An Ethernet communication method, device and equipment

Abstract

Embodiments of the present application provide an Ethernet communication method, device, and equipment, which can be applied to electric vehicles, and can be applied to the field of automatic driving or intelligent driving. The method includes: the first device sends a time parameter to the second device, the The time parameter includes the duration of the quiet state, the duration of the refresh state, or at least one of the parameters of the total duration, the total duration being the total duration of the quiet state and the refresh state; the first device adjusts the LPI mode according to the time parameter Status duration. The solution provided in this embodiment can be applied to communication systems, such as vehicle outreach V2X, vehicle-to-vehicle communication long-term evolution technology LTE-V, vehicle-vehicle V2V, Internet of Vehicles, MTC, IoT, LTE-M, M2M, Internet of Things, etc. The application can improve the energy saving effect and avoid the waste of bandwidth and energy.

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 for 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, a...

AI Technical Summary

Problems solved by technology

[0004] In the current technology, since the sending and receiving end devices operate at a transmission rate, the time of each state is fixed. For sporadic data transmission, when the sending end device and the receiving end device enter or exit the LPI mode, they experience sleep and wake-up states. It consumes a lot of bandwidth and energy, which is easy to cause waste of bandwidth and energy
