A novel cognitive management scheme for the virtual network resources

As a long term solution to the gradual Internet ossification problem, virtual networks can guarantee on-demand requirements of diverse end user on a global level. Clearly it is a major challenge to achieve the automation and optimization of network management like virtual resources or QoS to ensure the personalized user satisfaction. In this article, we propose a novel cognitive management architecture to meet the future needs under a heterogeneous network environment. The architecture introduces a cognitive management cycle to the virtual network resources to ensure flexibility. We also focus on the efficient virtual network resource allocation and scheduling algorithms. Based on the complex network centrality analysis, we solve the virtual network resources allocation problem with consideration of the topology structure and statistical analysis. Finally we evaluate the efficiency and effectiveness of our algorithm on common benchmarks including the acceptance, revenue and cost.
