    Notes: Abstract This paper presents a scenario-orientedoptimization model and solution algorithm to solve thejoint routing/capacity assignment problem for computernetworks. The advantage of this model is that failures are directly dealt with at the design stage.The model helps to find a suitable trade-off betweencapacity assignment and performance in the event offailures. As accounting for major failures can be very time consuming, we introduce parallelism as atool to solve this type of problem. Two parallelversions of the algorithm were implemented. Bothparallel versions were found to be extremely efficientin reducing computational time, the one presentingtwo levels of parallelization was found more suitablefor larger networks.

    Centralized and decentralized stochastic routing models in telecommunication networks (1993)

    Notes: Abstract With the advent of non-hierarchical routing in circuit-switched telecommunication networks, on-line routing policies have been developed with the objective of optimizing some measure of gain or performance. These policies are decentralized. However, traditional planning models are centralized models. We present a decentralized routing model to be used in network planning. We compare it theoretically and empirically with a centralized multicommodity flow model previously presented. The two models are solved by the same type of algorithm, a convex simplex implementation, adapted differently according to the model. Comparative results between planning models reproducing the two policies are discussed.

    Notes: Abstract In this paper we introduce a new methodology to adjust link capacities in circuit switched networks taking into account the costing policy and reliability considerations. This methodology, which is an extension of previous work on reliability evaluation using routing models, is based on a cyclic decomposition algorithm which alternates between a routing subproblem and a link capacity adjustment subproblem. The proposed procedure, which is shown to converge to a global optimum for the dimensioning/routing problem, has been tested on a 14 undirected arc problem for various levels of link failure probability. The numerical results are extremely satisfactory and they demonstrate the usefulness of the proposed method for proper network dimensioning.
