Abstract
Processing of packets in a stream of packets where the packets are assigned with sequence numbers is disclosed. Packets are distributed into at least two analysis windows based on predetermined N lowest bits of the sequence numbers, wherein an analysis window includes M lowest bits of the sequence numbers, M being an integer greater than N. N+1 to M lowest bits of the sequence numbers are analyzed in at least one of the analysis windows while ignoring the N lowest bits to determine the ordering of the packets. A packet is determined as suspicious in response to the analysis indicating the packet being in an incorrect position.
