Abstract: A method for controlling a transmit power of a terminal, and a terminal, where the method and the terminal include, working states of a first antenna and a second antenna may be monitored, and then a transmit power of the first antenna or that of the second antenna may be controlled according to a preset correspondence. Therefore, according to the method and the terminal, a transmit power of an antenna in a working state in the first antenna and the second antenna may be accurately controlled. If the transmit power is less than a standard transmit power, a Specific Absorption Rate (SAR) can be reduced.

Abstract: This application discloses a method and an apparatus for updating a manner of processing a packet of a service flow. The method includes a first packet of the service flow is forwarded by using a first service function chain (SFC). A control node obtains a flow identifier and indication information from a service function (SF) node of the first SFC, where the indication information is used to indicate a manner of processing a second packet of the service flow, the flow identifier is used to identify the service flow. The control node obtains the manner of processing the second packet according to the indication information, and sends the flow identifier and the manner of processing the second packet to the processing node, where the manner of processing the second packet does not include forwarding the second packet along the first SFC.

Abstract: The present disclosure provides a message forwarding method and system, and a relay agent device. The forwarding method includes: receiving a first DHCPv6 message from a DHCPv6 client through a layer-3 interface; generating a Relay-forward message, where the first DHCPv6 message is encapsulated into the Relay-forward message and an identifier of the layer-3 interface is added therein; and sending the Relay-forward message to a DHCPv6 server.

Abstract: The present invention is applicable to the field of PONs and provides a PON protection method and apparatus. A first transmission path is established between a first OLT and a far-end network node, and a second transmission path is established between a second OLT and the far-end network node. When it is found that a fault occurs on an optical path of the first OLT, a PON port corresponding to the optical path is switched to a corresponding PON port on the second OLT, and a fault notification is sent to the far-end network node. After receiving the fault notification, the far-end network node switches a data flow of the PON port corresponding to the optical path from the first transmission path to the second transmission path.
