Design and Simulation Networking Operating Model for Virtual Network System (VNS)

Abstract

The goal of network virtualization is to provide systems and users with efficient, controlled, and secure sharing of the networking resources and the virtual network systems give a solution for the shortage of the traditional networks like deficiency of scalability and lack of network management. Virtual network has been looked as a helping future network technology, during multiple diversified virtual networks that can work on a participated infrastructure. So, to study and exam the management mechanism of future network, we try to improve and accomplish a model of networking operation for system virtual network. The model basically simulates a network multi-layer topology that integrates a virtual network into a virtual network system (VNS). Moreover, it also possible to simulate the operating status and network error. The validation results of model show three advantages that can effectively simulate the virtual network (VS) (a) Simulate the errors of both virtual networks and the primary network (PN), and the selection results depend on the simulated (b) simulate and test multilayer network topology model (c) working virtual network establish tests graphically and providing comparison through embedding various algorithms. finally, in order to make it easier to assess network systems beyond current simulators' competence field, a new virtual network simulation model is designed and performed.
