Problems solved by technology

[0003] However, in the existing ring topology network, only one node can transmit data at the same time, and other nodes are in a waiting state. When there are many devices in the network, the data bandwidth will be allocated among all devices, and the transmission efficiency is low. And there is a risk that a node occupies bandwidth for a long time so that other nodes cannot obtain enough bandwidth
In addition, regardless of the total number of nodes in the ring topology, when there are two or more device failures in the network, the entire topology is physically split, and the integrity of the communication link is damaged, which will inevitably make part of the data transmission impossible.

Embodiment 1

[0083] In the embodiment of the present invention, the ring topology-oriented networking communication structure includes two kinds of nodes: ring nodes and bridge nodes.

[0084] A ring node (Node) is a constituent node of the ring network, a target node for data reception, or a starting point for data transmission. Each ring node includes an A port and a B port, which are connection ports forming a ring network. Both the A port and the B port can receive and send data. It should be noted that, if the data frame is received from the A port, when the ring node forwards the data frame, it forwards the data frame from the B port instead of the A port. Correspondingly, if the data frame is received from the B port, when the ring node forwards the data frame, the data frame is forwarded from the A port instead of the B port. That is, the data flow direction in the ring network is clockwise or counterclockwise. The address of the ring node in the ring network is identified by th...

Abstract

The invention discloses a ring topology-oriented networking communication method and device and a storage medium, which are used for improving the transmission efficiency of networking communication under a ring topology and improving the reliability. The ring topology-oriented networking communication method disclosed by the invention comprises the following steps of: receiving data frames by a first bridge node, determining priorities of the data frames, adding the data frames into a to-be-forwarded queue, and sorting the data frames in the to-be-forwarded queue from high to low according to the priorities; selecting a data forwarding port according to routing configuration, and forwarding the data with the highest priority in the queue to be forwarded to the port; and deleting the sent data frame from the queue to be forwarded. The invention further provides a networking communication device for the ring topology and a storage medium.

Description

technical field [0001] The present application relates to the communication field, in particular to a ring topology-oriented networking communication method, device and system. Background technique [0002] Network topology refers to the physical layout of various devices interconnected by transmission media. Common topologies include star structure, ring structure, bus structure, distributed structure, and so on. Among them, the ring topology refers to a structure in which several nodes in the network are connected end-to-end to form a closed ring. This structure uses a public transmission cable to form a ring connection, and data travels between nodes along one direction in the ring. Transmission, information is passed from one node to another, and the direction of data transmission is fixed. In a ring topology network, multiple nodes can be interconnected without additional equipment. [0003] However, in the existing ring topology network, only one node can transmit da...
