device;
determining a delay based on receiving an acknowledgement (ACK) from the receiving device;
and
upon determining (i) the ACK indicates congestion in a receive (RX) queue when the packet was transmitted from the sending device to the receiving device and (ii) the delay satisfies a second delay threshold that is greater than a target delay threshold, setting a transmission limit used to transmit packets to the receiving device based on an achieved bandwidth delay product (BDP).
