Application of Industrial Switch in OT Network - houshinetwork/industrial-switch GitHub Wiki

Industrial switches play an important role in OT (Operational Technology) networks and are widely used in the field of industrial automation. OT networks are networks used to monitor and control physical processes, such as those used in industries such as manufacturing, energy, and transportation.

The Industrial switch is used to establish and manage the communication network in the industrial control system. In industrial automation and control systems, various sensors, actuators, controllers, and other devices require data exchange and communication through networks. The Industrial switch acts as the central node of the network and is responsible for transmitting data from the source device to the target device to achieve efficient and reliable communication between devices.

At the same time, the reliability and stability of Industrial switches are also indispensable reasons in OT networks. Industrial environments often face strict working conditions, such as high temperature, humidity, electromagnetic interference, etc., which pose higher requirements for network equipment. The Industrial switch has been specially designed and protected, and has the functions of shock resistance, anti-interference and dust prevention, which can continue to operate stably in harsh industrial environments.

The following are some aspects of the application of Industrial switches in OT networks:

  1. Provide reliable network connection: Industrial Ethernet switch can provide high reliability and low delay network connection to ensure the transmission of real-time data and the reliable execution of control commands. Compared with traditional industrial network equipment, Industrial switches have higher bandwidth and faster data transmission speed, which can meet the requirements of real-time control and sensor data transmission. This is very important for industrial applications that require processing large amounts of data and high real-time requirements, such as industrial robot control, IoT device management, etc.

  2. Support WAN and LAN connection: Industrial switches can connect devices and systems distributed in different geographical locations, and support communication between WAN and LAN. This enables data sharing and centralized management across multiple factories or regions.

  3. Network segmentation and isolation: The Industrial switch can segment the network into multiple VLANs and provide isolation for each VLAN. This helps to improve the security and performance of the network, preventing interference and conflicts between different devices.

  4. Support load balancing and redundancy: Industrial switches can achieve load balancing, distribute network communication load evenly across multiple links, and improve network throughput and availability. In addition, the Ethernet switch also supports redundant network design to reduce the impact of Single point of failure on the system.

  5. Support industrial protocols and communication: Industrial switches support various industrial protocols and communication standards, such as Modbus TCP, PROFINET, EtherNet/IP, etc. This makes connecting and integrating communication between different vendors and devices simpler and more reliable. This compatibility makes Industrial switches an important part of modern industrial networks and can meet the needs of different industries and applications.

  6. Provide network management and security functions: Industrial switches usually provide rich network management and security functions, such as remote configuration and monitoring, virtual private network (VPN) support, access control list (ACL), etc. This helps simplify network management tasks and improve network security.

To sum up, Industrial switches have important applications and positions in OT networks. They not only provide reliable network connectivity and data transmission, but also support critical industrial applications and systems, and provide key functions such as network segmentation, load balancing, and security, meeting the requirements of the industrial automation field for networks.
