Predictive loss pattern queue management for Internet routers

An active queue management algorithm called predictive loss pattern (PLoP) is presented to give preferred service over short time intervals to particular flows that have previously been discriminated instead of enforcing static reservations. The probability of packet drop is made dependent on flow history and flow type. This allows basic protection of burst-loss-sensitive flows during transient and persistent congestion, keeping only partial per-flow state. The algorithm does not require any specific cooperation of the applications and gives an incentive to build loss-resilient applications using end-to-end quality of service enhancement, which can build on the enforced predictive loss pattern.
