Abstract: The present invention provides a flow control method and a device. The method includes: obtaining, by a gateway, a data packet of a user; determining N value-added services required by the data packet, where N is a positive integer greater than or equal to 1; modifying a first IP address in the data packet to an Mth IP address in an address sequence, where the first IP address is an IP address of a network server, M is a positive integer greater than or equal to 1, the address sequence is an IP address set allocated by the gateway to the user, and a correspondence exists between an address in the address sequence and a value-added service; sending a modified data packet to a value-added service server corresponding to the Mth IP address, so that the value-added service server corresponding to the Mth IP address performs value-added service processing on the modified data packet; and receiving a data packet on which the value-added service processing has been performed, and modifying the first IP address to the IP address of the network server.
