The invention relates to a buffer acceptance method. Such a buffer acceptance method is used for deciding whether to accept incoming data (P-VCi) of a data flow in a buffer (BUF). The buffer (BUF) is dynamically shared by data of a plurality of data flows. The incoming data (P-VCi) comprises a priority (P2) out of at least two priorities (P1, P2). The method comprises the steps of associating for each data flows and to each priority at least one predetermined partial buffer threshold (PBTi2) and at least one predetermined global buffer threshold (GBTmin, GBTmax). Upon reception of the incoming data (P-VCi), its related data flow (VCi) and its priority (P2) is determined. Furthermore, a first monitoring of an actual occupation level of a partial buffer part (qi), being associated to the data flow, against the associated predetermined partial buffer threshold (PBTi2) is executed and a second monitoring of a globaR occupation level of the buffer (Q) against the predetermined global buffer threshold (GBTmin, GBTmax) being associated to the data flow (VCi) and to the priority (P2) is executed. Finally, the method comprises denying acceptance of the incoming data (P-VCi) in the event when both monitoring tests are providing a drop result i.e. the first monitoring provides a first drop result and the second monitoring provides also a second drop result.
