Abstract

A találmány rendszer (10), berendezés és eljárás gyorsítottcsomagszűréshez, amely tartalmaz csomagot küldő forrás csomópontot, acsomagot fogadó rendeltetési csomópontot, és a forrás csomópont és arendeltetési csomópont között elhelyezett, legalább egy szabályszerint csomagszűrést végző tűzfalat (18). A rendszer tartalmaz atűzfallal (18) kapcsolatban lévő, a tűzfaltól (18) legalább egyutasítást fogadó, a csomagot a tűzfal (18) előtt fogadó előszűrőmodult (30), ahol a legalább egy utasítás szerint engedélyezettnekminősülő csomag az előszűrő modul (30) által van kezelve, ellenkezőesetben pedig a csomag az előszűrő modul (30) által a tűzfalhoz (18)továbbítva kezelésre, és ahol a legalább egy utasítás alapjánvégrehajtott csomagelemzés szűkebb körű, mint a tűzfal (18) általvégrehajtott csomagszűrés.
