A method and compiler for compiling hierarchical command based policy rules to a flat filter list structure adapted for storage in a Content Addressable Memory (CAM), wherein the policy rules are organized in a tree-structure of classifiers. First, all of the possible search paths in the tree structure are found, and then only the valid search paths according to defined criteria are added to the flat filter list. The CAM may be a Ternary Content Addressed Memory. |
