Abstract
Various techniques for queue management based on random early detection (RED) are disclosed herein. In particular, a method for generating a drop probability for an incoming packet in a device having a queue to buffer packets between segments of a network is provided. The method comprises determining, upon receipt of an incoming packet, a size of the queue and determining an error based at least in part on a difference between the queue size and a threshold. The method further comprises determining a drop probability for the incoming packet based at least in part on the error and a constant gain factor. The constant gain factor may be based at least in part on a linearized second order dynamic model of the network.
