Traditional networks, although using stable and proven technology, do not provide enough agility for modern network environments. Software Defined Networking (SDN) is a new paradigm that corrects this shortcoming. With the help of SDN, the vertical integration of the network is separated, which means that the control logic is moved from the network devices to the outdoor unit, the so-called SDN controller. Separate control logic allows centralized network management and programmability. Due to the given specifications of this paper, the scope of research is focused on one product, VMware NSX. The NSX solution offers a network virtualization and security platform in compliance with VMware's Software-Defined Data Center umbrella model. NSX greatly expands the capabilities of the existing virtualization platform and provides several new features such as enabling microsegmentation, virtualized network functions, and automation of operational tasks in the virtualized infrastructure. NSX for vSphere offers a simplified first step into the SDN world and its benefits without the complexity of completely re-transforming the entire network infrastructure. Automatic control of elements of program-controlled networks is achieved through the Python programming language, VMware NSX-T Manager and VMware vSphera tools. The task was to get acquainted with the mentioned tools and through their Graphical User Interface (GUI) develop support for automatic provision of services within the data center, and then through Python to develop a software module for communication with the NSX-T controller from network equipment manufacturer VMware, using its RESTful API.
