中文摘要:
      本文讨论了在弹性光数据中心(DC)网络中实现高效的大数据应用数据迁移和备份的技术。我们首先描述大数据应用对底层网络基础设施的影响,并介绍柔性网格弹性光互连网络的概念。然后在动态选播等网络中对数据迁移进行建模,并提出了几种有效的算法。为了实现高效的数据备份,我们利用相互备份模型,研究如何通过最小化DC备份窗口来避免对DC正常运行的负面影响。
英文摘要:
      techniques for ercient data migration and backup of big data applications in elastic optical data center (DC) networks is the main topic of This article. First of all, we describe the impact of big data applications on the underlying network infrastructure and introduce the concept of ?exible grid elastic optical interconnect networks. Then, data migration is modeled in network such as dynamic anycasting, and several e?ective algorithms are proposed. In order to achieve e?cient data backup, we use the mutual backup model to study how to minimize the negative impact on the normal operation of the DC by minimizing the DC backup window.
