Question 1

What are Network Management Tools?

Accepted Answer

Network management tools enable network administrators to monitor and control the entire network (on-premises or cloud) to address service needs and business objectives. A network is created when two or more devices communicate with each other through the transfer of data. Devices come in many forms but the important network devices are clients, servers, switches, routers, firewalls, and access points. These network devices above allow common devices such as computers, phones, smart watches, IoT, and others to connect to each other. Devices can be connected physically, virtually, and wirelessly via LAN, WAN, VPN, and different types of networks.  
 All of these connections and devices are complex to manage manually. With network management software, IT managers can track what devices are connected and how they connect. Network management tools use network topology to visually lay out device connections. With this map, users can provision the network system by changing device configuration, resource allocation, and security settings to meet their IT objectives. Different network management solutions may have other network management protocols but most use simple network management protocol (SNMP).  
 Good network management software also allows IT teams to automate manual network management tasks, such as inventory assessments, device discovery and mapping, system backups, remote access, etc. The goal is to let the network management software automate these traditionally time-consuming tasks so users can focus on other things, like winning new customers and working on new business objectives. 
 
What Types of Network Management Tools Exist?
 
 Free or open-source software 
 Free network management tools perform simple internet protocols and provide basic network performance data. Since many of them require manually loading the device, free tools are perfect for small networks with fewer devices. A good rule of thumb is that if the user can map all of their devices’ topologies on a whiteboard, they should try these free tools before the paid software. Small companies or individual users are the perfect fit for this type of software.  
 Specialized network management software  
 Specialized network management software is good at doing one job—network management. This software can manage a range of functional areas: auto-discovery, inventory, performance, reliability, and security. It provides technical reports and graphs of the network system. Some more advanced tools can offer root cause analysis and machine learning to solve specific problems. These tools are excellent for organizations with other existing monitoring and management tools for their website, database, hardware, etc. 
 One-for-all software  
 Top vendors provide comprehensive network management solutions for enterprises. These tools not only do everything that a specialized network management software ca do, alsothey have additional capabilities that manage cloud infrastructure, web network traffic, and IT assets. Some even cover container management, Kubernetes control, and application monitoring. Since they are designed for enterprise-size networks, there is no limit to the scalability of the number of devices. An experienced user can automate a significant amount of manual tasks with this type of software on numerous devices. This type of software is a great fit for large organizations that have their IT infrastructure in multiple locations.

Question 2

What are the Common Features of Network Management Tools?

Accepted Answer

The following are some core features within network management tools that can help users manage their network: 
 Device discovery: Network management tools need to automatically discover new and existing devices and update this information in the device inventory. If there is no auto featuusers mustd to manually enter this information into the system.  
 Network topology: Another name for this feature is network mapping. Network management tools should map all devices in a graph to show how they are connected. This saves users time from constantly mapping their network manually on a whiteboard. They can see the entire network from network maps. 
 Configuration management: Users can set up their network configurations such as IP address and firewalls on Microsoft Windows, Linux, or website (SaaS) using API.  
 Network monitoring: Network performance should be monitored to show the status of the network such as bandwidth usage. Essential metrics must be covered in the following: bandwidth (maximum data transmission rate), throughput (data transmission rate), latency (delay between device request and delivery), packet loss (number of data packets dropped during transmissions), availability (uptime of the network), and connectivity (the types of connection between devices).  
 IT alerting: If there is a performance problem, tools that have alerting capability will notify the help desk so IT staff can start troubleshooting the network configuration. IT alerting should be integrated with the network monitoring system. For example, if remote wireless networks fail to operate, IT pros won't know there is a problem unless the network monitoring solution notifies them. 
 Root cause analysis: Just having the status of the network is not enough for modern-day network management practice. When there are hundreds of devices, users waste time trying to search which device is causing a network performance issue. The software should alert the user which device is causing the problem so the user can fix the issue fast. This feature is core to performance management.  
 Reporting dashboard: If every device is being tracked automatically, their performance information should be reported in real time in a central dashboard. It is unrealistic to expect network managers to check the performance of every device one by one. Also, different users have different technical knowledge of the network system. Therefore, reporting tools should be customizable according to the level of technical details.  
 Automation: Network management tools should automatically track network inventory, run scheduled reports, device software updates, load balance based on need, alert users of issues and where to find them, and so on. The more IT teams can automate these processes, the more time they save from doing these tasks manually. With the rise of machine learning and AIOps, these new technologies assist users in accurately determining the device at fault so users waste less time trying to find the problem.

Question 3

What are the Benefits of Network Management Tools?

Accepted Answer

Increase network performance: Since network management solutions monitor, evaluate, and report performance metrics such as traffic volume and availability. Users can use performance information to forecast resource requirements and load balance based on need. For example, if an internal network device is causing the bottleneck, then the user can upgrade their device. If the internal network infrastructure is operational but the external cloud server is limiting network performance, then users can upgrade their cloud resource capacity. Network management software provides this information so users can accurately pinpoint the performance issue and act accordingly. 
 Easily manage numerous devices: Users can manage their network and device configuration in a configuration management dashboard. This includes initializing multiple devices and maintaining settings in one workflow. The software also allows configuration backup so in the event of failure or human error, IT administrators bring the network back online without manually setting everything up again. 
 Increase network security: Security management prevents unauthorized access and cyber attack. Users can set up user authentication, data encryption, access distribution, firewall, and other security parameters to provide real-time protection.
