TRAFFIC RESTRICTION IN PACKET-ORIENTED NETWORKS BY MEANS OF LINK-DEPENDENT LIMITING VALUES FOR THE TRAFFIC PASSING THE NETWORK BOUNDARIES

摘要

The invention relates to a method for controlling the access to a packet-oriented network. An authorization check is carried out for a group of packets by means of a limited value affecting a partial section of the network, the limiting value representing a boundary for all traffic which circulates over the partial section and passes over the input nodes or the output nodes of the network. The transmission of the group of data packets is not authorized if an authorization of transmission would lead to traffic exceeding the limiting value. The access control can be carried out for all partial sections over which the packets of the flow are to be transmitted. Overload and blockage situations in the partial section concerned can be avoided by the access control. The inventive access control can be combined with other access controls in order to achieve an optimized use of the network.
