Title (EN) DETERMINING PATTERN MATCH BASED ON CIRCUIT MATCH AND HASH VALUE MATCH
(FR) DÉTERMINATION D'UNE CORRESPONDANCE DE MOTIFS D'APRÈS UNE CORRESPONDANCE DE CIRCUITS ET CORRESPONDANCE DE VALEURS DE HACHAGE
Abstract:
(EN) Examples disclosed herein relate to pattern matching. In one example, a notification from a hardware circuit of a device is received. In the example, the notification indicates that a first packet portion of a packet received by a network interface of the device is matched to a first pattern portion of a pattern. Further, in the example, the device hashes a second packet portion of the packet to generate a hash value based on a hash size determined via information received from the hardware circuit. In the example, the device determines that the hash value matches a pre-hash value corresponding to a second pattern portion of the pattern.
(FR) L'invention concerne, dans les exemples décrits ici, la mise en correspondance de motifs. Dans un exemple, une notification en provenance d'un circuit matériel d'un dispositif est reçue. Dans l'exemple, la notification indique qu'une première partie de paquet d'un paquet reçu par une interface de réseau du dispositif concorde avec une première partie de motif d'un motif. En outre, dans l'exemple, le dispositif effectue un hachage d'une deuxième partie de paquet du paquet pour générer une valeur de hachage basée sur une taille de hachage déterminé via des informations reçues en provenance du circuit matériel. Dans l'exemple, le dispositif détermine que la valeur de hachage concorde avec une valeur avant hachage correspondant à une deuxième partie de motif du motif.
