There is disclosed a scheduler, and a method, for scheduling a plurality of input flows to an output flow, comprising: means for allocating to each input flow a flow level and a threshold value, the flow level being indicative of the number of bits to be scheduled from the input flow, wherein the value of the flow level relative to the threshold value indicates whether the current scheduling of that input flow is sufficient to meet a necessary throughput for that input flow; means for increasing the value of each flow level by a predetermined amount; and means for selecting the input flow to be scheduled in dependence on the flow having a highest priority of those flows having a flow level greater than the respective threshold level, wherein there is further included means for, if no input flows have a flow level above the respective threshold level, increasing the flow level for each input flow having data to transmit by a second predetermined value.
