Problems solved by technology

In time-sensitive networks, the IEEE 802.1Qbv protocol and the guard band mechanism mainly guarantee the deterministic service of time-sensitive flows, and use the first-in-first-out (FIFO) principle for communication for best effort flows (Best Effort, BE), resulting in Waste of best-effort flow slot bandwidth resources
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention provides a data transmission method and device based on a time-sensitive network and electronic equipment, and relates to the field of data processing, in particular to the technical field of network communication. According to the specific implementation scheme, in response to a data sending instruction, a current BE frame set corresponding to the data sending instruction is obtained, and the data sending instruction is an instruction generated when BE frames need to be sent every time in the current transmission period of the time-sensitive network; determining the residual time slot length of the time-sensitive network in the current transmission period; based on the residual time slot length, a target BE frame in the current BE frame set is determined, and the bandwidth utilization rate corresponding to the target BE frame meets a preset condition; and sending the target BE frame. When the data sending instruction is responded, time sequence rearrangement is performed according to the bandwidth utilization rate maximization model when each preset BE frame is sent, so that the best effort flow time slot is utilized to the maximum extent, and the problem of bandwidth resource waste caused by introduction of a guard band mechanism in related technologies is solved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, in particular to the technical field of network communication, and in particular to a time-sensitive network-based data transmission method, device, electronic equipment, and storage medium. Background technique [0002] Time Sensitive Network (TSN) is a communication technology that is being actively promoted by the international industry. It is based on standard Ethernet, through high-precision time synchronization, traffic shaping, path control, resource reservation and business A series of key technologies such as scheduling provide reliable data transmission guarantee for real-time sensitive services, and are widely used in industrial control, vehicle network, aerospace and other fields, so the research on time-sensitive networks is of great significance. In time-sensitive networks, the IEEE 802.1Qbv protocol and the guard band mechanism mainly guarantee the deterministic se...
