Compressed prefix matching database searching |
January 11, 2000 |
| Aspects of the invention include a method of conducting a reduced length search along a search path. A node which would otherwise occur between a previous and a following node in the search path is eliminated, and information is stored as to whether, had said eliminated node been pre |

Hash-based translation method and apparatus with multiple level collision resolution |
July 6, 1999 |
| A translation is performed by using a programmable hashing technique on an input number to generate a hashed number. A subset of the hashed number bits are used to index a first hash table. In first hash table locations where a hash collision does not occur, the first hash table entry co |

Compressed prefix matching database searching |
July 14, 1998 |
| Aspects of the invention include a method of conducting a reduced length search along a search path. A node which would otherwise occur between a previous and a following node in the search path is eliminated, and information is stored as to whether, had said eliminated node been pre |
