Popis: In this paper we consider designing a high-speed virtual private network using a combination of heterogeneous telecommunication services. In particular, we consider mixing SMDS access lines and point-to-point digital leased lines to construct a virtual private network at minimum cost. We develop a nonlinear combinatorial optimization model and a simulated annealing algorithm to find a high-performance, low-cost network design. We compute lower bounds on cost savings from using mixed services as opposed to pure SMDS based on actual tariffs and realistic traffic.
