    • A packet processing device has a search engine module including an associative memory for transferring a packet on the basis of an entry mapping to route information, a first processor taking charge of a pre-search process before a process of the packet to the search engine module, and a second processor taking charge of a post-search process for executing a process of routing the packet on the basis of a search result of the search engine module. In this architecture, the packet processing device further has a table used for transferring and receiving information between the first processor in charge of the pre-search process and the second processor in charge of the post-search processor, and identifying information in a specified field of the table is transferred through the search engine module as a transparent medium.
    • 分组处理设备具有搜索引擎模块,该搜索引擎模块包括用于基于对路由信息的条目映射来传送分组的关联存储器,在分组处理之前负责搜索前处理的第一处理器到搜索引擎模块 以及负责搜索后处理的第二处理器,用于基于搜索引擎模块的搜索结果执行路由分组的处理。 在该架构中,分组处理装置还具有用于在负责预搜索处理的第一处理器和负责后搜索处理器的第二处理器之间传送和接收信息的表以及指定字段中的识别信息 的表格作为透明介质通过搜索引擎模块传输。
