A network monitoring system (60). The system comprises storage circuitry (32) for storing network packet information, wherein the network packet information includes a predicted identifier. The network monitoring system also comprises at least one monitoring circuit (36) coupled to a network (70) along which network traffic flows in a form of packets. The at least one monitoring circuit programmed to perform the steps (44) of receiving a packet communicated along the network and determining whether the received packet is communicated between a source and destination in a first set of network nodes. Each packet in a sequence of communications between the source and the destination comprises a packet identifier that uniquely identifies the packet from all other communications in a flow between the source and the destination. The at least one monitoring circuit programmed to perform the step of, responsive to determining the received packet is communicated between a source and destination in the first set of network nodes, comparing the packet identifier of the received packet to the predicted identifier to determine an identifier deviation between the packet identifier and the predicted identifier for identifying an irregularity in the network traffic.
