Based on the former research on IP flows arrival distribution, this paper analyzed the interarrival time distribution and the autocorrelation of IP flows coming from different large-scale networks.
在探讨现有IP流到达分布研究成果的基础上,首先对不同来源的大规模网络的IP流到达时间间隔分布和自相关性进行了分析,发现IP流到达时间间隔均服从Weibull分布,但随着IP流到达密度的增加,Weibull分布的参数α逐渐接近于1,则Weibull分布退化为指数分布;IP流的自相关系数随着被考察IP流流长的增加逐渐减弱,流长为100左右的IP流,其到达过程彼此基本不相关。
补充资料：规模经济/规模不经济
规模经济/规模不经济：规模经济和规模不经济用来说明厂商产量变动从而规模变动与成本之间的关系。对于一个生产厂商而言，如果产量扩大一倍，而厂商的生产成本的增加低于一倍，则称厂商的生产存在着规模经济；如果产量增加一倍，而成本的增加大于一倍，则生产存在着规模不经济。
