INCREMENTAL UPDATES FOR ORDERED MULTI-FIELD CLASSIFICATION RULES WHEN REPRESENTED BY A TREE OF LONGEST PREFIX MATCHING TABLES
An apparatus includes a memory and a processor. The memory may be configured to store at least a portion of a multi-level tree representation of an ordered multi-field rule-based classification list. The tree representation includes at least one non-leaf level and one or more leaf levels. Each entry...

Zusammenfassung: | An apparatus includes a memory and a processor. The memory may be configured to store at least a portion of a multi-level tree representation of an ordered multi-field rule-based classification list. The tree representation includes at least one non-leaf level and one or more leaf levels. Each entry in the at least one non-leaf level contains a count value indicating a number of rules having a matching field. Entries in at least one of the one or more leaf levels include rule pointers arranged in priority order. The processor may be configured to incrementally insert or delete rules, while preserving ordering semantics of the tree representation. |
