Network management is the method of orchestrating network traffic and knowledge flow across the enterprise system victimization network monitoring, network security, network automation, and alternative tools hosted on-premise or on the cloud.
The first purpose of network management is to deliver a secure, reliable, and high-performing network to finish-users, as well as business users within the enterprise and end customers. Network management was perpetually an important part of the IT task list, and it’s become even more important in the wake of COVID-19. Distributed firms primarily suppose network management to stay different enterprise functions and groups connected. Network management is additionally accountable for managing knowledge flow in and out of various host environments equivalent to on-premise servers, personal clouds, and public cloud platforms.
Per the International Standards Organization (ISO), there are 5 kinds of network management to see the complete spectrum of network-related processes. These varieties are fault, configuration, accounting, performance, and security management, unremarkably said as FCAPS. allow us to explore what network management entails.
5 Types of Network Management:
-
Network fault management:
You’ll be able to have a designated network fault management team to anticipate, detect, and resolve network faults to reduce downtime. In addition to fault resolution, this operation is accountable for work fault information, maintaining records, conducting analysis, and aiding in regular audits.
There must be clear channels so the network fault management team will report back to the network administrator to keep up transparency. it’ll conjointly work closely with the end-user just in case they report faults.
-
Network configuration management:
Network configurations are a key side of performance. These configurations are expected to vary dynamically to stay up with knowledge and traffic demands during a giant enterprise. An example of a network configuration management task is an IT skilled remotely fixing the property settings to spice up performance.
Network configuration management depends heavily on automation so the team doesn’t ought to manually search configuration needs and may provision changes mechanically instead. Like network fault management, the network configuration management team should conjointly keep elaborate records of all changes, their outcomes, and issues, if any.
-
Network accounting and utilization management:
As network requirements evolve, staff can consume additional network resources and raise enterprise costs. The network accounting management team monitors utilization, finds an Anomalies, and tracks utilization trends for various departments, business functions, workplace locations, on-line products, or perhaps individual users.
In some businesses (especially digital service providers), network accounting management is directly connected to profit. For example, an ecommerce company may ought to track network utilization and benchmark against profitability throughout peak and lull periods. In giant enterprises, network accounting management could be a shared service organization that leases network resources to different branches and subsidiaries to keep up an inside profit margin.
-
Network performance management:
This can be one among the foremost central aspects of network management. Network performance management involves various tasks that facilitate boost network uptime, service availability, and co-existing information measure speeds. Here too, automation plays a serious role.
A singular dashboard is connected to varied network parts that monitor performance KPIs and raises an alert if a threshold is breached. For example, the network performance management team may need to map network response times 24/7 to avoid impacting the end-user experience. If there’s an anomaly, the network performance management team can work closely with the network fault management team to resolve the issue.
-
Network security management:
As most enterprise processes move online, network security is significant for resilience, risk management, and success. For example, 68% of enterprises as surveyed by Telia Carrier in 2020 moon-faced a distributed denial of service (DDoS) attack last year.
During a DDOS attack, multiple connected on-line devices target an enterprise web site with pretend traffic to dam legitimate traffic. Network security management involves protecting a system against these and alternative issues. An enterprise network conjointly generates an everyday stream of logs analyzed by the network security management team to search out any threat fingerprints.
Counting on your business’s size and nature, you will have selected groups or personnel taking care of all kinds of network management. A large, distributed, and transnational enterprise can usually have a team appointed to every form of activity. Specific business horizontals might have originated groups for one type of network management and cluster the remainder into a shared function.
The importance of network management has steadily matured within the previous couple of years, alongside its challenges. Fragmentation in the network management toolkit is additionally a concern, with 4-10% of enterprises victimising 4-10 tools to troubleshoot their networks.
A strong network management operation will facilitate addressing these challenges whereas keeping network prices in restraint and driving performance to support the business. To realize this, network management groups suppose a collection of distinct components.
6 Key parts of Network Management:
Network management leverages multiple connected components to execute operations. These include:
-
Termination property:
A primary purpose of your network infrastructure is connecting enterprise endpoints. this might be on-premise workstations, lobby kiosks, and room systems. It might also involve a distributed landscape that helps connect remote staff and multiple branch organizations.
The termination sort also varies counting on the business need. Network management helps make sure that the mandatory endpoint nodes are connected in the least times, and network admins have period of time visibility into the performance of every node. IT groups might also use centralized network observation tools to supervise one interface’s endpoint property for distributed locations.
-
Work systems:
Work systems are a necessary element of network management as they assist monitor network performance as per industry-standard KPIs and maintain thorough records. Work systems are hooked up to each network hardware appliances and software system components. As these hardware and software tools are used, the logging system can record all activity for future reference.
The foremost widespread logging mechanism of network management is the omnipresent Syslog possibility, a protocol that permits you to generate and maintain records for all network events in a data formatting like JSON. however this, in and of itself, isn’t of abundant use. That’s why fashionable network management connects logging systems with network analytics so that you’ll be able to visualize the data, notice trends, and receive alerts for anomalies.
-
Network automation:
Network automation reduces the manual effort concerned within the 5 different kinds of network management. It can facilitate auto-healing common problems supported by a preset protocol for network fault management. For network configuration management, automation can aid in the automatic provisioning of latest users. For network account management, it can help mechanically roll out cost-reduction measures if sure thresholds are breached.
It might automatically change application policies for network performance management to support the business. Automation lets you study totally different threat varieties and notice them with least manual intervention for network security management. Network automation is anticipated to grow from $3.4 billion in 2021 to over $8.3 billion in 2026, as per a Reportlinker report.
-
Server property:
The server connectivity element of network management takes care of the connectivity standing of non-end-user-devices. For instance, if your enterprise depends on virtual machines or a series of privately-hosted servers to power application-related processes, these ought to be unbroken online.
Network management should guarantee most time periods for server devices, a bit like endpoints. This may be a challenge as server problems may be tougher to detect, and also the downside becomes apparent solely when it unfolds across the enterprise. This can be why most network management groups use server-specific network observation tools to keep up and manage this component.
-
Switch management:
Network switches are hardware appliances that facilitate connection termination devices to the first enterprise network whereas implementing the mandatory IT protocols. firms might use multiple levels of network switches, starting from floor switches to aggregation switches and the central switchgear.
Switch management provides you visibility into traffic flowing in and out of switches therefore you’ll be able to diagnose upstream issues, guarantee consistent speeds, and anticipate bottlenecks. Today, the switch management element has become extremely sophisticated. It permits you to watch and orchestrate advanced landscapes victimization switch management software. This helps produce a visible floorplan of your enterprise atmosphere and control switches connected to your finish devices.
-
Network assurance:
The network assurance component of network management involves policy social control to manage risk, ensure internal compliance, and shut security threats. the aim of network assurance is to deliver a secure and reliable expertise to any or all users. That’s why this element needs collaboration between all 5 kinds of network management to work smoothly. Also, network assurance utilizes analytics as a key component to watch dynamic risk levels and alert the mandatory stakeholders before a severe issue will arise.
Ultimately, these parts are a part of a three-pronged network management design that has a managing entity, a managed device, and a management protocol. The managing entity includes the personalities and technologies accountable for governing the landscape – e.g., an IT administrator or an automation script. The managed device is on the receiving end of network connectivity, such as endpoints, switches, and servers. Management protocols sit down with the intercessor rules and policies that govern the connection between the managing entity and also the managed device.
