| 摘 要： | 使用NAT可缓解IP地址的不足，但导致了内网地址和外网地址不一致，并且因地址转换信息未保存而带来了网络行为不可审计和追踪．本文阐述了一种可行的NAT日志的保存方案，即采用在线精简和压缩的方法将海量日志数据保存为压缩文件，亦可将日志保存到数据库中．该方案在实际运行中效果良好．

| Abstract: | Use of NAT alleviates the IP address shortage;however,it results in the inconsistencies between internal network address and the external network address,which brings about the non-auditability and non-trackability of the network behavior due to being unable to save the address translation information.This paper describes a solution of storing NAT log that uses online downsizing and compressing to save the massive log data to compressed files or store them into database.This solution works well in practice. |
