针对日益严重的网络拥塞现象,在传统的BLUE算法的基础上建立了一种新的主动队列管理方法(Im—muneclonalsimulatedannealing-basedBLUE,IBLUE).该方法重新定义队列长度变化范围以及丢包概率,并且利用免疫克隆模拟退火算法来刻画队列长度变化情况.其次,以实际数据进行仿真实验,深入分析了影响该方法的关键因素,同时通过对比BLUE和BLUE^+算法性能,结果表明IBLUE具有较好的适应性.
In order to mitigate the network congestion problem, a novel active queue management method (Immune clonal simulated annealing-based BLUE, IBLUE) is proposed by BLUE algorithm. In this method, the range of queue length and dropping rate are re-defined, and the average queue length is depicted by immune clonal simulated annealing. Then, a simulation with actual data was conducted to study key factor in IBLUE. The results show that, compared to BLUE and BLUE+ , IBLUE has better adaptability.
