Method and apparatus for physical width expansion of a longest prefix match lookup table |
摘要 |
A lookup unit matrix combines a plurality of lookup units to provide a longest prefix match for a search key longer than the lookup unit's mapper key. A portion of the search key is provided to each of the plurality of lookup units in a single search request issued to the lookup unit matrix. Each lookup unit in the lookup unit matrix performs a multi-level search for the result value based on the portion of the search key forwarded as the mapper key and the result of a multilevel search in the previous lookup unit. The search results in a value corresponding to the search key stored in a single location in one of the lookup units.
