In network automation, the tasks and functions of a network are automated using a combination of software and hardware-based solutions. Enterprises, service providers, large organizations, and enterprises can set up network automation to manage network processes that are repetitive and to improve the availability of the network service. To show you why you need to implement network automation, we are going to look at five ways.
To avoid human error
The primary reason for network automation is to avoid human error because it accounts for at least 40% to 80% of network failures. It is said that automation reduces errors. Updating the various configurations of different switches and routers is not easily done manually. Automation reduces these errors because upgrading all the configurations of all the switches and routers should be done automatically.
In network analysis, data about the network is collected, and an analysis is done to identify any issue or potential problems on the network. For the simple analysis, you will identify the interfaces that are using a lot of resources.
For complex analysis, data will be analyzed from different sources like determining that there a VRRP group has one router instead of a peer router. But for the most complex analysis, several data sources like operational data and configuration files to identify network problems.
When it comes to other network analysis, data sources like SNMP traps and syslogs are used. When you automate the network analysis, you will be able to identify network issue much faster and resolving the problem will also take a short time.
The drawing of the network topology is valuable when troubleshooting. It is tough to keep the network drawings updated. But for the NMS, it collects the connectivity information and displays them in a drawing tool.
The use of topology information cuts across network planning and the prevention of outages. This information allows you to get answers about the ratios of uplink oversubscription, verification of redundant connections, and the identification of strange topologies that can quickly appear in most networks.
Scaling of processes
If you want to have a network that is running smoothly, several processes need to be done to manage the network. Since these processes take time to implement on a manual basis, they are hard to perform, but when you have network automation, you can perform these processes on a regular basis, to reduce the risk of having a network downtime.
Once the results are produced, exceptions and alerts are sent to the network administrator. These processes include:
Saving configurations: all configurations need to be saved to a backup server and in a non-volatile storage device.
- Compliance: check if the security settings of your switches and routers adhere to our network policies.
- Improve network resilience: you network engineer has to know how to configure HSRP. Once that is done you need to verify that it is working properly.
- Consistent deployment: is the same OS being used by all the devices? When you mix several OS versions, you can easily encounter a bug in your network that you did not expect.
From these steps, you should be able to get your network up and running smoothly. And it will take you less time to run your company.
