In Renhe District of Panzhihua City, the intelligent system supporting the hazard‑removal and reinforcement project of Yuejin Reservoir has been successfully completed. To ensure the efficient and stable operation of critical functions such as reservoir safety monitoring, video surveillance, and dispatch communication, the project selected Guangwangshi’s high‑performance 10‑gigabit Layer‑3 network solution, creating a smart water‑resources communication platform that delivers high bandwidth, easy management, and exceptional reliability.
Project Challenges: Building a High‑Performance, Highly Reliable Service‑Carrying Network
Business Drivers: The system must reliably carry dam safety monitoring data, multiple streams of high‑definition video surveillance, internal voice communications, and future smart‑water applications, with stringent requirements for core link bandwidth.
Centralized Management: With network devices distributed across various functional areas, the solution must support unified remote configuration, monitoring, and operations to reduce management complexity.
Stability First: Although primarily deployed in indoor server rooms and low‑voltage equipment rooms, the equipment must maintain excellent stability and reliability to ensure 24/7 uninterrupted service.
Simplified Deployment: A large number of front‑end IP cameras require centralized power supply via Ethernet cables to streamline cabling and improve project efficiency.
Guangwangshi’s High‑Performance Layer‑3 Network Architecture
Based on these requirements, Guangwangshi provided a network solution centered around 10‑gigabit connectivity and flexible PoE access.
Network Core Layer: High‑Performance 10‑Gigabit Switches
A high‑performance 10‑gigabit core Layer‑3 managed switch from Guangwangshi was deployed at the project’s main monitoring center.
The device features 12 Gigabit electrical ports, 28 Gigabit SFP optical ports, and 4 10‑Gigabit SFP+ optical ports, delivering robust data switching and processing capabilities.
Its comprehensive L3 routing functions, dual‑stack IPv4/IPv6 support, and dynamic routing protocols provide a flexible and efficient communication foundation for all reservoir‑related systems.
Service Access Layer: Intelligent PoE and 10‑Gigabit Uplinks

Its comprehensive L3 routing functions, dual‑stack IPv4/IPv6 support, and dynamic routing protocols provide a flexible and efficient communication foundation for all reservoir‑related systems.
Network Intelligence and Reliability
The entire network supports ERPS ring protocol (convergence time < 20 ms) and redundancy protocols such as MSTP, enabling rapid self‑healing when links fail and ensuring continuity of critical services.
Through well‑designed VLANs, ACL access control lists, and QoS traffic policies, the system achieves logical isolation of business functions and prioritizes the transmission of critical data—such as safety‑monitoring signals.
Unified web‑based management, CLI command line, and SNMP network management protocols allow convenient centralized remote management and intelligent operations for all devices.
Key Features and Value of the Solution
High‑Performance Service Carrying: The 10‑gigabit core and uplink architecture provides ample bandwidth for current and future smart‑water applications, completely eliminating bottlenecks caused by video stuttering and data latency.
Intelligent Operations and Maintenance: Comprehensive Layer‑3 management capabilities enable operators to easily perform network planning, policy deployment, status monitoring, and fault diagnosis, significantly boosting operational efficiency and reducing long‑term operating costs.
Flexible and Streamlined Deployment: The use of PoE power delivery eliminates the need for separate power cabling for many front‑end devices, simplifying installation and shortening the overall project timeline.
Stable and Reliable Performance: Equipped with a mature, reliable commercial architecture, the devices deliver sustained, stable operation in standard server room environments, providing a solid network foundation for all critical reservoir functions.
Project Outcomes
Since going live, the network system has operated stably and efficiently, successfully integrating the reservoir’s monitoring, surveillance, and communication systems onto a single high‑performance platform. Real‑time data transmission is accurate and error‑free, high‑definition video streams load smoothly, and comprehensive situational awareness along with intelligent management of reservoir operations have been achieved, meeting the project’s intended construction goals.
The head of the project information center commented: “We needed a network system capable of reliably supporting diverse services while remaining easy to expand and manage in the future. Guangwangshi’s solution precisely addressed these core requirements; its hardware performance and practical network management features left a deep impression on us—a truly satisfying collaboration.”
