A network management system (NMS) serves to monitor, control, and manage network infrastructure. Its primary purpose is to ensure network performance, availability, and security, allowing for proactive troubleshooting and configuration. NMS helps in identifying issues, optimizing resources, and maintaining compliance with policies. By providing real-time insights and alerts, it enables network administrators to maintain operational efficiency and enhance user experience. Ultimately, the system plays a vital role in ensuring that network services are reliable and responsive to both internal and external demands.
