Network Management System (NMS) are an application or set of applications which allows network engineers to manage the independent components of the network within a broader network management framework. A network device (wireless as well as wired) is identified, configured, monitored, updated and troubleshooting in a company's network. A system control application shows the performance data from each network component, which can be changed as needed by network engineers. It includes hardware and software, but usually an NMS is used to manage a network with a software.
If management system is fragmented, network management in large provider-grade environments can be a difficult business. Ops Managers and engineers need to handle consistent IT services including monitoring, optimization, security and expansion of customer-free networking environments effectively and efficiently. But networks are growing and also increasingly difficult to manage. There is a need for integrated network management systems that simplify the tasks of running a large-scale operation without adding overhead.
In order to ensure that systems provide services optimally around the clock, service providers need end-to-end visibility in multi-provider networks. The integrated system management solutions go as far as systems require. Numerous NMS offers are excellent in one aspect of network management but are limited in other aspects. It's hard to find a management solution that does it all, leading to IT departments investing in widely disparate and over-complex systems that sooner or later become white elephants.
Due to limited technical know-how and staff, small companies have different network management needs and expectations. They want low cost, easy to install and use tools and rich features. The management requirements are generally small with small companies and home networks. Some instances may, however, require a certain amount of setup and notification.
Network management's ultimate objective is to reduce risk, eliminate downtimes, reduce variability and actively support business expansion. The number of businesses carried out that do not rely on networks that are available is small and declining. An important asset that protects the company against slowdowns and disastrous failures that would have a major impact in business is considered as a good network management system.

Performance management aims to assess and report the behavior and effectiveness of the network objects managed. A network monitoring system can measure and display the network condition, for example collecting traffic volume statistical information, network availability, response times and performance.
Fault management involves detecting, isolating and revising abnormal operations which can cause the OSI network to fail. The main objective of fault management is to always make the Network available and to fix it as quickly as possible when a malfunction occurs. Faults must be separate from mistakes. In general, an error is only one event, while a fault requires management attention and is an abnormal condition. For example, the physical line cut is a fault, whereas a single bit error on a line is an error.
Security Management prevents unauthorized access and security attacks by networks and systems. Authentication, encryption and authorization are included in security management mechanisms. Security management also involves generating, distributing and storing encryption keys and other security information. The management of security may include security systems including firewalls and intrusion detection systems that provide real-time event logs and monitoring.
Medical providers continue to struggle to reduce patient costs, to offer higher quality services, to make patient connectivity more accessible, etc. The medical sector is now looking closely at IT solutions to address these problems. A network of healthcare providers involves all the doctors, physicians, hospitals, clinics, pharmacies etc. that have been contracted to extend medical attention and care to their members within a specific plan. In this plan, healthcare providers are referred to as network providers. Healthcare and medical service providers who are not a part of any specific plan are referred to as “out of network providers”.
Industrial production steps across the walls of the individual companies, so that new management approaches are required to coordinate the work of the various manufacturing companies. To balance out the production and maximize the profit of a group of SMEs based on the holonic paradigm, a new manufacturing networks model is proposed.
The network is conceptualized as a set of equal rights operational nodes, coordinated by a central unit that communicates with customers, distributes tasks to nodes on the basis of prefixed criteria and up-to-date node state and reliability information, and informs each node about their position in the network with respect to the manufacturing process.
There is an increased need for a secure and agile infrastructure to work effectively in a sophisticated business environment to boost demand over the prediction period for these solutions and services. NMS solution distributors are also expected to experience significant prospects over the forecast period, since small & medium-sized enterprises continue to implement wireless and wired LAN infrastructure across cloud-based solutions, reduce global infrastructure costs and facilitate data access. In addition, they are expected to be able to achieve greater efficiency. The bottom line is that the worldwide market for Network Management Systems is being estimated to grow at a CAGR of 10.2% in the years to come.
