Abstract:
Pattern matching for a network flow includes storing a representation of the pattern. The representation of the pattern includes hash values representing blocks of data in the pattern. Hash values are calculated for blocks of data in the network flow. The blocks of data are spread across multiple packets in the network flow. The calculated hash values for the blocks of data in the network flow are compared to the hash values in the representation of the pattern to detect the pattern in the network flow.
