The aim of this work is to connect dynamic identity management system developed under the project Sec6Net with a control of SDN network. The controller Pyretic is used for network control, which allows application development by using the match-action rules. Interface between the identity management system and controller Pyretic is designed and implemented in both systems. To prove the concept, selected use cases related to security, routing and accounting are created. The use cases are implemented as applications for Pyretic controller. All programs were tested in networking laboratory according to the possibilities. The main contribution of this work is to simplify and improve the management of computer networks while providing new capabilities to administrators of these networks and ultimately their users.
