High-speed network traffic construction method based on session amplification

The invention discloses a high-speed network flow construction method based on session amplification, which comprises the following steps of: respectively modifying a source IP and a destination IP ofa data packet through analysis and multiple amplification of the data packet; recalculating an IP head check value for the modified data packet, and covering and filling the calculated head check value of the IP protocol into a head check value field of the IP protocol; and performing a series of methods of modifying a source MAC address and a destination MAC address of an Ethernet protocol on the modified data packet. According to the method, high-speed network flow can be provided, data packets originally belonging to one session can still belong to the same session after being copied and modified, meanwhile, the amplification factor required by the method and the device is relatively small, and richer and more real network flow can be provided. 本发明公开了一种基于会话放大的高速网络流量构造方法，通过对数据包的解析、倍数放大，对数据包的源IP、目的IP分别修改；对修改后的数据
