Title
(EN) DETERMINING THE PHYSICAL LOCATION OF A CLIENT
(FR) DÉTERMINATION DE L'EMPLACEMENT PHYSIQUE D'UN CLIENT
Abstract
(EN) Determining a physical location of a client, including: determining a network transmission time associated with a first server and a network transmission time associated with a second server; determining a set of key parameters for the first server and a set of key parameters for the second server; determining a distance between the client and the first server and a distance between the client and the second server based at least in part on inputting the network transmission time associated with the first server, the network transmission time associated with the second server, the set of key parameters for the first server, and the set of key parameters for the second server into a data processing model; and determining the physical location associated with the client using the distance between the client and the first server and the distance between the client and the second server.
(FR) La présente invention concerne un procédé de détermination de l'emplacement physique d'un client, le procédé comprenant : la détermination d'un temps de transmission réseau associé à un premier serveur et d'un temps de transmission réseau associé à un second serveur ; la détermination d'un ensemble de paramètres clés pour le premier serveur et d'un ensemble de paramètres clés pour le second serveur ; la détermination d'une distance entre le client et le premier serveur et d'une distance entre le client et le second serveur au moins partiellement sur la base de l'entrée du temps de transmission réseau associé au premier serveur, du temps de transmission réseau associé au second serveur, de l'ensemble des paramètres clés pour le premier serveur et de l'ensemble des paramètres clés pour le second serveur dans un modèle de traitement de données ; et la détermination de l'emplacement physique associé au client au moyen de la distance entre le client et le premier serveur et de la distance entre le client et le second serveur.
