Introduction
To boost regional economic development and facilitate cross-border logistics between China and the ASEAN region, a major transit line highway project required a robust Upgrade. The core of this modernization was a Smart Highway Surveillance System designed to ensure traffic safety and operational efficiency. Maisvch provided a highly reliable, 10-Gigabit industrial network backbone utilizing over 400 industrial Ethernet switches, ensuring seamless data transmission for real-time monitoring under harsh outdoor conditions.
The Challenges
The highway environment presents unique challenges for network equipment. The project owners established strict criteria for the communication network:
1. High Availability & Network Redundancy
Given the critical nature of highway safety, network downtime is not an option. The system required a Ring Topology architecture to ensure that if a single point of failure (cable break or device failure) occurred, the network would self-heal instantly (milliseconds recovery time) to prevent data loss.
2. Advanced Network Security
With the rise of cyber threats in critical infrastructure, the network required comprehensive security features. This included:
- VLAN Isolation: To separate video data from control data.
- ACL (Access Control Lists): To filter unauthorized traffic.
- Port Security (MAC Binding) & 802.1X Authentication: To prevent illegal device access at remote roadside cabinets.
3. Industrial-Grade Ruggedness
The equipment would be installed in roadside cabinets subject to extreme weather. The devices needed to operate reliably in temperatures ranging from -40°C to 75°C and meet strict Industrial EMC standards to resist electromagnetic interference from passing heavy vehicles and power lines.
Solution Maisvch
To meet these rigorous demands, Maisvch deployed a comprehensive industrial networking solution comprising approximately 400 units of managed industrial Ethernet switches.
1. 10-Gigabit Backbone for Massive Data
The network utilizes a multi-ring architecture. At the core and aggregation layers, Maisvch Layer 3 10-Gigabit switches were deployed. This high-bandwidth backbone ensures that the massive throughput generated by hundreds of HD cameras and sensors is transmitted to the control center with low latency and no video lag.
2. Robust Safety and Reliability
The deployed switches support Maisvch’s proprietary fast ring redundancy protocol. In the event of a fiber cut along the highway, the network recovers in under 20ms. Furthermore, the robust cybersecurity features (802.1X, ACLs) effectively locked down the network edge, ensuring only authorized cameras and sensors could communicate with the central server.
3. Seamless Integration
The solution successfully integrated data from video surveillance, traffic detectors, and environmental sensors into a single, unified Ethernet network. This allows the operations center to visualize traffic conditions in real-time, respond to accidents faster, and optimize traffic flow.

Résultats
The deployment of the Maisvch industrial network infrastructure has delivered immediate and tangible benefits to the highway’s operation management:
- Uninterrupted Surveillance Coverage: With approximately 400 industrial switches operating stably, the control center now maintains 24/7 visibility over the highway. The redundant ring topology has proven resilient, ensuring zero data loss even during network maintenance or link fluctuations.
- Enhanced Operational Efficiency: The high-bandwidth, low-latency 10GbE backbone successfully supports the real-time transmission of uncompressed HD video streams and sensor data. This capability allows operators to detect accidents, congestion, or road hazards instantly, significantly reducing incident response times.
- Strategic Logistics Support: By ensuring a safe and intelligent flow of traffic, the system efficiently supports the high volume of cross-border logistics, fulfilling the project’s economic objectives.
- Future-Ready Infrastructure: The robust network architecture provides a solid digital foundation for future expansions, including V2X (Vehicle-to-Everything) communication and autonomous driving support, without the need for hardware replacement.
