传统防火墙技术可分为两大类：一类是基于包过滤技术，另一类是代理技术．当前各种防火墙的实现中，对非服务攻击（包括欺骗攻击、源路由攻击等）的防范乏力，而资料显示这类攻击又是极为常用和易成功的．该文提出了路由记录分析（ＲＲＰ）技术，专门用于解决该类问题．
Traditional firewall technology can be divided into two categories: one is based on packet filtering technology, and the other is proxy technology. In the current implementation of various firewalls, the lack of preventive measures against non-service attacks (including spoofing attacks and source routing attacks) shows that such attacks are extremely common and easy to be successful. This paper proposes Route Record Analysis (RRP) technology, which is designed to solve this problem.
