Abstract Telecommunication network topologies are dynamically changing nowadays. The core telecommunication networks are basically based on fiber optics infrastructure. In such networks WDM technology is used to transmit multiple flows of traffic over a single fiber. Virtual network topology (VNT) is used to route IP traffic over WDM networks. VNT control system must be adaptive to traffic changes and dynamically reconfigure VNT. This can be achieved by using attractor selection, which models biological system behaviour. Biological systems are extremely adaptive to unknown changes in environmental conditions. This adaptability could be used as a model for VNT control system. The attractor selection in this VNT control method is based on a system of stochastic differential equations, which use load on links, retrieved by SNMP, and stochastic fluctuations – Gaussian noise – as input parameters to dynamically reconfigure VNT. The object of the paper - how adaptability of VNT, controlled by attractor selection, depends on regulatory matrix. The regulatory matrix is the most important parameter in attractor selection method, since it shows the relationships between node pairs. The variety of network topologies has been simulated with different activation and inhibition probabilities as well as with different regulation function threshold.
