Abstract
The invention relates to a method and apparatus for scheduling transmission-link capacity between packet-switched telecommunications flows, in such a way that it is possible to guarantee that packets representing delay-critical traffic will be scheduled to the transmission link (S) before packets representing non-delay-critical traffic and, in addition, that it is possible to limit the joint transmission speed of specific service-quality classes of an individual customer flow. The invention is based on the service-quality classes being separated into two different categories: a service-quality-class based scheduling branch (C) and a customer-flow based scheduling branch (F). When selecting the next packet to be forwarded, one of the two said branches (C or F) is selected and in the service-quality-class based scheduling branch a service-quality class (CoS) is selected and, within the selected service-quality class, a customer flow (CF) is selected and in the customer-flow based scheduling branch a customer flow (CF) is selected and, within the selected customer flow, a service-quality class (CoS) is selected.
