In the complex network architecture of industrial automation and intelligent manufacturing,
industrial routers are the core hubs that ensure the interconnection of devices and the flow of data. Unlike civilian routers, Xinghengxun industrial routers are tailor-made for harsh industrial environments. They not only enable the interconnection and interoperability of multiple types of networks but also ensure the precise and efficient transmission of data in complex industrial scenarios, laying a solid communication foundation for industrial production lines, 5G private networks and other scenarios.
In industrial production environments, various types of equipment often belong to different network segments or types, such as serial port devices, network port devices, 5G/4G wireless devices, etc., and there are inherent barriers to data intercommunication. The core function of Xinghengxun industrial routers is precisely to break down these barriers and build a unified and stable industrial communication network.
First, cross-network/network segment interconnection and data "translation". The Xinghengxun industrial router can connect to various types of networks or network segments such as wired, 5G/4G, and serial ports, acting as a "data translator" between different networks. It converts and ADAPTS data of different protocols and formats, enabling devices that were previously unable to communicate directly (such as RS485 serial port PLCS, Gigabit network port sensors, and 5G smart terminals) to achieve data intercommunication Form an integrated network covering the entire production line.
Second, intelligent routing and forwarding. As the core node of the industrial network, the Xinghengxun industrial router will plan the optimal transmission path for data packets based on preset rules and real-time network status, ensuring that data is accurately and efficiently delivered to the destination. Whether it is the return of control instructions from remote serial port devices, the reporting of massive production data from network port devices, or the cloud interaction of Xinghengxun's own terminals, all can rely on its routing and forwarding capabilities to achieve non-blocking transmission.
Thirdly, it is suitable for industrial-grade environments. In addition to the basic communication functions, the Xinghengxun industrial router also features industrial-grade protection characteristics such as wide-temperature operation, anti-electromagnetic interference, and dust corrosion resistance. It can be adapted to harsh scenarios such as high-temperature workshops, outdoor base stations, and mining areas, ensuring the all-weather stability of the communication link.
The working logic of MovingComm industrial routers is based on the third layer (network layer) of the OSI seven-layer network model. Its data transmission and routing decision-making process mainly revolve around three core links, and at the same time, dynamic protocols are used to achieve intelligent optimization of paths.
Dynamically generate and maintain the routing table
The routing table is the "navigation map" for industrial routers to make path decisions. MovingComm industrial routers continuously learn the real-time structure of industrial networks through their built-in topology-aware mechanism, and dynamically generate and update the routing table. The table will record in detail key information such as the best path to each target network segment and the IP address of the next-hop device. For scenarios where industrial network devices are frequently added or removed, its routing table also supports millisecond-level updates to ensure that the "navigation map" is always accurate and effective.
Route lookup and path determination
When a data packet is received, the Xinghengxun industrial router will first resolve the destination IP address of the data packet, and then perform precise matching in the routing table to quickly lock the next-hop IP for data transmission. This process relies on its self-developed high-speed search algorithm, which can achieve microsecond-level path decision-making and meet the strict real-time requirements of industrial scenarios.
Data forwarding and encapsulation processing
After determining the optimal path, the router will perform targeted processing on the data packet: add the MAC address of the target link to it, decrement the TTL value of the IP packet header, recalculate the data checksum, and then forward the encapsulated data packet to the next-hop device. The entire process not only ensures the integrity of the data but also prevents data packets from circulating infinitely in the network.
MovingComm industrial routers support multiple mainstream routing communication protocols. In scenarios where multiple paths are available, they will follow preset rules (such as path length, link bandwidth, transmission delay, link stability, etc.) to filter the optimal path. Due to the fact that the network segments and device connection status of industrial networks are easily affected by production adjustments and environmental changes, their routing information will be automatically updated regularly as stipulated in the protocol. For instance, in a 5G industrial private network, if the signal of a certain 4G link is interrupted, the router can switch to the 5G link within one second to ensure that data transmission is not interrupted.
The core task of MovingComm industrial routers is to "store and forward" data packets. Its complete workflow can be divided into three stages, each interlinked to ensure the accuracy of data transmission:
Data packet reception and link layer verification
When a data packet arrives at the router interface, the device will first call the corresponding link layer functional module to parse the protocol header, and at the same time activate mechanisms such as CRC cyclic redundancy check and frame length check to verify whether the data has been lost or tampered with during transmission. The Xinghengxun router is also equipped with an industrial-grade data error correction algorithm, which can repair slightly damaged data packets and further enhance data integrity.
IP layer processing and routing matching
After the link layer verification is passed, the router enters the IP layer processing stage: extracting the destination IP of the data packet, completing the path matching in the routing table, and determining the next-hop address. At the same time, perform a decrement operation on the TTL field of the IP header. If the TTL value returns to zero, directly discard the data packet to avoid network congestion. Finally, recalculate the IP checksum to ensure the validity of the IP layer data.
Data packet encapsulation and forwarding
Based on the next-hop information matched, the router encapsulates the protocol header of the corresponding link for the data packet and then sends the data packet out through the designated physical interface. For example, when transmitting data to the cloud, 5G/4G protocol headers are encapsulated. When transmitting to local network segment devices, the Ethernet protocol header is encapsulated.
To intuitively understand the role of the routing table, you can refer to the simple routing table of MovingComm industrial routers (as shown in the following table) :
When the router receives a data packet destined for "Warehouse network Segment 2", it will query the routing table and find that the next hop is SHX-R2. It will then forward the data packet to this device to achieve cross-segment data transmission.
In addition to the basic routing function, the Xinghengxun industrial router is also equipped with a wealth of expansion functions to adapt to complex industrial needs
Access Control：IP whitelist/blacklist can be set to restrict illegal devices from accessing industrial networks and ensure data security.
Network Address Translation (NAT）：Realize public network access for internal network devices while hiding the real IP addresses of the devices to reduce the risk of being attacked.
Data priority queuing：Set high priorities for key data such as production control instructions and safety alerts to ensure their priority transmission and prevent non-critical data from seizing bandwidth.
5G Private network adaptation：In 5G industrial private networks, precise connection of network slices can be achieved, ensuring dedicated transmission channels for different business data, and providing low-latency and highly reliable communication support for scenarios such as industrial remote control and high-definition monitoring.
MovingComm industrial routers, with their clear working logic, stable core functions and rich expansion capabilities, have become key devices in the field of industrial communication. Whether it is the network transformation of traditional industrial production lines or the construction of smart factories under 5G private networks, it can provide a solid guarantee for equipment interconnection and data flow, and help the industrial field steadily move towards digitalization and intelligence.
