    Computer networks monitoring and management methods
    (Національний авіаційний університет, 2018-10-31) Savchenko, Alina; Vasylenko, Valeryi; Kolisnyk, Olena; Holiavkina, Tatyana
    The distributed architecture of monitoring and management systems based on the SNMP protocol, the MIB databases and the centralized architecture based on the SDN network concept and the Openflow protocol are considered. The advantage of centralized monitoring and control is the ability to form a holistic view of the network status, respectively, to calculate the global optimum control and load balancing. The disadvantage is the low resiliency of the network, the complexity of managing a large system. Monitoring and management of such a complex system is possible with the help of decentralization, the creation of a hierarchical structure, the use of heuristic or metaheuristic methods for optimizing large systems. A method with sliding a posteriori optimization, which allows to achieve the optimal number of hierarchy levels and the optimal number of devices on the same level, is proposed
