Congestion control may be provided. A set of rules may allow a congestion control process to switch from delay-mode to loss-mode (e.g., in the presence of loss-based flows) and back to delay-mode (e.g., when loss-based flows stop). Fairness properties of this set of rules may include that the resulting flows may be fair to each other and the flows may also be fair when competing with loss-based flows. Many flows that may be deadlocked in loss-mode (e.g., in the absence of other genuine loss-based flows) may be helped to switch back to delay-mode.
