Description

Energy saving method and device Technical Field The present application relates to the field of communications, and in particular, to an energy saving method and apparatus. Background In digital communication networks, particularly campus networks, traffic has typical tidal characteristics, e.g., traffic during late night phases is generally much less than the bandwidth provided by the network. Currently, even if there is no traffic in the network, the communication device in the network needs to be in an operating state, for example, a physical layer (PHY) of an ethernet interface, a serializer/deserializer (serdes), an optical module, etc. are still in an operating state, which causes a great deal of waste of power consumption. In an ethernet protocol defined by the Institute of Electrical and Electronics Engineers (IEEE) standard, energy-efficient ethernet (EEE) technology is used to put the physical layer into a Low Power Idle (LPI) mode when there is less traffic to save power consumption of the communication device. The current EEE technology has poor power consumption reduction effect. Therefore, a solution is needed to solve the above-mentioned problems. Disclosure of Invention The application provides an energy-saving method and device, which can effectively reduce power consumption. In a first aspect, the present application provides a method of conserving energy, the method being applied to a first device. The first device may obtain first energy saving indication information, where the first energy saving indication information includes a first energy saving level, and the first energy saving level indicates a first energy saving depth of a multi-segment channel included in a link where the first device sends data to the second device, and the first energy saving depth indicates a first energy saving type of the multi-segment channel. After the first device acquires the first energy saving instruction information, the first device sends the first energy saving instruction information to the second device. Accordingly, after receiving the first energy saving instruction information, the second device may control itself to switch to the first energy saving level so as to operate at the first energy saving level. In the application, the second device can realize channel-level energy-saving control based on the first energy-saving indication information sent by the first device, and can control based on the first energy-saving depth when the energy-saving control is executed for the multi-section channels, so that the finer degree of the energy-saving control is higher, and the effect of reducing the power consumption is better correspondingly. By using the scheme, the power consumption can be effectively reduced. In one possible implementation, the first energy saving type of the first channel of the multi-segment channels includes no energy saving, clock gating, or power gating. Where non-power saving means that the device (including but not limited to power, clock, and other processing circuitry) is in operation, clock gating means turning off the clock, and power gating means turning off the power. In a specific example, the first energy saving instruction information includes first energy saving depths corresponding to all channels in the multi-segment channels, and in this scenario, the first energy saving type indicated by the first energy saving depth may include no energy saving, clock gating, or power gating. In other words, for any one of the multiple segments of channels (e.g., the first channel), the first energy saving type of the first channel may include not saving energy, clock gating, or power gating. In this scenario, the first energy saving depth of all channels in the multi-segment channel may also be used to indicate the state of the multi-segment channel, specifically, for a certain segment of channel, the first energy saving type corresponding to the multi-segment channel is not energy saving, which indicates that the state of the segment channel is an operating state, and when the first energy saving type corresponding to the segment channel is clock gating or power gating, the state of the segment channel is indicated as an inactive state. In one possible implementation, the first energy saving level is used to indicate a first energy saving depth of a channel in the multi-segment channel that is not in operation. In this scenario, the first energy type of the first energy depth indication may include clock gating or power gating. In other words, for any channel of the multi-segment channels that is not operational (e.g., the second channel), the first energy saving type of the second channel may include clock gating or power gating. In one possible implementation, the first energy saving indication information may further include first channel state information for indicating a state of a physical channel to which the first device and the second device are connected.
