George Varghese, Srinivasan Venkatachary: Method and apparatus for fast hierarchical address lookup using controlled expansion of prefixes. Washington University, Howell & Haferkamp L C, January 4, 2000: US06011795 (250 worldwide citation)

Many network protocols, including the Internet, have addresses that are structured hierarchically. The hierarchy is expressed by an address prefix P that represents all addresses in the given hierarchical level that starts with prefix P. The hierarchy is not strict and can be overridden by more incl ...
