One methodological approach to the development of dynamic adaptation structures in network simulators

This paper examines the possibility of MPLS-based network to perform adaptive routing based on traffic engineering and the possibilities of using the network simulator for testing network architectures that are capable of adaptive routing. The analysis of existing architectures and mechanisms for traffic engineering showed that the considered architecture shown stationarity and can not follow the dynamics of traffic in next generation networks. To improve the efficiency of utilization of allocated bandwidth, a solution is proposed in the area of dynamic adaptation structures. The analysis of scientific studies in this field, and documentation for the available network simulators found that there is currently no support for dynamic adaptation structures in the simulator. In order to achieve the development of adaptation structures independent of the type of adaptation layer and network simulator, a detailed methodology is proposed for the development of dynamic adaptation structures in network simulators. According to the proposed methodology, a successful implementation of an example adaptation layer is performed in the network simulator OPNET Modeler 14.5, which is confirmed by simulation results.
