SDN业务设计与发展趋势

SDN Service Design and Development Trend

相对于当今的企业数据中心、校园和运营商环境的动态计算和存储需求来说,传统的网络架构已经不再满足需求了,而软件定义网络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。文章介绍了SDN的概念和其架构,着重阐释了SDN网关平台业务的设计方案,最后提出对SDN技术的趋势展望。

The traditional network architecture can no longer meet the dynamic computing and storage requirements of today’s enterprise data center, campus and operator environment.Software defined network(SDN) can break through the fixed limitation of hardware on network architecture, and effectively solve the demands of complex export equipment, diverse service demands and high requirements of uninterrupted service. This paper introduces the conceptof SDN and its architecture and focuses on the design of SDN network management platform services. Finally,the trend of SDN technology is prospected.
