Abstract: In a method for network communications, a session management network element receives an identifier of a session of a terminal device, an identifier of a port corresponding to the session, and a processing policy of a data flow for the port. The session management network element determines, according to the identifier of the port, a type of a first device corresponding to the port. The session management network element then sends, according to the determined type of the first device, processing policy information to the first device. The processing policy information comprises the identifier of the port and the processing policy of the data flow.
