The functions can also be defined as a single name for a group of programming instructions written together to achieve a common task. This piece of code is triggered by controller decisions or rules, which in turn adds, modifies, or deletes configs on the multi-vendor device to ensure the rule set on the controller is adhered to. Controllers are used to take decisions in terms of creating a path for the packet to flow across the different connected devices, and switches (or network equipment) are dynamically configured from the controller based upon the path that a packet needs to take. Small sets of programs can be combined to create an application that can be installed, deployed, and configured for individual or organizational requirements.

Accounting ensures proper use of the resources, this means that everyone gets to use the services in a fair manner. Although we may have been born in different cultures, in different countries, we can use English to communicate with each other effectively, since English is the industry standard of human interaction. Any program or set of instructions may malfunction due to incorrect input or incorrect logic, which can result in unexpected behavior or unexpected results. 12. The controller, based upon its preconfigured logic, decides what action to take for that unknown packet and can get switches that it is controlling to create a separate or a specific path for that packet to flow across the network. As one of the more versatile programming languages, Python is well-known for its batteries-included philosophy, which includes a rich set of modules in its standard library; Tkinter is the library included for building desktop applications. The sample API REST call in PowerShell is as follows: As we can see in the preceding screenshot, we call the Invoke-RestMethod function in PowerShell, which is used to call the API method of the application with the default communication and interactions using JSON.
