Introduction With the continuous development and popularization of network technology, network products have penetrated into every corner of people's daily lives. However, the energy consumption of these products has gradually become an important issue. Especially for network interface cards in network equipment, they often remain active to transmit data, thus consuming a lot of electricity in the long run. In response to the global call for environmental protection and energy saving, it is imperative to explore energy-saving technologies for network interface cards. II. Overview of Network Interface Cards in Network Products The network interface card (NIC), also known as a network interface controller or network adapter, is a key component in network communication, mainly responsible for data transmission and forwarding between network nodes. It is usually installed on the motherboard of a computer or server in the form of an integrated or add-on board, playing an important role.

III. Analysis of Reasons for Energy Consumption of Network Interface Cards The main function of the network interface card leads to its long-term operation and high energy consumption. The reasons include but are not limited to: firstly, continuous workload during the transmission process will increase power consumption; secondly, the equipment remains on for a long time, resulting in unnecessary power waste; thirdly, the electrical signal conversion and amplification involved in the data transmission process also consume a certain amount of energy. IV. Exploration of Energy-Saving Technologies To solve the problem of high energy consumption of network interface cards, we can start from the following aspects: 1. Energy-saving algorithms: Improving the energy-saving algorithm inside the network interface card can effectively control its power consumption under different circumstances. For example, it can automatically enter a low-power mode during idle periods to reduce energy consumption. 2. Energy-saving chips: Replacing high-power chips with low-power chips is also one of the effective means to reduce equipment's running power consumption, as well as reducing cooling pressure and noise. 3. Network management optimization: By optimizing the management of network traffic, the transmission frequency and volume of network interface cards can be reduced, thereby reducing their power consumption. 4. Green power technology: Using a more efficient power management system can more accurately control the power requirements of the network interface card. Furthermore, improving the power supply efficiency can reduce overall energy consumption. V. Application and Future Outlook of Energy-Saving Technologies The various energy-saving technologies mentioned above have been widely used in various network products at home and abroad. At the hardware level, various new chip
