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:
A camera control method, user equipment (UE), and a camera where the camera control method includes sending a detection request message to an Internet Protocol (IP) multimedia subsystem (IMS), where the detection request message includes a detection instruction, where the detection instruction is used to instruct, after the IMS forwards the detection request message to the camera, the camera to send a detection response message carrying device information to the UE using the IMS according to the detection instruction, receiving the detection response message returned by the IMS, and displaying corresponding parameter information and function keys according to the device information of the camera included in the detection response message.
Abstract:
The present disclosure relates to operation, administration and maintenance (OAM) data transmission methods and apparatuses. One example method includes obtaining, by a first node, a first data flow of a client. The first node inserts an OAM data block in the first data flow of the client to obtain a second data flow of the client, where the OAM data block is a 64B/66B code block that carries OAM data. The first node distributes the second data flow of the client to at least one slot of a channel corresponding to the client.

Abstract:
A method includes: sending a first boundary bit block; sequentially sending an Ith bit block; determining a first parity check result and a second parity check result, where a check object of the first parity check result includes m consecutive bits of each bit block in the N bit blocks, a check object of the second parity check result includes n consecutive bits of each bit block in the N bit blocks, and at least one of m and n is greater than or equal to 2; and sending a second boundary bit block, the first parity check result, and the second parity check result.

Abstract:
This disclosure relates to a data transmission method, apparatus, and system, and belongs to the field of communications technologies. The data transmission method includes: obtaining, by a first node, m (m≥2) first FlexE clients, mapping the m first FlexE clients to one second FlexE client, and transmitting data of the second FlexE client to a second node, where data of each first FlexE client occupies a fixed timeslot of the second FlexE client, and the second node is different from the first node. In this disclosure, a problem in a related technology that a relatively fine granularity of a FlexE client imposes a relatively strict requirement on data processing performance of a node is resolved, and a plurality of first FlexE clients are mapped to one second FlexE client.

Abstract:
A method applicable to a commonest application scenario, the method includes: an AR receives a first packet sent in a unicast manner by a CGN. The first packet includes information for indicating Restart announce, the first packet's source address is the CGN's address, and the first packet's destination address is the AR's address; AR changes the first packet's destination address to an address of a CPE connected to the AR, to obtain a second packet, where the AR and the CPE are connected by using a Layer 2 network, and the CPE's address is a multicast address; and the AR sends the second packet. The method is used for quickly informing, after the CGN restarts or undergoes an active/standby switchover, the CPE that an exception occurs, for example, the CGN restarts or undergoes an active/standby switchover, so that a CGN has relatively small load when recreating NAT mapping.
