    • Systems and methods are described for converting priority based rules into isomorphic longest match rules. Rules for packet processing may be presented to a networking device (100) in priority order, through an interface such as a Command Line Interface (CLI) or from networking applications which may reside on the networking device (100). The networking device (100) may include hardware and/or software designed to perform longest match searches on packets. Prioritized rules may be converted into a data structure for the forwarding layer, so that a longest match search performed by the forwarding layer on the data structure is equivalent to a priority order search on the prioritized rules.
    • 描述了将优先级规则转换为同构最长匹配规则的系统和方法。 可以通过诸如命令行界面(CLI)的接口或可能驻留在网络设备(100)上的联网应用,以优先级顺序向网络设备(100)呈现分组处理规则。 网络设备(100)可以包括旨在对分组执行最长匹配搜索的硬件和/或软件。 优先级规则可以被转换为转发层的数据结构,使得由数据结构上的转发层执行的最长匹配搜索等同于对优先级规则的优先级顺序搜索。
