摘要: 近年来,随着云计算技术的飞速发展,数据中心网络作为底层基础设施,发挥着越来越重要的作用。数据中心网络能够为各种云计算环境提供良好的服务。 这几年 在研究云计算的同时,数据中心也是一个重要的研究热点。学习了一些新的拓扑结构,主要包括Fat-tree、DCell以及BCube等。而这些方案在系统扩展太快或者太慢的情况下,都在不同程度上有一些性能的瓶颈或者在路由以及结构的构建上有比较高的代价。提出了一个代价有效并且具有很强扩展性和容错性的数据中心网络——DCNS。其混合了DCell以及BCube的优点,避免了它们各自的缺点。之后提出了一个针对DCNS的容错路由机制。最后,使用一个合适的测试环境来测试该数据中心网络架构的有效性。实验表明,DCNS能较好地满足数据中心对网络结构的要求,并且能够保证系统的可用性。
