网络虚拟化被认为是互联网逐渐僵化的一个重要的潜在解决方案。在网络虚拟化环境中，一组虚拟网络共享一个物理网络的资源，但每个虚拟网络之间是相互隔离的。好处包括增加灵活性、多样性、安全性和可管理性。资源发现和分配是创建新的虚拟网络的基本步骤。本文综述了网络虚拟化中资源发现与分配的研究现状。我们还描述了这一领域的挑战并提出了未来的研究方向。
Network virtualization is considered an important potential solution to the gradual ossification of the Internet. In a network virtualization environment, a set of virtual networks share the resources of a common physical network although each virtual network is isolated from others. Benefits include increased flexibility, diversity, security and manageability. Resource discovery and allocation are fundamental steps in the process of creating new virtual networks. This paper surveys previous work on, and the present status of, resource discovery and allocation in network virtualization. We also describe challenges and suggest future directions for this area of research.
