| 摘 要： | 接入Internet成为当今信息业最迫切的需求，而IP地址的现行标准是IPv4，IP地址严重不足．从IPv4到IPv6还需要一段时间。因此NAPT（网络地址端口转换）技术被广泛应用．识别NAPT内网的主机数目对于ISP（信息服务商）显得尤为重要．由于存在软件NAPT和硬件NAPT，本文提出多种方法结合的方案，通过对IP数据报中的IVid（IP标识），Source-port（源端口）进行统计，根据结果确定是否使用了NAPT技术，并对软件NAPT识别出NAPT服务器主机与NAPT客户端主机．结合Cookie提取技术。确定用户数．

| Abstract: | Internet connection is very important today.IP address has been assigned depending on IPv4,which is not enough.It must need more time to migrate from IPv4 to IPv6,so NAPT technology is used widely.ISP attempts to know how many hosts there are behind the NAPT device.There are two types of NAPT:software NAPT and hardware NAPT.The technique based on IPid,Source-port,TTL,analyzing the traffic packets can recognize whether NAPT had been used or not.It also can distinguish the server from the client by means of s... |
