Abstract:
The present active queue managem ent( AQM ) schemes neg lect the impact on the perfo rmance caused by large delay. B ased on the model reduct ion theory in frequency-domain, TCP AQM system mode l are proposed, and a robust delay compensation AQM schem e ( IC - AQM) app lying the princ ip le o f internalmode compensation in con tro l theory is designed. The new scheme restricts the negat ive impact on the queue stability caused by the large delay. The simulat ion results show that th is new schem e is superior to that of the present RED, REM and PI schemes w hen the netw ork is in large delay and small queue leng th, and the link u tilizat ion is increased.
