A system/method searches a traffic stream for a sequence of “matching” packets that exhibit a high degree of correlation or similarity to a sequence of “reference” packets. The correlation between matching and reference packets is based on a degree of correspondence between individual packets, as well as the sequence-order of the corresponding packets. A variation of the Needleman-Wunsch algorithm is preferably used to select corresponding packets in the traffic stream that provide a sequence-order that best matches the sequence-order of the reference packets, based on a measure of the correspondence for each match, and a penalty associated with each non-match. The algorithm is further modified to reduce the required search-space for finding corresponding packets in the traffic stream.
