ABSTRACT:
A method for optimizing the use of network resources for the transmission of data signals, such as voice frames, between network units over an IP-packet supporting network. The data frames are obtained using codecs, which may have a different mouth-to-ear transmission delay, from data samples, e.g. voice samples, that are formatted and to which a data frame header is added. The method includes attributing codec categories to each of the data or voice frames according to the codecs by means of which the data samples are generated, each codec category corresponding to a different mouth-to-ear delay budget range for the data frames; sorting the data frames according to their codec categories; generating multiplexed cells from data frames of a same codec category, each multiplexed cell being obtained by multiplex aggregation of a predetermined number of voice samples; and transporting the multiplexed cells from an ingress router to an egress router in the IP-network.
