Message distribution method and device based on multiple hashes

The invention provides a message distribution method and device based on multiple hashes. The method comprises the steps of: respectively calculating two hash results by utilizing two hash algorithms,taking a result that a spatial main table is searched by utilization of one hash result as a reference index, and taking a result that a spatial sub-table is searched by utilization of the other hashresult as an auxiliary index correction reference index. The device comprises a first calculation unit, a second calculation unit, a first searching unit, a second searching unit and a third calculation unit; the first calculation unit is used for calculating a hash result A by utilizing a hash algorithm A; the second calculation unit is used for calculating a hash result B by utilizing a hash algorithm B; the first searching unit is used for searching a hash spatial main table by utilizing the result A, so that a search result a is obtained; the second searching unit is used for searching ahash spatial sub-table by utilizing the result B, so that a search result b is obtained; and the third calculation unit is used for judging a conflict condition of the search result a, and calculatinga search destination table item index. According to the message distribution method and device based on multiple hashes provided by the invention, a double-hash search sequence is constructed by utilization of two hash functions; therefore, the conflict is effectively avoided; the distribution time is saved; and the distribution efficiency is increased.
