Abstract

See full text

The present invention relates to a method of operating a scheduler (100) of a crossbar switch (200), wherein said scheduler (100) comprises a tree structure comprising an input stage (IS) with a plurality of entry modules (E.sub.--1, E.sub.--2, . . . ) and at least one decider stage (DS.sub.--1, DS.sub.--2, . . . ), wherein each decider stage (DS.sub.--1, DS.sub.--2, . . . ) comprises at least one decider module (D.sub.--1.sub.--1, D.sub.--2.sub.--1, . . . ), wherein one or more modules (E.sub.--1, E.sub.--2, D.sub.--1.sub.--1, D.sub.--1.sub.--2, . . . ) are connected to a decider module (D.sub.--1.sub.--1, D.sub.--2.sub.--1, . . . ) of a subsequent decider stage (DS.sub.--1, DS.sub.--2, . . . ), wherein a packet reference is forwarded from said input stage (IS) or a decider stage to a subsequent decider stage depending on a forwarding decision that is made in a decider module (D.sub.--1.sub.--1, D.sub.--2.sub.--1, . . . ) characterized by the following steps: providing each packet reference with at least one individual attribute, storing accounting information for each of said modules (E.sub.--1, E.sub.--2, D.sub.--1.sub.--1, D.sub.--1.sub.--2), wherein said accounting information depends on the packet references and/or the individual attribute(s) of the packet references which are processed by the respective module (E.sub.--1, E.sub.--2, D.sub.--1.sub.--1, D.sub.--1.sub.--2), and making the forwarding decision depending on said accounting information.
