Abstract
The object of the invention is to create a router which has an enhanced processing speed. According to the invention, before access through a readout unit, the pointers for information packets stored in the buffer memory are arranged as required. If an overflow is imminent in a buffer memory area, for example, then individual pointers are selected and removed from the buffer memory area. The selected pointers are shifted into an additional buffer memory area, for example. This additional buffer memory area is then preferentially read out, so that the selected pointers are read out before the pointers in the buffer memory area. The criterion for the selection of a pointer is, for example, an expired reactivation time or a buffer memory area that is filled above a threshold value.
