Abstract: This embodiment provides a user packet forwarding control method and a processing node. A processing node receives a processed user packet sent by a first target value-added server (VAS), and the processing node correspondingly generates a target processing identifier according to the processed user packet, so that the processing node determines, according to the target processing identifier, that the user packet has been processed by the first target VAS. Each processing node can determine VASs that have processed the user packet, without the need to change the original user packet, thereby effectively ensuring that each VAS provides a normal value-added service to the user packet, and avoiding a fault in a process of forwarding the user packet between value-added servers.

A control circuit of the linear regulator includes a feedback network having an input coupled to the output voltage node and an output configured to generate a feedback voltage. An error amplifier receives a reference voltage and the feedback voltage to generate an error signal.

A first power supply terminal of the driver circuit is coupled to a first power supply node and a second power supply terminal of the driver circuit is coupled to the output voltage node. The bias current for operation of the driver circuit is accordingly directly sourced to the output voltage node to support low quiescent current operation of the regulator circuit.
