Abstract
A switching device comprising at least one ingress port and at least one egress port. The switching device is arranged to receive data packets through the at least one ingress port and to forward received data packets to respective ones of the at least one egress port. The switching device further comprises a primary buffer arranged to store data packets received via at least one of the least one ingress ports and a secondary buffer associated with the primary buffer. The switching device is adapted to select a data packet from the primary buffer and if but only if the secondary buffer satisfies a least one first predetermined criterion, transfer the selected data packet to the secondary buffer.
