摘　　要：随着网络技术的飞速发展,互联网正处于第四版互联网协议(IPv4)向第六版互联网协议版本(IPv6)过渡的时期,同时大量网络设备也逐步开始支持双协议栈模式,另外对数据流的分析和研究一直是入侵检测、流量识别等多领域的研究基础和重点,因此针对双栈环境下数据流的分析和研究应运而生。本文通过实验对三种不同的哈希函数在双栈环境下数据分流效果进行分析,并采用标准差和方差的方法对分流效果、均匀性等方面进行数据对比,实验结果表明改进的异或循环哈希算法在双栈环境下具有较好的性能,为入侵检测、流量识别等方面的研究提供实验依据,本文同时给出下一步的研究方向以及双栈环境下流量的研究重点。With the rapid development of network technology, now in the fourth edition of the Internet Protocol （ IPvd ） to the Internet Protocol Version 6 （IPv6） transition, a large number of network devices have gradually begun to support dual - stack mode. Data flow analysis and research has been focused on the research base of intrusion detection, traffic identification and other areas, thus came into being analysis under a dual - stack environment for data streams. This paper tests on three different hash functions diversion of dual - stack environment data, data comparison in the flow classification, uniformity and other aspects, and then get a better performance of the improved XOR cycle hash algorithm under a dual - stack environment, therefore provides experimental basis in the intrusion detection, identification and other aspects of traffic. At last this paper also gives future research directions and research priorities under the dual - stack environment flows.
