Ethernet switch and port polling system and polling method thereof

Abstract

The invention relates to the field of Ethernet switch energy saving, and particularly relates to an Ethernet switch and a port polling system and a polling method thereof. A first timer is arranged to carry out timing for the ports of a switch in a polling way, a processor reads the connection state of the current timing port within the time of port polling timing, and therefore, opening and closing of the sending and receiving function of the ports can be controlled according to the connection state of the ports at the end of port polling timing, and energy saving control on the switch is realized. Meanwhile, a second timer is provided to control the polling frequency of each port of the switch, so that opening and closing of the sending and receiving function of the ports can be controlled at appropriate time according to the connection state of the ports. Therefore, real-time demand of the normal functions of the ports can be effectively ensured while energy saving control is achieved.

Description

technical field

[0001] The invention relates to the field of energy saving of Ethernet switches, in particular to an Ethernet switch and its port polling system and polling method. Background technique

[0002] The energy-saving design of industrial equipment is an extremely frequently used and highly respected technology. Due to the differences in industrial Ethernet switch equipment and functional requirements, the energy-saving methods adopted also have their own characteristics. In the field of switch energy saving, it is widely used that the switch detects its network traffic in real time, starts a timer when the detected network traffic is empty, and automatically cuts off the power of the switch when no network traffic is detected when the timer expires. This intelligent power-off energy-saving method with a timer can effectively prevent the user from frequently turning on or off the switch during normal use. However, although this method of energy saving by cutting ...
