Implementation of Software-Defined Networks Using Open-Source Environment

The paper gives an overview and analysis of software-defined technologies in the context of the actual problems of conventional computer networks. The virtualization process lies at the basis of software-defined network architecture. The basic concepts of software-defined networks are elaborated, as well as their implementation and configuration in cloud environment using OpenStack open-source software with Microsoft Hyper-V hypervisor. The practical part of this research showed that the implementation of a software-defined network into an existing standard network is relatively simple to realize, remaining all the time in open-source framework. All existing network functionalities were held, and it is also possible to provide additional network operations such as traffic monitoring in a completely open-source environment.
