THE CLASSIFICATION METHOD OF PACKETS BY USING THE DUAL TCAM TABLES

机译:使用双TCAM表对包装进行分类的方法

摘要

A classification method of packets by using dual TCAM(Ternary Content Addressable Memory) tables is provided to be capable of storing packet classification rules at two TCAM tables by dividing the rules, according to expression types of the packet classification rules, thus required size of a TCAM is reduced. When packets are received, information is extracted(401). A general table is searched(402). If the searching is successful, associative additional information of searched results is read to find out a matched list and to find out whether an additional searching process is conducted(404). If the additional searching process is interrupted, the currently matched rules are determined as final results(406).
