SDN技术在混合云网络架构中的应用研究

Research on the Application of SDN to Hybrid Cloud Network Infrastructure

混合云在企业自有IT的基础上,构建与云端网络互联的混合IT基础架构。对运营商来讲,为企业提供混合云需要解决多租户网络虚拟化的问题,并提供虚拟网络间的弹性互联。分析了基于SDN技术实现混合云的2种主要方式,描述了每种方式的技术原理及架构。对2种方式的优缺点进行了比较。

Hybrid cloud constructs the hybrid IT infrastructure by connecting the enterprise’s on-premises IT and cloud networks. For op-erators, it needs to solve the problem of network virtualization and provide the flexibility interconnection among virtual net-works to provide the hybrid cloud service. It proposes two main methods of hybrid cloud network based on SDN technology, describes the technical principle and compares the advantages and disadvantages of the two methods.
