Access control for buffer

摘要

In a buffer store (MEM2), data packets (D1, D2) are stored which are in each case allocated to one of at least two classes of priority (P1, P2). If the occupancy level (MEMS) of the buffer store (MEM2) exceeds a threshold value, there being such a threshold value for each class of priority, the data packets of the corresponding class of priority are no longer written into the buffer store (MEM2) (so-called "Partial Buffer Sharing"). The invention is characterised by the fact that one or more threshold values are dynamically controlled in order to ensure a lower loss probability for data packets which belong to a high class of priority (P1).
