In this thesis we presented virtualization in computer networks. Firstly, we exhibited the main types of virtualization used in computer networks and described some of their main advantages. The incorporation of virtualization in computer networks was supported by practical examples. In each case we analyzed the state before virtualization, the process of virtualization of individual network components and the state after virtualization, where we mainly observed the gains that virtualization has brought. With the thesis we portrayed the methods used in the physical-to-virtual migration of network components, as well as methods for new implementations of virtual instances in the network. We have also displayed the advantages of virtualization, compared to computer networks where virtualization is not used.
