Network management software


Network management software is software that is used to provision, discover, monitor and maintain computer networks.

With the expansion of the world wide web and the Internet, computer networks have become very large and complex, making them impossible to manage manually. In response, a suite of network management software was developed to help reduce the burden of managing the growing complexity of computer networks. Network management software usually collects information about network devices ( which are called Nodes ) using protocols like SNMP, , etc. This information is then presented to network administrators in an easy to understand and accessible manner to help them quickly identify and remediate problems. Problems may present itself in the form of network faults, performance bottlenecks, compliance issues etc. Some advanced network management software may rectify network problems automatically. Network management software may also help with tasks involved in provisioning new networks, such as installing and configuring new network nodes etc. They may also help with maintenance of existing networks like upgrading software on existing network devices, creating new virtual networks etc.

Provisioning: This function enables network managers to provision new network devices in an environment. Automating this step reduces cost and eliminates chances of human error.

Mapping or Discovery: This function enables the software to discover the features of a target network. Some features that are usually discovered are: the nodes in a network, the connectivity between these nodes, the vendor types and capabilities for these nodes, the performance characteristics etc.

Monitoring: This function enables the network management software to monitor the network for problems and to suggest improvements. The software may poll the devices periodically or register itself to receive alerts from network devices. One mechanism for network devices to volunteer information about itself is by sending an . Monitoring can reveal faults in the network such as failed or misconfigured nodes, performance bottlenecks, malicious actors, intrusions etc.
