CONTROL DEVICE FOR THE CENTRALIZATION FORCE OF SELECTED TRAFFIC IN A NODE OF AN IP NETWORK

摘要

A device (D) is dedicated to the control of traffic within a native node (R1) constituting within an Internet Protocol (IP) communications network a native agent for at least a first mobile terminal (TM) having a first IP address and momentarily attached to a foreign subnet (S3). This device (D) comprises loaded control means (MC), when the native node (R1) receives a first message associated with a first source IP address of the first mobile terminal (TM) and at a second address IP destination of a second terminal (TC) and requiring the establishment of a decentralized traffic between these first (TM) and second (TC) terminals, to check if the first IP address corresponds to an IP address of a list of chosen IP addresses, and in case of correspondence, i) to prohibit the native node (R1) to transmit the first received message to the second destination IP address, ii) to generate a response message signaling the incapacity of the second terminal (TC) satisfying the first message and associated with a destination IP address equal to the first IP address; and iii) instructing the native node (R1) to transmit the response message to the first IP address.
