Abstract: The present invention discloses a flow table generating method and apparatus. The method includes: obtaining, by an SDN controller, a user data packet processing manner of a VAS server that is sent by a VAS server information collector; generating a flow table according to service chain information of a user data packet, the user data packet processing manner of the VAS server, and a 5-tuple of the user data packet; and sending the flow table to an SDN switch, so that the SDN switch can send the user data packet to a corresponding VAS server according to the flow table, thereby implementing access of the user data packet to a related VAS server in a case in which a VAS server modifies a 5-tuple of a user data packet.

Abstract: A service routing method includes parsing a received data packet to obtain a service type of the data packet; obtaining a service data routing label according to a correspondence between the service type and the service data routing label, where the service data routing label is used to identify a routing path, and the routing path is used to describe a network path for routing the data packet to a service enabler; attaching the service data routing label to the data packet; and sending the data packet to a switch. According to the service routing method provided in embodiments of the present disclosure, data traffic of a traffic classifier is reduced, and load on the traffic classifier is lightened.
