Patent

CA 2399014

The invention takes advantage of the capability of assigning multiple addresses to a single host to improve the processing performed by a firewall in a packet-switched network. The host utilizes a plurality of addresses to refer to groups of related tasks on the host. When the firewall receives an outbound packet having one of these source addresses, it authorizes further inbound packets addressed to the particular source address.

La présente invention tire partie de la possibilité avantageuse d'affecter des adresses multiples à un seul hôte pour améliorer le traitement d'un pare-feu dans un réseau à commutation par paquets. Cet hôte utilise une pluralité d'adresses à renvoyer à des groupes de tâches afférentes à l'hôte. Lorsque le pare-feu reçoit un paquet sortant contenant une des ces adresses source, il autorise d'autres paquets sortants adressés à l'adresse source particulière.
