A method for applying a differentiated Quality of Service (QoS) to a payload using ar profile indicator that can identify or be used to identify more than two portions of the payload having different QoS requirements. The profile indicator may be one or more length indicators for indicating the lengths of each portion of the payload, or it may be an index to a table which indicates the lengths of each portion of the payload. The table can be used to map the profile indicator to a number of portions in the packet, the lengths of each portion and a QoS requirement for each portion. The different portions may be formatted according to specifically selected transport formats.
