摘　　要：随着社交网络、在线视频、电子商务、即时通信及微博等新兴业务的不断涌现及迅速发展,网络中UDP流量的比例及特性均发生了较大变化。文章通过对现有的流超时策略进行分析,指出其适用于UDP流量时存在的局限及不足,针对实际UDP网络流特性展开研究,并提出了一种UDP流区分更新的流超时策略(DUToS)。实验结果证明,DUToS算法能够更好地适用于UDP流量,有效改善了网络流量测量的性能。With the continuous emergence and rapid development of social network, online video, e-commerce, instant message, micro-blogging, etc. , great changes have taken place in the percentage and property of UDP traffic on the Internet. By the analysis of the state-of-the-art flow timeout strategies, their deficiencies and shortcomings are pointed out when applied in UDP traffic. Then, a differentiated updating timeout strategy （DUToS） for profiling UDP flows is proposed based on the analysis of the property of real LIDP flows. Ex- perimental results show that the algorithm of DUToS is more suitable for UDP traffic and can effectively im- prove the performance of network traffic measurement system.
