Problems solved by technology

[0002] Network topology refers to the connection relationship between various network nodes in a communication network. These network nodes include routers, switches, bridges, hubs and terminal hosts, etc. In the existing ring network topology system, data passes through the ring The multi-level transmission of each node in the network topology system realizes the forwarding of data in the entire network. However, in the ring network topology system, there may be a node that receives the data sent by it, which may become the traffic of the network node. Too large, causing network congestion
[0003] For the above problems, the existing technology proposes a solution, setting the network traffic threshold of the node, and when the node’s network traffic threshold is greater than the preset threshold, the message data corresponding to the traffic exceeding the threshold is discarded, resulting in the loss of message data

Abstract

The invention relates to a network topological system and a control method and device thereof. The system comprises a plurality of mutually connected ring topological subsystems. Each ring topological subsystem is provided with a main node as a controller which is used for controlling other transmission nodes in the ring topological subsystem. A main port and a standby port are arranged on the main node and the transmission nodes. When the network topological system is normal, the standby port on the main node is blocked to guarantee the main node not to be congested due to excessive traffic flow; when the network topological system is abnormal, the standby ports are turned on to guarantee the normal transmission of data of all nodes in the network topological system.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a network topology system and its control method and device. Background technique [0002] Network topology refers to the connection relationship between various network nodes in a communication network. These network nodes include routers, switches, bridges, hubs and terminal hosts, etc. In the existing ring network topology system, data passes through the ring The multi-level transmission of each node in the network topology system realizes the forwarding of data in the entire network. However, in the ring network topology system, there may be a node that receives the data sent by it, which may become the traffic of the network node. If it is too large, it will cause network congestion. [0003] For the above problems, the prior art proposes a solution, which is to set the network traffic threshold of the node, and when the node's network traffic threshold is greater...
