In the industrial Internet of Things, the Industrial Lan Switch group ring network is an important network architecture method that can improve the reliability and stability of the network, ensuring the continuity and security of data during transmission. The following will detail how Industrial Lan Switch can form a ring network:

1. Basic Concept of Ring Network

As the name suggests, a ring network refers to a network topology where devices in the network are connected in a ring shape through switches. In this structure, each switch is connected to at least two other switches, forming a closed loop. When a link in the ring network fails, data can continue to be transmitted through other links, ensuring the connectivity and reliability of the network.

2. Steps for Industrial Lan Switch Group Ring Network

2.1 Selecting the appropriate switch

Firstly, it is necessary to select the appropriate Industrial Lan Switch based on actual requirements. Industrial LAN switches usually have higher stability and reliability and can adapt to harsh industrial environments. When selecting, factors such as the number of ports, transmission rate, and management functions of the switch need to be considered.

2.2 Determine the topology structure of the ring network

Determine the topology structure of the ring network according to actual needs and network size. Common ring network topology structures include single ring, multiple rings, etc. The single-ring structure is relatively simple and suitable for small networks; The multi-ring structure is more complex, but can provide higher reliability and redundancy.

2.3 Configure switch parameters

Before organizing the ring network, it is necessary to configure the switch as needed. This includes setting parameters such as the IP address of the switch, VLAN division, and port speed. In addition, it is necessary to configure ring network protection protocols such as RSTP and ERPS to ensure the rapid recovery of network communication in the event of link failure.

2.4 Connecting to the switch

Connect the switches using network cables or optical fibers according to the determined ring network topology. During the connection process, it is necessary to pay attention to the correspondence between ports to ensure the correct transmission of data.

2.5 Test the performance of the ring network

After the connection is completed, a performance test is required for the ring network. This includes testing the connectivity, transmission rate, latency, and other metrics of the network. Through testing, it can be verified whether the stability and reliability of the ring network meet the actual needs.

3. Ring Protection Protocol

When organizing a ring network, some ring network protection protocols are usually used to improve the reliability and stability of the network. These protocols include RSTP fast spanning tree protocol, ERPS Ethernet ring protection protocol, etc.
RSTP: RSTP is a spanning tree protocol used to provide fast convergence in Ethernet. It can quickly switch to a backup link in the event of a link failure, thereby reducing the duration of network interruption.
ERPS: ERPS is a protection protocol designed specifically for Ethernet ring networks. When it detects a link failure in the ring network, it can quickly isolate the faulty link and restore network communication.

4. Precautions

When grouping ring networks, it is necessary to ensure that all switches support the selected ring network protection protocol.
It is necessary to pay attention to whether the number and speed of the switch ports meet the actual needs.
When connecting switches, it is necessary to ensure that the correspondence between ports is correct.
When conducting performance testing, it is necessary to simulate the actual network environment to ensure the accuracy of the test results.
Through the above steps and precautions, it is possible to successfully form a ring network with Industrial Lan Switch, improve network reliability and stability, and provide strong support for the application of Industrial Internet of Things.
