An evolvable network design approach with topological diversity

As environments surrounding the Internet become more changeable, a design approach that requires less equipment to scale up networks against the traffic growth arising from various environmental changes is needed. Here, we propose an evolvable network design approach where network equipment is deployed without a predetermined purpose. We enhance topological diversity in the network design by minimizing the mutual information. Evaluations show that, compared to networks built with ad-hoc design method, networks constructed by our design approach can efficiently use network equipment in various environments. Moreover, we show that, even considering the physical lengths of links, the approach of increasing topological diversity can lead to an evolvable network.
