Abstract
In a packet-switching network, a stable quality grade is achieved for data services by virtue of the fact that, during the transmission of data packets which are associated with a data service and are assigned to a quality class for the purposes of possible preferential treatment, the transmitter, generally a computer of a service provider, and/or at least one intermediate node establishes the quality of the transmission on the basis of acknowledgements indicating the quality grade and compares it with the quality grade demanded by the data service, and, on the basis of the result of the comparison, the data packets associated with the data service are possibly assigned to another quality class, of which the quality grade demanded by the data service is expected.
