Abstract: A method includes extracting packet information of a data packet to be transmitted through a Transmission Control Protocol (TCP) connection. If the packet information does not match information in a first data flow table, a first compliance detection is performed on the data packet. A state machine of the TCP connection is obtained if the first compliance detection is successful. The method also includes recording the packet information in the first data flow table, recording a connection status of the TCP connection in a first connection tracking table, and sending the data packet to a receiving end of the TCP connection. If the packet information matches the information in the first data flow table, a second compliance detection is performed on the data packet and, if the second compliance detection fails, the connection status of the TCP connection is adjusted and the data packet is discarded.

Abstract: A packet processing method and a related apparatus are provided. The method includes: obtaining a first packet including first indication information, wherein the first indication information is used to indicate a data flow corresponding to the first packet; determining a target flow entry in an integrated flow table based on the first indication information, wherein the integrated flow table includes at least one flow entry, each flow entry includes a unified match entry and a comprehensive behavior entry, the unified match entry uniquely identifies a data flow, a unified match entry of the target flow entry identifies the same data flow as indicated by the first indication information; and performing an operation on the first packet based on a comprehensive behavior entry included in the target flow entry.
