Title
(EN) ARRANGEMENT FOR TRACKING IP ADDRESS USAGE BASED ON AUTHENTICATED LINK IDENTIFIER
(FR) SYSTEME DE SUIVI DE L'USAGE D'ADRESSES IP SUR LA BASE D'UN IDENTIFICATEUR DE LIAISON AUTHENTIFIE
Abstract
(EN) Link layer authentication information is supplied by a link layer authentication device to an access router for tracking IP address usage by a client device. The authentication information supplied to the access router includes an authenticated client identifier and a corresponding authenticated link identifier for the client device that attached to the network based on the authenticated link identifier. The access router, in response to receiving a message that specifies the authenticated link identifier and a source IP address, adds the source IP address to a cache entry that specifies the authenticated client identifier and the corresponding authenticated link identifier, and outputs to an audit resource a record that specifies the source IP address and the authenticated link identifier.
(FR) L'invention concerne une donnée d'authentification d'une couche liaison fournie par un dispositif d'authentification de couche liaison à un routeur d'accès pour le suivi de l'usage d'adresses IP par un dispositif client. La donnée d'authentification fournie au routeur d'accès contient un identificateur client authentifié et un identificateur liaison authentifiée correspondant d'un dispositif client qui est raccordé au réseau sur la base de l'identificateur liaison authentifié. Le routeur d'accès, en réaction à la réception d'un message qui spécifie l'identificateur liaison authentifié et une adresse IP source, ajoute l'adresse IP source à une entrée cache qui spécifie l'identificateur client authentifié et l'identificateur liaison authentifiée correspondant, et envoie à une ressource de contrôle un enregistrement qui spécifiee l'adresse IP source et l'identificateur liaison authentifié.
