Abstract: Embodiments of this application provide a control method and an apparatus. The method includes: A radio frequency device sends first information to a control device. The first information indicates an enabling/disabling recommendation for at least one energy-saving feature. The radio frequency device receives an instruction from the control device. The instruction instructs to enable a first energy-saving feature and/or disable a second energy-saving feature, the first energy-saving feature includes at least one energy-saving feature that is recommended to be enabled in the first information, and the second energy-saving feature includes at least one energy-saving feature that is recommended not to be enabled in the first information. According to this application, more energy-saving gains can be obtained when a temperature difference is controlled to be stable and hardware reliability of the radio frequency device is ensured.

Abstract: This application discloses a data sending method and apparatus, and a FlexE switching system. When slice packets received by a sending module include a SOP flag and a EOP flag of a same data packet, it indicates that the sending module receives a complete data packet, and immediately sends data packet slices, or sends the data packet slices after a latency of first preset duration. In this way, a stream inside the data packet is not interrupted, a data sending latency is reduced, and transmission efficiency is improved. When the slice packets received by the sending module include a SOP flag of a data packet but do not include a EOP flag of the data packet, it indicates that the sending module has not received a complete data packet, and then sends data packet slices after a latency of second preset duration longer than the first preset duration.
