摘要：A data packet extraction method and apparatus is disclosed. Two hash valuescalculated based on quintuple information of different data packets of a same sessionare the same, that is, two calculated remainders are also the same at a same sampling

ratio. When one remainder of the two calculated remainders is a preset samplingremainder, all the data packets in a network that belong to the session are extracted, soas to implement data packet extraction based on a session. When the quintupleinformation of the different data packets of the same session matches a first mappingtable, either all the data packets of the same session can match the first mapping table,or none of the data packets of the same session can match the first mapping table, so asto implement data packet extraction based on a session.
