The active queue management algorithms stabilize the instantaneous queue length through mapping the congestion measurement into packet drop probability to achieve high throughput and low average delay. Random Early Detection (RED) is widely used AQM mechanism detecting and avoiding the incipient congestion. The detection of congestion is based on priori estimation of congestion and calculation of average queue length and RED queue parameter settings. This paper describes the research work done in recent and new mechanism to estimates the network congestion and avoiding them, so that network performance will improve.
