Network Management System (NMS) is used to monitor and administer the various components of a computer network, such as servers, routers, and switches. A network management system may be installed on any computer for monitoring and managing the entire network.
NMS is an essential tool that helps maintain the health of the overall network in any organization or clusters of networks across the organization. It is vital to carry out various operations within the organization. Network managers must adopt different strategies to effectively maintain a more extensive network, usually from a central computer using NMS. Recording information and communications across computer networks is vital for appropriate network management.
Some NMS platforms are not just for managing networks but also for managing cloud-based services. An NMS is mainly used in large data centers because it is required to keep track of all components on the network, as well as data centers that are connected to them.
For an NMS to keep track of all components on a network, it needs two things: how many devices are connected (or how many computers or users) and what they do (data collection).
The primary purpose of an NMS is to ensure the smooth operation and optimal performance of a network. It enables network administrators to perform various tasks, including:
A Network Management System plays a crucial role in maintaining network stability, security, and efficiency. It simplifies network administration tasks, enhances troubleshooting capabilities, and enables proactive network management to ensure reliable and optimized network operation.
NMS is a broad family of computer software that supports networking devices such as routers, switches, access points, and remote controls. NMS systems are also known as network controllers because they are typically used to manage networks and other aspects of the network.
A Network Management System (NMS) offers several advantages that greatly benefit network administrators and organizations. Here are some key advantages of implementing an NMS:
Centralized Network Control: An NMS provides a centralized platform for managing and monitoring network devices, configurations, and services. It offers a unified view of the entire network infrastructure, allowing administrators to control and troubleshoot network components from a single interface efficiently.
Proactive Issue Detection: NMS tools continuously monitor network devices, interfaces, and services, enabling proactive detection of network issues. Real-time alerts and notifications notify administrators about potential faults, performance degradation, or security threats, allowing them to address problems before they escalate and impact network operations.
Improved Network Performance: By monitoring network performance metrics such as bandwidth utilization, latency, and response times, an NMS helps administrators optimize network performance. They can identify bottlenecks, plan for capacity upgrades, ensure efficient resource allocation, enhance network performance and user experience.
Efficient Troubleshooting: NMS tools provide detailed insights into network issues, making troubleshooting faster and more effective. Administrators can analyze historical data, track performance trends, and correlate events to identify the root cause of problems. This accelerates the resolution process and minimizes network downtime.
Enhanced Security: NMS systems play a crucial role in network security management. They monitor and detect security breaches, unauthorized access attempts, and abnormal network traffic patterns. Administrators can implement robust security measures, enforce access controls, and respond promptly to security incidents, improving the overall network security posture.
Streamlined Configuration Management: NMS tools simplify the management of network device configurations. They enable administrators to centrally deploy and update configurations, enforce consistency, and ensure compliance with network standards. This reduces configuration errors, improves network stability, and simplifies administrative tasks.
Effective Resource Planning: NMS tools provide valuable insights into network usage, capacity trends, and performance statistics. Administrators can use this information for effective resource planning, such as identifying underutilized or overutilized network segments, optimizing network bandwidth, and planning for future network expansion or upgrades.
Reporting and Analysis: NMS tools offer reporting capabilities, allowing administrators to generate performance reports, trend analysis, and usage statistics. These reports aid in decision-making, capacity planning, and network optimization. They also provide valuable information for audits, compliance assessments, and performance evaluations.
Implementing an NMS offers centralized control, proactive issue detection, improved performance, efficient troubleshooting, enhanced security, streamlined configuration management, effective resource planning, and valuable reporting and analysis capabilities. These advantages contribute to a stable, secure, and optimized network infrastructure, increasing operational efficiency and better user experiences.
The performance of network components can be quickly affected by instability. Diagnosing network issues is physically possible with an NMS, which hampers troubleshooting.
Organizations may encounter disruptions in delivering products, making meeting the service-level agreements (SLAs) easier with an effective NMS solution.
Incorrect network configuration and insufficient network security can produce security risks, putting networks at risk of digital fraud.
Without automated monitoring provided by an NMS, administrators would have to check individual network devices for faults or errors manually. This process is time-consuming and prone to human errors. Troubleshooting network issues becomes challenging as administrators rely on fragmented information from various sources.
Businesses may experience frequent network outages and be impacted by lengthy downtime with no network management system. This can cause revenue and production levels to drop. Not all companies have enough money to pay for significant downtime costs.
How to Choose a Perfect Network Monitoring System (NMS) Wisely?
Network administrators are responsible for managing the IT network of an organization. They do this by using tools such as NMS to manage their work.
An NMS typically operates as a centralized platform hosted on a server to gather network data from devices. The server can be on-premises, in a private cloud, or the cloud. Network devices, clients, and application information can be sent over the network to the server to update their status. Network administrators can check the network status by logging through a web browser or smartphone app.
An NMS will implement network monitoring, such as packet loss, latency, bandwidth utilization, and more. It can also monitor servers or mobile devices (mobile device management) connected to corporate networks. An NMS can be programmed to monitor specific events, such as firewalls or network traffic, in real-time.
Network administrators use a network management system for a variety of purposes, some of which are as follows:
Following the best practices while implanting an NMS into your network enterprise is advised. In addition, the essential strategies that network admins can implement in an IT organization are discussed below.
Identifying Network Architecture: It is essential to study and understand the core infrastructure of your network, the requirements, and the operations performed across your network. The admins need to identify how an NMS can help gain control over the network operations. This also involves meeting standard compliances like HIPPA and PCI, which are legal requirements for health and payment organizations.
Managing Network Traffic: Once the network infrastructure is identified, the next step can be to manage the network components such as security, network devices, and network design. Again, prioritizing these helps you prevent failures and disconnectivity.
Finding a perfect NMS for your Enterprise: A powerful NMS should be able to manage the network with different parameters such as device discovery, traffic flows, risk management, etc. As a result, it helps protect the enterprise from vulnerabilities, secure the network, and grow your business.
