一种云计算的虚拟网络管理系统

云计算技术是IT产业界的一场技术革命，已经成为IT行业未来发展的方向，这种变化使得IT基础架构的运营专业化程度不断集中和提高。在云计算的使用中，云计算使用者缺乏对于网络的配置能力，这部分目前并没有开放给用户所使用。虽然云计算的虚拟网络服务已经受到了更多云计算提供商的关注，但是目前对这方面的支持还处于不完善的阶段。本文提出了一种基于云计算的虚拟网络管理系统，本系统能够以动态的方式为用户提供基于云计算的网络服务，可以根据用户需求实现虚拟网络配置，并加以优化，以便最大限度地提高虚拟网络的性能。

A Cloud-based Virtual Network Management System

Cloud computing is a technological revolution of the IT industry, and has become the future direction of development of the IT industry. This change makes the degree of specialization in operating IT infrastructure continue to concentrate and improve. In the use of cloud computing, users lack the ability to configure the network, which is not open to the user. Although virtual network services of cloud computing has got more concern of cloud computing providers than before, their support in this regard is still in the imperfect stage. This paper presents a virtual cloud-based network management system, which can provide users with a cloud-based network services in a dynamic way. Besides, virtual networks of this system can be configured according to user needs with an optimized manner, in order to maximize the performance of the virtual network.
