Investigation and simulation of system for data flow processing in multiservice nodes using virtualization mechanisms

In this paper we propose a mathematical model of the functioning of network device with virtual routers. This model allows to decrease the mutual influence of the parametric effects of different types of traffic in the network node, as well as to estimate the quality of service by decomposition of a structure of network node and mathematical modeling based on queueing theory. To verify the proposed solutions we developed a structural and functional model of network device with dynamic virtualization of computing resources. This model allows to describe the process of router virtualization with optimization of specified level of QoS parameters for specific types of services.
