中国联通169网络SDN化改造的成果与经验
|
摘要
基于SDN技术,中国联通利用现有网络能力,以差异化保障为抓手,开放运营,以业务为驱动,推进C h i n a 1 6 9骨干网、城域网接入网、国际出口的S D N化部署。重点介绍了中国联通1 6 9网S D N化改造整体思路,相关的技术特点及方案优势。分析表明,该方案的创新有效提升宽带网络资源的利用率,挖潜网络价值,通过网络能力开放和合作,推动产业链健康发展。
Based on SDN technology, China Unicom utilizes the existing network capabilities to open its operation with differentiated guarantee as the starting point and to promote the SDN deployment of China 169 backbone network, metropolitan area access network and international exports driven by business. This paper focuses on the comprehensive thinking of SDN transformation of China Unicom 169 network, related technical features and the advantages of the solutions. The innovation of the solution effectively improves the utilization of wideband network resources, explores the value of network, and promotes the healthy development of the industry chains through the opening and cooperation of network capability.
