Abstract Because a general Hash algorithm had high collision rate and was not controlled while be used to flow match-ing,a stochastic matrix mapping Hash algorithm was presented,in which the elements of a large set were mapped into a small set through a pre-choosing stochastic number matrix.Tests show that the algorithm has high operation speed,high storage utilization rate and low collision rate,its flow matching speed is up to 2 million packets per second and it supports 50000 matching rules.
