Keywords Decompound Hash Algorithm for Quick Flow Classification

This paper proposes a keywords decompound Hash algorithm for quick flow classification based on keywords decompound.It receives the key by decompounding the keywords to small blocks,xored with selected primes and multiplied.Compared D-hash with IPSX,CRC32 and Bob Jenkins Hash algorithms.Experimental results indicate that the algorithm has good capability in rate,well-proportioned keys and collision rate.The classification rate is 18 Mp/s,D-hash can satisfy the quick net flow measurement.
