摘要
传统网络出口架构有易发单点故障、性能瓶颈、功能固化等缺点。作为基于软件的网络架构,通过提升网络可编程能力,SDN能突破硬件对网络架构的固化限制,并有效解决数据中心出口设备复杂、服务需求多样、不间断服务要求高等诉求。SDN作为新的开放网络架构被应用到数据中心出口场景时,我们需做好业务需求数据流分析、制定详细设备接口连接方案、基于OpenFlow开放协议配置流表策略、创建服务链、制定包代理策略等工作,以最终建立可靠、灵活、可视化且具有扩展性的数据中心出口架构。
The traditional network export architecture has shortcomings such as being prone to single point of failure, performance bottlenecks and functional solidification. As a software-based network architecture, by improving the programmability of network, SDN can break through the hardware’s solidified restrictions on the network architecture and effectively solve the problems of complex data center export equipment, diverse service requirements, high requirements for uninterrupted service and so on. We shall do business demand data flow analysis, formulate detailed device interface connection solutions, configure flow table strategy based on OpenFlow open protocol, create service chain and develop package agent strategy when SDN is applied on data center export scenarios as a new open network architecture, so as to realize the data center export architecture with reliability, flexibility, visualization and scalability.
