ABSTRACT:
The invention relates to a method and apparatus for scheduling transmission-link capacity between packet switched telecommunications flows (L1, L2), in such a way that it is possible to ensure the scheduling of packets representing delay-critical traffic to the transmission link (S) before packets representing non-delay-critical traffic and, in addition, to achieve the desired division of the capacity of the transmission link (S) between different traffic groups. The invention is based on performing the selection in the scheduling in stages, as follows: 1) the packets with the highest priority among the packets being offered are sought and 2) from the sub-group obtained, a final selection is performed using a weighting-factor based scheduling method, in such a way that the same weighting-factor based scheduling process is used to handle the sub-groups representing different priority levels in the consecutive selection situations.
