  • TITLE: AN ADAPTIVE CONTROL STRATEGY FOR AQM ROUTERS SUPPORTING TCP FLOWS
  • AUTHORS: Yossi Chait, Salomon Oldak, C.V. Hollot and Vishal Misra
  • ABSTRACT: This paper describes the development of an adaptive algorithm for active control management (AQM) routers supporting a varying number of long-lived TCP flows. We motivate the need for adaptation by focusing on the plant's high-frequency gain which is directly related to stability margins and speed of response. We show that the high-frequency gain of the linearized plant is inversely proportional to this number which can vary by at least an order of magnitude. Our adaptive algorithm -- the Externally Excited Adaptive Loop (EEAL) -- is shown to achieve improved queue level management compared with that achieved using RED and PI based AQMs.
