The invention relates to a method for traffic control in a communications network, in which method the transmission of a data packet to its destination address is inhibited on the basis of the source or destination address of the data packet and in which method bindings defined between middleware-level and network-level information are utilized in traffic control at the network-level so that the traffic flow in the communications network can be controlled on the basis of barring lists at the middleware level. The invention is based on combining Internet middleware facilities with programmable active networks and/or routers. An automatic monitoring system is configured so that traffic outbound from a given subscriber connection and targeted to another given subscriber connection is passed via the traffic monitoring system. Herein, a precompiled middleware-level name list is utilized wherefrom the middleware-level names used by said given subscriber connection are selected (201) to form a barring list. On the basis of the thus formed middleware-level barring list, into the monitoring system by way of reading the response messages of a name server system is compiled (205) a network-level barring list, whose addresses are maintained valid not longer than the validity time indicated in the response message of the name server system, thus accomplishing the novel technique of traffic control on the basis of a subscriber-specific middleware-level barring list. |
