Problems solved by technology

However, this technology does not consider the impact of frame size and frame period on load
To sum up, the routing technology that considers both schedulability and reliability is still in the blank stage.

Abstract

The invention belongs to the field of Ethernet routing, and relates to a reliability perception time-sensitive network routing method applied to power data transmission, which comprises the following steps: 1, setting a non-overlapping path group, establishing a probability model, measuring the reliability of a network, and selecting a routing candidate solution according to the probability model; 2, after a candidate solution list is selected, establishing a cost function; and 3, minimizing the cost function through a heuristic method based on an ant lion algorithm, and finding a final routing solution enabling the cost function to be relatively small. The method is suitable for an industrial scene, and compared with a traditional method, the reliability of the routing method is ensured while the schedulability of the routing method is improved, so that the real-time performance of data transmission is ensured.

Description

technical field [0001] The invention belongs to the field of Ethernet routing and relates to a reliability-aware time-sensitive network routing method applied to power data transmission. Background technique [0002] The goal of the power Internet of Things is to realize the interconnection of all things and human-computer interaction in all links of the power system, and form a smart service system with the characteristics of comprehensive state perception, efficient information processing, and convenient and flexible applications. For now, the calculation and analysis capabilities of the power grid are still very lacking. In the overall architecture of the "core-device-edge-network-cloud" of the power Internet of Things, the edge refers to the construction of edge computing capabilities through the deployment of edge computing devices and distributed data centers. Edge computing refers to an open platform that integrates network, computing, storage, and application core c...
