VNE-Sim: A Virtual Network Embedding Simulator

Computer network virtualization and virtual network embedding (VNE) algorithms have gained significant attention in recent years. Performance evaluation of VNE algorithms mainly relies on discrete event simulations. However, modular and scalable VNE simulators are not available. In this paper, we describe newly developed simulator VNE-Sim that enables users to define and implement network elements possessing various resources. It also enables researchers to generate various topologies of Internet Service Provider and data center networks for the evaluation of VNE algorithms. Furthermore, VNE-Sim provides the infrastructure for implementing both single and batch request processing approaches.
