Abstract

The embodiment of the invention provides an Ethernet communication method and device and Ethernet equipment. The method comprises the steps that first equipment sends a time parameter to second equipment, wherein the time parameter comprises a parameter of at least one of a quiet state duration, a refresh state duration or a total duration, the total duration is the total duration of a quiet stateand a refresh state; and the first equipment adjusts the state duration in an LPI mode according to the time parameter. According to the invention, the energy-saving effect can be improved, and the waste of bandwidth and energy is avoided.

Description

technical field [0001] The embodiments of the present application relate to the Ethernet technology, and in particular to a communication method, device, and equipment of the Ethernet in a Low Power Idle (Low Power Idle, LPI) mode. Background technique [0002] In order to solve the energy consumption problem of the Ethernet, the Institute of Electrical and Electronics Engineers (Electrical and Electronics Engineers, EEE) proposed an Energy Efficient Ethernet (Energy Efficient Ethernet) mechanism to realize energy saving of Ethernet devices. [0003] When there is no data transmission, the sending device can send a notification of entering the LPI mode to the receiving device, so as to notify the receiving device to enter the LPI mode. At the same time, the originating device enters a sleep (Sleep) state and transits to a quiet (Quit) state. In the dormant state, the link is completely silent. After the quiet state expires, the originating device enters a refresh state, an...
