A method for processing a datagram, including receiving an initial fragment of the datagram over a communication link and classifying in an initial classification the initial fragment as a first fragment, a middle fragment, or a last fragment of the datagram. The method further includes receiving one or more subsequent fragments over the communication link, following the initial fragment, and classifying each of the one or more subsequent fragments in respective subsequent classifications so as to find among the subsequent fragments at least one of the first fragment, the middle fragment, and the last fragment of the datagram. Responsive to the initial and the one or more subsequent classifications, a determination is made whether the datagram is completely constituted by the initial fragment and no more than two of the subsequent fragments. The datagram is reassembled responsive to the determination.
