Abstract: This application discloses example application instance address translation methods. One example method includes receiving, by a control plane device from a mobile edge cloud control device, an address of a target application instance of an application service accessed by a terminal. The control plane device can then send the address of the target application instance to a first user plane device. The control plane device can then instruct the first user plane device to set, as the address of the target application instance, a destination address of an uplink packet that is of the terminal and is associated with the application service

Abstract: Embodiments of the present disclosure provide an anchor gateway switching method, apparatus, and system. The method includes: determining, by a control plane (CP) device, to switch a source anchor gateway; obtaining, by the CP device, location information of a terminal; determining, by the CP device, a target anchor gateway based on the location information; and sending, by the CP device, a modification request message to an software defined network (SDN) controller, where the modification request message includes an identifier of the terminal and an identifier of the target anchor gateway, the modification request message is used to notify the SDN controller to: update, based on the identifier of the terminal and the identifier of the target anchor gateway, a forwarding flow table corresponding to a downlink packet, and send an updated forwarding flow table to an SDN switch
