Abstract

A method for aligning packet loss priority information for overload control of a data-packet-switching communications device wherein data packets and respectively allocated packet loss priority information are transmitted to the communications device and buffered in relation to a specific connection. The packet loss priority information is then read from the buffered data packets and modified according to the connection type or the application-specific data traffic type. After the data packet has been switched in the communications device, the original packet loss priority information which was switched with the data packets is re-inserted into the corresponding data packet.
