A Device Information-Centered Accelerator Control Network Management System

Purpose The control network is a critical infrastructure that supports the stable operation of the accelerator. Each device accessing the control network has different device information, such as IP address, MAC address, connected switches and ports, device location and purpose. Accurately maintaining the mapping relationship between these device information facilitates network management. It helps inventory assets, fault location and provide visibility into dynamic changes of device on the network. However, existing tools cannot fully satisfy these demands. They only map some information and lack details important for accelerator facilities like device location and purpose. Additionally, they only reflect the current status rather than indicating dynamic changes across all devices over time. As intelligent devices proliferate, the scale of the control network is rapidly expanding, posing greater challenges in maintaining mapping relationships. Methods This paper proposes a device information-centered Accelerator Control Network Management System (ACNMS). It establishes a device information management framework and allows network administrators to perceive the dynamic changes of devices on the network. The system adopts a layered architecture. Back-end modules implement the core logic of all functions. The graphical user interface presents data and provides a management portal. Results The system test on the control network of the National Synchrotron Radiation Laboratory demonstrates that it can meet the functional design objectives. The application scenarios of the ACNMS are further expanded through system integration and combination with network automation. Conclusion The ACNMS has proven to be an efficient network management tool that significantly improves the operation and maintenance efficiency of the accelerator control network.
