The invention provides a flow classification method and device of a multi-channel process applied to multi-core network equipment. The multi-core network equipment establishes a session with opposite end equipment based on a multi-channel protocol. The session comprises a control connection and at least one data connection. The method comprises a step of extracting a specified message feature from the data message of a data connection bearing, a step of inquiring a preset global inquiry table, and determining a target CPU corresponding to the specified message feature, wherein the global inquiry table comprises a mapping relation between the specified message feature corresponding to the data connection and a CPU which processes the control message of the control connection extracted from the control message which controls the connection bearing, a step of sending the data message to the target CPU such that the target CPU processes the data message. According to the embodiment of the invention, the problem of flow disorder caused by sending the flow of a same session to multiple CPUs for processing in processing the flow of a multi-channel protocol is solved.
