摘　　要：为解决IPv4面临的网络地址枯竭的问题,IETF提出了很多方案,其中NAT(Network Address Translation,网络地址转换)是目前常用的一种方案。NAT分为两类:一类是基本NAT,另一类是NAPT。与基本NAT相比,NAPT具有更高的地址利用率,目前采用最多是NAPT。对目前的NAPT原理进行阐述,并分析目前其存在的不足并提出一种改进算法。In order to solve the problem of IP address depletion which IPv4 faces,IETF proposed many proposals.NAT(Network Address Translation) is one of the proposal being commonly used presently.NAT can be divided into two kinds:one is basic NAT,and the other is NAPT (Network Address Port Translation).Compared with NAT,NAPT holds higher utilization rate of the address,and thus,it's mostly used at present.This paper elaborates the principle of NAPT,analyzes the defects of the current NAPT,and then proposes an improved algorithm.
