Abstract
A device may receive a fragment of a fragmented data unit, determine a flow identifier that identifies a data flow with which the fragment is associated, and create a flow entry, based on the flow identifier, to store information associated with the data flow. The device may also determine a fragment key associated with the fragment, store a pointer to the flow entry based on the fragment key, correlate the fragment and another fragment, associated with the data flow, based on the fragment key and the pointer to the flow entry, and accumulate statistics associated with the fragment and the other fragment after correlating the fragment and the other fragment.
