NetzwerkmanagementTools

NetzwerkManage is a term used in information technology to describe the set of processes, tools, and protocols used to administer and optimize computer networks. It covers activities designed to ensure reliable connectivity, predictable performance, and robust security across network devices such as routers, switches, firewalls, access points, and servers. The concept encompasses both traditional on-premises networks and modern, cloud-enabled architectures.

Core functions typically include fault management (detecting and resolving problems), configuration management (maintaining device settings), performance management (monitoring utilization and quality of service), and security management (controls and policies). Management planes involve management stations, software consoles, and agents installed on devices, with increasing use of programmable interfaces and APIs to automate tasks. Standards and protocols commonly employed include SNMP for monitoring and basic configuration, NETCONF and RESTCONF for structured device configuration, and streaming telemetry for near real-time data. Logging and event data are often centralized via syslog, while traffic analysis may use NetFlow or IPFIX.

In practice, Netz­werkManage is implemented through network management systems (NMS) and, in modern networks, through software-defined networking (SDN) controllers and cloud-native management platforms. Applications span enterprise IT networks, data centers, service provider backbones, and industrial networks. Trends in the field emphasize automation, policy-based management, and closed-loop remediation to reduce manual intervention. Security considerations focus on protecting management channels, enforcing least-privilege access, and ensuring proper segmentation of management data from user traffic. Challenges include scale, device heterogeneity, interoperability between vendors, and maintaining up-to-date skills.
