Adaptive Hurst-Sensitive Active Queue Management

Entropy, 2022
An Active Queue Management (AQM) mechanism, recommended by the Internet Engineering Task Force (IETF), increases the efficiency of network transmission. An example of this type of algorithm can be the Random Early Detection (RED) algorithm.
