Ushakov U.A., Konnov A.L., Polezhaev P.N., Shukhman A.E. SIMULATION MODEL OF VPN NETWORK WITH DYNAMIC AUTOCONFIGURATION Nowadays virtual private networks (VPN) are widely used to connect distributed network segments. We have developed the concept of self-organizing virtual private network based on cloud technologies. Deploying VPN can be greatly simplified by using the automatic configuration of network devices based on various algorithms for determining the network topology as well as routing methods. VPN control and routing algorithms may be studied on the basis of simulation. The article presents the simulation model of a self-organizing VPN. Testing has revealed the dependence between increasing the network load and node communication failures. The VPN simulation model can be used to conduct experiments on any topologies, as well as for development of the network segment simulator.Key words: virtual private networks, simulation model, software-configurable network, network as a service.
