This Transmission control protocol (TCP) detects congestion only after a packet has been dropped and it would be undesirable to have large queue because it would significantly increase the average delay in the network. In the current high speed networks, it is increasingly important to have mechanisms that keep throughput high but average queue sizes low. This paper presents comparison between two...
Based on conventional active queue management (AQM), random early detection (RED) and modified random early detection (MRED) algorithms, progressive random early detection (PRED) algorithm improved by the progressive adjustment method is proposed. It regulates the packet dropping probability progressively by comparing the instantaneous queue size with the progressive maximum queue threshold parameters...
