Areas of Network Management
Networks are composed of devices that are connected. Earlier in business, the internal network is maintained and allowed every person inside the company to access the systems. But now different networks are connected via the Internet and there is a great need of managing them. Here comes the word “Network Management” which manages and monitors every system’s hardware and software in the network. For this Network Management, peoples are hired as network Administrators and network Manager who checks for the issues in the network, update the required ones, set up a protocol to manage new networks entering the existing system, and also maintains the complete lifecycle of the network.
Network Management
Over the decade, Network Management has evolved a lot to help IT services in a more advanced way. It helps the IT teams to monitor the Network performance. The Organization is not only the workplace for employees now and many people are moving remotely, so the need for cloud environment is a must. Advanced technologies like Machine Learning, Artificial Intelligence, Data Analytics, and automation are needs to be maintained optimistically.
Implementation of Network Management
Network Management is deployed in devices like switches, routers, and firewalls to get the data from them and store it in the cloud.
Using the data collected, the devices in the network are managed to monitor their performance and security issues and troubleshoot quickly when they are any network issues.
Initially, the network management was meant to monitor only Local Area Networks.
Due to the growing complexity of networks, they are implemented in security, IoT, and Data storage.
Areas of Network Management
There are five main components of network management are −
Fault Management
Network Fault Management involves detecting an issue, isolating or separating it from the network, notifying the network Administrators about the issue, and finally finding a solution to it. This process takes less time to resolve the problem and thus reducing the system time and failures.
Detection − The first step of fault monitoring is detecting the issue. There are two ways of monitoring namely active and passive. The Active one is performed through different protocols like TCP, UDP, and ICMP ping for checking the current status of the system. Passive monitoring detects the fault only after the fault occurred.
Separation − The detected fault is separated from the network and it will find the root cause of the problem.
Notification − Once the Fault is isolated, it is informed to the network team. So the team will be alert and avoid more faults will not happen.
Resolve − The fault is documented and we can either fix the problem or replace the source.
Configuration Management
The Configuration of networks plays a major role in reducing the downtime of the network. The process in the network is monitored and the changes in the command line interface are noted down manually before, which fetched many manual errors. But now using network configuration helps to compare the current configuration list with the previous one and the changes are monitored. Some of the features are −
Finding a perfect network diagram − The Network diagram should be accurate and perfectly designed which maps network elements to the hardware and software of the system.
Configuration backup − It involves getting the configuration settings and storing them for later use.
Monitoring the changes − It monitors for any changes in the devices.
Policy compliance − It helps the organization with the policies and securities.
Performance Management
It involves the process of managing the device to ensure optimal performance. It regularly monitors the device’s quality and performance. The Network Performance Management software can be chosen according to the need of the organization. Some of the strategies followed are −
Data − Gathering high-quality data and also monitoring the network traffic, packet loss, and bandwidth usage.
Analyze − Analyzing the data gives an increased performance by checking areas that need to be more focused.
Security issue − If a network is prone to security threats like malware then it will automatically reduce the network performance.
Security Management
The Policies have to be up-to-date to protect the network from attackers. This security management helps to maintain security in policy and the virtual and physical firewalls. So, using the firewall and workflow tools the security can be improved, and the high level of visibility to the network.
Accounting Management
Accounting management means administration management. It is primarily used to measure network performance metrics and all the network consumption is recorded. This Accounting management helps to manage the profit of an organization and keeps all the related documents.
Conclusion
Network Management has become crucial nowadays for both personal and business purposes. As per the ISO, network management is used for managing five different areas. From setting up a network, constructing the parameters, managing the errors, calculating the performance of the networks, and also maintaining a secured system.
