摘　　要：随着信息技术的发展,计算机网络已经遍布社会的各个方面,手机等移动设备更是成为人们日常生活的重要部分,因此相关用户特征及网络使用的研究越来越成为当下的热点。目前研究用户特征和网络使用情况的方法都是基于TCP流量进行的,但是当用户大量增加时,原始包的捕获和存储将变得非常困难。还有很多研究有线网络和无线网络的方法,但是使用DHCP将两者进行比较研究的情况却很少见。通过大规模测量和解析校园网中有线和无线网络的DHCP数据,可以获得网络用户登录情况、网络使用情况、用户终端操作系统、终端设备供应商等。研究发现了一些有趣的信息,这些信息反映了移动网络的发展趋势以及一些将要面临的挑战。Internet is playing a more and more important role in today’s society.Wireless network and mobile device are becoming part of our lives.So it’s significant to learn about the information of the us-ers or network usage.Both network methods of user characterizing and network usage are mostly bas-ed on TCP traffic study.But when facing to a large amount of users,raw packet capturing and storing would be difficult.There were previous methods researched the fixed network or wireless network,but a comparative study is hardly seen.So in this paper,we measured the large-scale fixed and wireless network of our campus,via DHCP analysis.We analyzed the user behaviors such as distribution of user join time,user count.We also studied about user’s operating system by introducing DHCP OS fingerprin-ting.We found some interesting results,which revealed the trend of mobile network and some challenges might be brought in.
