Embodiment Construction

[0088] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0089] The present invention aims at the problem that the data transmission method in the existing technology has cumbersome operations and cannot meet different delay requirements, and provides a data transmission method, which is applied to the first communication node, such as figure 1 As shown, the method includes:

[0090] Step 11: Determine the forwarding priority of each message data in the current sending queue in the circular queue of the first communication node;

[0091] Step 12: According to the order of the forwarding priority from high to low, send the message data and the corresponding forwarding priority to the corresponding receiving queue in the circular queue of the second communication node; wherein, the forwarding priority is high T...

Abstract

The invention provides a data transmission method and device and a communication node, and the data transmission method comprises the steps: determining the forwarding priority of each message data in a current sending queue in a circular queue of a first communication node; sending the message data and the corresponding forwarding priorities to corresponding receiving queues in a circular queue of a second communication node according to a sequence of the forwarding priorities from high to low; wherein the sequence of the receiving queue corresponding to the data message with the high forwarding priority in the circular queue of the second communication node is before the sequence of the receiving queue corresponding to the data message with the low forwarding priority. According to the scheme, the problems that a data transmission method in the prior art is tedious in operation and cannot meet different time delay requirements are well solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device and communication node. Background technique [0002] More and more applications such as AR (augmented reality) or (virtual reality) VR, precise industrial control, etc. have put forward strict and clear demands on the upper bound, lower bound, or upper and lower bounds (ie, jitter) of network delay. Traditional network The provided "best effort" service capacity is no longer sufficient. [0003] The deterministic network can guarantee the determinism of delay, jitter, packet loss rate, etc., and provide the ultimate network bearer service. Based on this, two schemes are mainly provided in the prior art: the first one is a time-sensitive scheduling method; the second one is a circular queue scheduling method. [0004] For the above-mentioned first solution, the method of time-sensitive scheduling is to control the sending time of...
