Network management systems (NMS) refer to software suites and applications that help organizations monitor, control and plan their IT infrastructure and communications networks. A key responsibility of any NMS is to provide a centralized view into all the devices that make up a network including routers, switches, firewalls and other critical assets. This involves collecting performance metrics and operational data from each device and presenting it in a clear, visual interface for easy comprehension.
Monitoring Network Health and Performance
One of the core functions of an NMS is to monitor the health and performance of the entire network on an ongoing basis. It keeps tabs on key indicators like bandwidth utilization, device uptime, traffic volumes, packet loss, latency and more. If any critical thresholds are breached or anomalies detected, the NMS can automatically trigger alerts to network administrators. This helps identify problems early before they majorly impact end users. Advanced NMS tools even correlate data from multiple sources to pinpoint the exact root cause of issues.
Configuration Management
Managing configurations securely across hundreds or thousands of distributed devices is an intimidating task without the right automation tools. Network management systems simplify this through centralized configuration repositories that store baseline configurations. Any future changes can be tested first before being deployed globally through the NMS. It also enables comparing running configurations against known-good configurations to spot any deviations introduced unintentionally or by rogue actors.
Asset Tracking and Inventory Management
With so many hardware and software assets involved, keeping tabs on all inventory can turn into a nightmare without proper tracking mechanisms. NMS platforms maintain a real-time inventory of all devices including their specifications, locations, warranty/support timelines and more. This aids in tasks like hardware refreshes, capacity planning and budgeting for replacements. Some solutions even integrate with procurement and billing systems to streamline the entire lifecycle management of network resources.
Network Documentation
Documenting complex networks is tedious and error-prone if done manually. Network management systems automate this by taking regular snapshots of the logical and physical topology maps. These topology diagrams could be network-specific or even multi-domain for cloud, IoT etc. Additionally, visual tracing tools make it easy to drill down and view end-to-end connectivity paths. Comprehensive documentation serves as a single source of truth during audits, troubleshooting or transition periods involving new teams.
Change and Release Management
Network changes if not managed carefully can unintentionally bring down critical services or open security holes. NMS offerings provide workflow-based change management modules where any updates go through defined approval processes. They also help automate rollbacks in case of failures during deployment. Along with tracking individual changes, release management capabilities consolidate multiple approved changes as formal, tested releases.
Predictive Analytics and Reporting
More sophisticated NMS tools deploy techniques like machine learning on historical data to gain insights and predict future behaviors. For instance, traffic patterns can predict capacity requirements, device usage can predict failures and anomalies could predict security threats. Configuration drift over time is another area where predictive insights help stability. Besides graphs and dashboards, customizable reports deliver key performance metrics and analytics to stakeholders on-demand or through scheduled deliveries.
Network Access Control
With perimeter networks blurring due to mobility and cloud adoption, network access control becomes more important than ever. Advanced NMS can integrate with directories as the central source of user/device identities. Using this identity data, they can enforce granular, policy-based access to network segments, remote access VPNs, WiFi etc. Detailed logs also help audit past access transactions for compliance.
Vendor and Technology Agnostic
Since enterprises today deploy an increasingly diverse array of gear from multiple vendors, a key NMS selection criteria is cross-vendor compatibility. Best-in-class solutions support discovering, monitoring and managing devices irrespective of manufacturer or underlying transport technologies like Ethernet, WiFi, SD-WAN etc. This simplifies managing heterogeneous infrastructure through a single pane of glass.
Benefits of Network Management Systems
To summarize, network management systems deliver clear benefits across people, processes and technologies when implemented effectively:
- Improved visibility into network health, performance and potential issues.
- Automated configuration backups, deployments and auditing reduce errors.
- Centralized change management streamlines updates and rollbacks.
- Comprehensive documentation aids troubleshooting, audits and onboarding.
- Predictive analytics help optimize investments and catch anomalies proactively.
- Standardized reporting satisfies compliance requirements and stakeholder needs.
- Vendor-agnostic capabilities unite visibility of hybrid, multi-vendor networks.
- Lower operational costs through reduced mean-time-to-repair, less firefighting and optimized staff utilization.
- Enhanced network/service availability, reliability and user experience through proactive issue identification.
- Stronger security posture monitoring through integrated solutions and change control.
