Abstract

Brannvegg (3) for å kontrollere datapakketrafikk i et nettverk mellom interne og eksterne nettverk (1,5,4) omfattende filtreringsmidler for å velge fra et totalt sett av regler, avhengig av innholdet i datafeltene til en datapakke som overføres mellom nettverkene, hvor en regel er anvendbar på datapakken, for å blokkere pakken eller å sende pakken gjennom brannveggen (3). Oppslagsmidler (8) utfører et 2-dimensjonalt oppslag av kilde og mottakeradresser til pakken i et sett av adresseprefikser, hvori hvert prefiks har et undersett av regler av det totale sett av regler, for å finne et prefiks, via den representasjon, forbundet med kilde og mottakeradresser, og midler (10) for regelmatching, basert på innholdet av datafeltene for å finne regelen som er anvendbar for datapakken.
