Tiivistelmä
The purpose of this thesis was to evaluate a new network management solution offered by the YANG data modelling language and the NETCONF network management protocol. The evaluation set out to answer the question if this network management solution is an efficient, secure and reliable way to dynamically manage networks. In addition, the new emerging network paradigms Software Defined Networking (SDN) and Network Function Virtualization (NFV) were examined to understand how this new network management solution relates to them.
The fundamental network management capabilities of network management solutions were examined for the purposes of the evaluation. The used source material included specifications of many network management protocols and research papers related to the field of network management. Moreover, a new YANG model was modelled and a prototype NETCONF server was implemented. The model was done to get a more in depth view of the data modelling process. Whilst, the server was examined to get an understanding of the server's internals and implementation details. The gathered information was used to evaluate the suitability of this new network management solution for the use of SDN and NFV. Furthermore, this new network management solution was analysed based on its strengths, weaknesses, opportunities and threats.
In the evaluation it was observed that this new network management solution is substantially better for network configuration compared to the other solutions. However, it was observed that for network monitoring this new network management solution does not offer the same level of efficiency as some of the other solutions. In addition, this new network management solution was found to offer a more sophisticated and versatile information security and user management controls than the other solutions. The analysis showed that the strengths of this new network management solution were open interface, extendibility, security, reliability and performance, whilst the weaknesses of it were resource consumption and low utilization.
The conclusion of this evaluation was that this new network management solution does offer an efficient, secure and reliable way to dynamically manage networks. However, many of the other network management solutions are still seen as useful solutions in their own limited areas.
