摘要:
已有的AQM算法都没有充分考虑到长时滞对算法性能的影响,该文利用频率域模型降价拟合方式建立了TCP流量控制中主动队列管理AQM系统的等效模型,应用控制理论中的内模补偿原理设计鲁棒的时滞补偿AQM算法(IC-AQM),克服了长时滞给对队列稳定造成的不利影响,仿真结果表明,这种新算法在长时滞小期望队列综合性能明显优于已有的RED、REM、PI等算法,链路利用率大大提高。
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.
