Adaptability of Virtual Network Topology Control Based on Attractor Selection against Multiple Node Failures

Abstract

We propose a virtual network topology (VNT) control method that is adaptive to environmental changes in a network. It is based on attractor selection, which models the biological systems that behave adaptively against changes in their surrounding environments. The simulation results indicate that our VNT control method adaptively responds to changes in network environments caused by node failure and constructs operational VNTs in more than 95% of simulation trials when 20% of nodes in the physical network fail simultaneously.
