VPN Designer NC software

The article discusses a software for virtual private network analysis and planning that allows to determine the optimal topology of routes for a virtual private network, taking into account the routes and characteristics of cross-flows of other networks, such as burstiness and the traffic flow rate. The problems arising at the planning stage of VPN networks during their joint implementation in the network of the telecoms operator are considered. Differences between deterministic and stochastic network calculus are shown. The models underlying algorithms for determining the deterministic and probabilistic boundaries for virtual private network flows are studied. The basic functionality of the software is considered. The results of a study of the influence of cross-flow routes of other networks on the VPN delay bound obtained using different models are presented.
