Abstract:
This paper presents an efficient strategy for the optimal network redesign with a biconnectivity-oriented topology (both edge and vertex biconnected). It helps re-designing existing networks or generating new networks considering practically relevant constraints (such as leased lines with long running contracts to remain, maximum number of ports per device) typically found in these phases. The proposed strategy is composed of Reduction, Augmentation, and Fine-Tuning Reduction. Empirical tests using several IP network topologies showed the robustness and applicability of the method. Its application to other optical backbone (or access) network redesign problems is possible.
