Abstract

The invention provides a message transmission method, device and system. The method comprises the following steps that: after receiving a first message, first equipment determines which mode is adopted to send the first message according to a condition satisfied by a first number carried by the first message; when the first number of the first message satisfies a first condition, the second devicedetermines a second period label corresponding to the first period label, and sends the first message to a third device through a period corresponding to the second period label; and when the first number of the first message satisfies a second condition, the second device determines a third period label corresponding to the first period label, and sends the first message to a third device through a period corresponding to the third period label. According to the method, the problem of time delay increase caused by continuous drift accumulation of the clock error can be eliminated, and the congestion problem caused by time delay when the second equipment sends the message can be avoided.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message transmission method, device and system. Background technique [0002] Deterministic network is currently a hot spot in the industry. The demand for deterministic network comes from industrial Internet, smart factory, programmable logic controller (Programmable Logic Controller, PLC) remoteness and cloudification, and also from augmented reality (Augmented Reality, AR) or virtual reality (Virtual Reality, VR) in real-time interaction, remote surgery, tactile Internet and other remote real-time services. Its core is to ensure the end-to-end bandwidth, delay and jitter of the service flow. Deterministic transmission means that the delay and jitter experienced by the message transmission need to meet the preset upper bound on the premise that the message complies with certain burstiness requirements. [0003] In a deterministic network, there is a m...
