1. A method in a packet processing system in a fronthaul network in a radio network, for managing packet dropping in the fronthaul network, the method comprising:
receiving a plurality of data packets for transmission over the fronthaul network, wherein the plurality of data packets comprises radio data;
obtaining first information for the plurality of data packets, wherein the first information is related to transmission of the radio data over a radio access interface in the radio network, wherein the first information comprises an indication of a priority value assigned to a packet of the plurality of data packets, and wherein the priority value is derived from an indication that is related to an effect that dropping each of the plurality of data packets have an efficiency of the radio network; and
responsive to a requirement to decrease a load in the fronthaul network, selecting at least one of the plurality of data packets to drop by applying at least one prioritization rule to the plurality of data packets based on the obtained first information.
