The currently working traditional network architectures are not able satisfy the modern needs of users and companies. The changed demands caused to review the traditional architectures. One driver of this process is the Software-Defined Networking architecture. Currently SDN is mainly used in data centers, but due
to industry trends in networking it is a reasonable assumption that network operators and telecommunication providers will also use it in the future.
Dynamically programmable networks make the review of traditional network management and its functions inevitable. In my thesis I examine what SDN changes from the point of network management and what new options are given to the operators. I define new network management functions in SDN architecture and I implement them in a unified software environment. The unified software environment used for implementation is the POX controller which uses the OpenFlow protocol to control and manage the network. I define use-cases for each of these functions and test them in an emulated environment called Mininet.
