软件定义数据中心网络研究

[摘要] 提出了一种基于软件定义网络的数据中心网络方案，并对其结构和部署进行了详细介绍。通过使用软件定义网络技术，该方案解决了传统数据中心中网络利用效率低下、管控方式复杂、建设运维成本较高等问题。该方案具有结构简单、易于部署的优点。在负载均衡、域内虚拟机迁移等典型应用中，我们对该方案进行了验证，结果表明该方案具有良好的实用性。该方案为数据中心网络架构设计提供了一种重要思路。

[Abstract] This paper proposes a data center network deployment scheme based on software-defined networking. By using SDN, this scheme solves the problems such as low efficiency, complex management, and high operation cost in traditional data centers. This scheme has a simple architecture and can be easily deployed. After tested with some typical applications, such as load balancing and intra data center virtual machine migration, the availability of this scheme is presented. This scheme provides a valuable reference for data center network architecture.
