There is proposed a speed control method for controlling a link speed of an Ethernet port. The method comprises steps of detecting the amount of data to be sent via the Ethernet port, and controlling the link speed of the Ethernet port based on the detected amount of data. The step of controlling the link speed of the Ethernet port based on the detected amount of data further comprises steps of comparing the detected amount of data with a predefined threshold, and setting the link speed level of the Ethernet port based on the comparison. According to the solutions provided in the embodiments of the present invention, the present invention may set the Ethernet port to a lower speed when there is no large amount of data to be sent, and thus implements power saving without changes to the infrastructure of the Ethernet.
