Abstract This dissertation was written as a part of the MSc in ICT Systems at the International Hellenic University. SDN is a network approach that separates the control plane from the underlying systems that forward traffic to the sele cted destination. In SDN networks, management functions have to be effective to ensure performance and availability. In this master thesis, ma n- agement functions of SDN networks are studied through the perspective of the FCAPS ISO framework. Existing studie s, use cases and ONF SDN features are used as sources of information that help in identifying and evaluating management functions. The cat e- gorization of the evaluated functions according to the FCAPS model, allows us to argue that, through the perspective of FCAPS model, the Network Management of OpenFlow based SDN networks can be considered effective as soon as it is supported with trad i- tional network management mechanisms and third party OpenFlow - companion sol u- tions. Issues that still exist in limited num ber of management functions mainly concern carrier - grade networks. Further investigation, programmability effort and continuous development of OpenFlow is required. I would like to thank my supervisor, Professor Andreas Pitsillides for giving me the o p- port unity to work with an interesting and emerging technology. His guidance and support played a very significant role to the development and completion of this thesis. I would also like to thank my family for being supportive and patient throughout the thesis work
