Patent ID: 8260887

Claim:
Method for automatic configuration of an access router, compatible with the DHCP protocol, for specific automatic processing of IP flows from a client terminal in a computer network, as a function of a given set of values of flow processing parameters corresponding to a client line on which the client terminal is located, the access router routing DHCP traffic between the client terminal and any DHCP server on the network capable of proposing a lease to this client terminal, characterized in that it comprises the following steps: a) receiving, by a DHCP relay agent, a DHCP request sent on the network by the client terminal, and inserting, by the DHCP relay agent, information enabling identification of the client line on which the client terminal is located into the contents of the DHCP request sent on the network by the client terminal, and transmitting the request, thus completed with the identification information of the client line, to a DHCP server through the access router; and b) querying a profiles server, using the identification information of the client line as a query key, to obtain values of flow processing parameters associated with it for configuring the access router with the values of flow processing parameters forprocessing traffic flows between the client terminal and the network; said profiles server comprising a database associating and storing values of flow processing parameters corresponding to the client line on which the client terminal is located, with the client line identification information for this terminal; c) configuring the access router with the values of flow processing parameters obtained in step b); and d) processing traffic flows between the client terminal and the network by the access router according to the values of flow processing parameters.
