This paper investigates the implementation of a class of active queue management algorithms (AQM) whose measure of congestion includes packet arrival rate, such as REM and GREEN, in a combined input and output queued (CIOQ) switch. We propose a structure with one AQM per output port and we analyze the constraints on the switch fabric speed that this imposes. A two queue model of a CIOQ switch is developed and simulated to validate our design and compare its performance with a tail-drop queue switch.
