Abstract:
1. A router comprising: at least one buffer memory for intermediate storage of pointers for information packets in at least two different buffer memory areas; and a readout unit for reading out the at least one buffer memory, wherein at least one further buffer memory area is provided in order to store selected pointers; wherein during the reading out of the at least one buffer memory, the at least one further buffer memory area is a preferred readout area compared to the at least two different buffer memory areas, wherein each buffer memory area and each further buffer memory area is used for the intermediate storage of pointers for information packets that belong to a special quality of service class, wherein the selected pointers are pointers whose reactivation time would expire or whose existing presence or entry in a buffer memory area would lead to a filling of the buffer memory area above a threshold value, wherein a first buffer memory area of the at least one further buffer memory area and a second buffer memory area of the at least one further buffer memory area are assigned to different buffer memory-areas of the at least two different buffer memory areas, and wherein the readout unit is configured to read out different buffer memory areas one after the other in predetermined time windows and, before the readout of a buffer memory area, to read out a further buffer memory area assigned to the buffer memory area to be read out, and to read out each temporarily stored pointer in the-further buffer memory area.
