Evaluation of SDN network scalability with different management level structure

Evaluation of network scalability, based on the concept of SDN, is an important task in the design of a new or expansion of existing network architecture. Therefore, different structures of management level were considered and the mathematical model of SDN network was built for these structures in the work. Structure components models of SDN network were considered: data level model, flow initiate model, controller model. Different structures of management level were also considered: centralized, local decentralized, global decentralized, hierarchical and alternative approach of management level building. The results of work can be used for further research of the basic principles of SDN network and fragments building of real networks using software Mininet.
