Abstract: The present invention relates to a data packet processing apparatus located in a value-added-service (VAS) network. A transceiver module of the data packet processing apparatus receives a first data packet; a processing module determines, according to a load status of each VAS instance corresponding to each VAS type in a service chain that the first data packet is to go through, a service path that the first data packet is to go through the transceiver module sends the first data packet carrying a service path identifier to a data packet routing apparatus in the network, to instruct the data packet routing apparatus to route the first data packet according to the service path identified by the service path identifier. Load on each VAS instance is considered to avoid that load on devices in a same VAS type is uneven.

Abstract: A method for providing service is provided. A network slice management system of an operator receives a service request message sent by a control device of a third-party service provider. The service request message is used to request the network slice management system to provide a service, and the service request message carries a service requirement. The network slice management system creates a network slice instance based on the service requirement. The network slice instance is used to provide the requested service. The network slice management system sends a notification message to the control device. The notification message carries an identity of the network slice instance.
