云数据中心网络架构设计

Network Architecture Design of Cloud Data Center

云计算和虚拟化技术的发展,促进了数据中心的变革,从提供主机托管、机位、带宽出租等传统业务到云主机、云存储、云资源的出租,云数据中心需要为用户提供更加灵活高效的服务,因此也对数据中心的网络架构提出了更高要求。通过采用100G以太网技术、网络虚拟化技术等实现云数据中心的网络扁平化,减少网络节点,可提高网络可靠性和可扩展性,为用户提供更加流畅的信息服务。

The development of cloud computing and virtualization technologies, promote the transformation of the data center, form traditional business （such as web hosting, the rental machine-position and bandwidth） to cloud hosting, cloud storage and cloud resources for rent. Cloud data center has to provide users with more flexible and efficient service ability. The ability puts forward higher requirements for network architecture of data center. By adopting 100 Gigabit Ethernet technology and network virtualization technology, it can flat network of the cloud data center, reduce the network node, improve the reliability and scalability of the network and provide users with more fluent information services.
