摘要

提出了一种并行处理ip包过滤规则的编译器,提高了网络的安全性,减少了包转发性能的下降。它分析网络管理员指定的包过滤规则之间的相互依赖关系,并将其转换为可并行执行指令的中间程序。介绍了三种类型的编译操作:除法用于将规则划分为并行表达式,简化用于简化冗余规则,删除用于删除不可行的规则。

Parallelization of IP-packet filter rules
A compiler for parallelizing IP-packet filter rules is presented which will improve network security and reduce packet-forwarding performance degradation. It analyzes the interdependence of packet-filtering rules specified by a network administrator and translates them into an intermediate program whose instructions can be executed in parallel. Three types of compiler operations are introduced: division is used to divide the rules into parallel expressions, simplification is used to simplify redundant rules, deletion is used to delete infeasible rules.
