What is Network Management And Is it Important ?
Network management is the process of operating and managing a data network using a network management system. The latest network management systems use software and hardware to continuously collect and analyze data and drive configuration changes to improve performance, reliability, and security.
The network management devices such as switches, routers, access points, and wireless controllers. Servers can be located in private data centers or the cloud. Interlinked devices, clients, and applications on the network can send data to the server with their status updates. Administrators can see networking operations by logging on to the server, usually via a web browser or smartphone app.
Is Network Management Important?
The hardware such as routers and software such as applications allow information exchange between the devices connected through networking. However, some of these components can become damaged at any time and due to various factors. Resulting in blocked Internet access and the inability to share valuable resources across network devices such as fax machines.
This could lead to more extended downtime and loss of production and sales for the company. Hence, it is essential to incorporate network management into your business combination to ensure that your computer network continues to perform correctly. Network management allows administrators to monitor and manage your network. All of its intricate parts using a variety of tools to prevent damage.
Fundamental Elements Of Network Management
Modern data networks have become essential assets for many industries. Most of the primary data networks are used to connect users and provide them with access to various resources, such as B. Internet and other computers connected to the network. A network consists of four main elements: hardware, software, protocols, and communication media. All data networks are composed of these elements and cannot function without them.
An essential element of network management is error management. Error management refers to the maintenance of network infrastructure and protection against threats. It is a process for identifying, documenting, and fixing errors affecting your network system for effective network management. It would help if you had logs to identify potential problems and alert the appropriate IT staff.
In many corporate networks, individual departments, or cost centers. Even separate project accounts are charged for the use of network services. This is an internal accounting procedure, not an actual transfer. But essential for the users involved. Even if the internal charging is not used, the network manager must track network resources. Usage by users or user classes for some reason. The network manager must determine the types of accounting information to be recorded at different nodes. The desired interval between the sequential transmission of recorded data to the higher-level.
Configuration management deals with network initialization and fine-tuning of part or all of the network. It is also involved with maintaining, adding, and updating connections between components and the state of the elements themselves during network operation.
Starting and shutting down the network is a specific responsibility of configuration management. Often specific components should perform these operations unattended (such as starting or turning off a network interface unit). The network manager must first identify the features that make up the network and determine the desired connectivity from these components. Those who regularly configure networks with the same or similar resource attributes need the possibility to define. Modify standard features and load these groups of predefined features into defined network components.
The network manager must change the connectivity of network components if the user needs to make changes. Network reconfiguration is often desirable in response to a performance assessment or to assist with network updates, troubleshooting, or security reviews. Therefore, when the configuration changes, a notification sent to users. Before reconfiguring, users often want to ask about the future status of resources and their attributes. Network managers usually only want authorized users (operators) to manage and control network operations (for example, distribution and software updates).
Hardware & Software
The backbone of a network is the hardware that runs it. Network hardware includes network cards, routers or network switches, Ethernet modems, and repeaters. Without this hardware, the computer cannot access the network. Network cards allow computers to directly access network media and connect to other devices, including routers, switches, modems, and repeaters. Using a router or switch, a single modem network connection can be shared by multiple computers. The repeater updates the network signal between Ethernet cable segments so that Category 5 cables can reach a maximum length of 300 feet without signal loss.
For hardware devices to interact with the network, command software is compulsory. The main form of network software is protocol – software that instructs network devices to connect with the network and interact with each other. Other examples of network software include connection monitoring software, network clients, and other tools designed to make it easy for your computer to connect to the network.
Administrators also collect and analyze performance data to set performance thresholds to prevent system functionality from being exceeded. Performance management is based on measuring and collecting required data. It is essential to understand the operation of the system and compare it with technical objectives. In Appendix A, we consider several performance criteria for IMS networks.
Security management covers areas of the network domain and access security model. It also provides NE users an access control mechanism provided as authorization to perform certain tasks at specific times. Subscription management is concerned with giving profiles and customer service in HSS and the appropriate USIM configuration. Software management includes provisioning, installing, and activating the IMS NE software. And its also provides for the provision of software for initial installations and live network upgrades. Roaming Management includes contractual and usage agreements with other service providers to match customers’ roaming from their home network to the networks they visit. Fraud Management provides functions to detect and prevent fraud, particularly for roaming and mobility services.
The main component of network management
System network management services are vital for any business association because your business operation depends on the system’s smooth running. The fact that failure of any network device will result in many downtimes that will affect your business. There are many different parameters such as network management applications, processes, networks, and various procedures to be considered in an inspection plan.
The software used to perform network management tasks resides on the host computer and communication processor (e.g., front-end processor, terminal cluster controller, bridge, router). The network management system treats the entire network as a single architecture, with addresses and designations assigned to each point and specific attributes of each element and link known to the system. Active network elements provide regular feedback on the status of the network management center.
Change service is significant for system accessibility. Many people make lots of unapproved repairs without paying attention, which can cause problems if progress doesn’t work correctly. Advances in organizing the generation should be part of the system operation and the relevant people of IT support personnel.
