Abstract: A network attack defense policy sending method and apparatus are presented. The method includes receiving attack information which includes a target Internet Protocol (IP) address, and the attack information is used to indicate that a network attack packet whose destination address is the target IP address exists in a first network; determining that the network attack packet enters the first network through a first edge network device, where the first edge network device is an edge device in the first network; sending a defense policy to the first edge network device, where the defense policy is used to instruct the first edge network device to process, according to the defense policy, a packet whose destination address is the target IP address. By means of this application, network resources occupied by a network attack packet can be reduced, and an effect of defending against the network attack packet can be improved.

Abstract: A data packet extraction method and apparatus is disclosed. Two hash values calculated based on quintuple information of different data packets of a same session are 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 sampling remainder, all the data packets in a network that belong to the session are extracted, so as to implement data packet extraction based on a session. When the quintuple information of the different data packets of the same session matches a first mapping table, 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 as to implement data packet extraction based on a session.
