【摘要】：网络虚拟化是未来网络的关键技术之一,有助于克服当前网络的"僵化"问题,能够在无须对当前网络架构进行巨大改变的基础上配置新的网络协议和服务,实现多个虚拟网络共存于一个物理网络上,由此产生了新的问题,如何将有限的物理资源合理分配给不同的虚拟网络,即虚拟网络映射问题。根据网络环境,分为有线网络和无线网络下的虚拟网络映射。其中,有线网络下的映射是研究虚拟网络映射问题的基础和重点,已有大量算法提出。为了给该问题的研究提供一个全面的视野,从问题定义、存在挑战、映射目标方面对有线网络中虚拟网络映射算法进行综述,根据算法的不同特点进行分类,重点介绍几种典型的算法并进行比较总结,最后指出未来的研究趋势。
[Abstract]:Network virtualization is one of the key technologies of the future network, which can overcome the "rigidity" of the current network, and can configure new network protocols and services without the need to make great changes to the current network architecture. The realization of multiple virtual networks coexisting on one physical network leads to a new problem. How to reasonably allocate the limited physical resources to different virtual networks is called virtual network mapping problem. According to the network environment, it is divided into wired network and wireless network virtual network mapping. Among them, mapping in wired networks is the basis and focus of virtual network mapping problems, and a large number of algorithms have been proposed. In order to provide a comprehensive view for the study of the problem, this paper summarizes the virtual network mapping algorithms in wired networks from the aspects of problem definition, challenges and mapping objectives, and classifies them according to the different characteristics of the algorithms. Several typical algorithms are introduced and compared with each other. Finally, the trend of future research is pointed out.
