摘要
目前,国内运营商的承载网络已普遍实现IP化,IP承载网络具有端到端Qo S、统计复用和集中网管等多种优异特性;而SDN具有智能控制、集中控制和开源的技术特征,结合SDN技术特点和基本功能在运营商IP承载网的试点应用,分析了SDN引入运营商IP承载网的应用价值、实施的可能性和必要性,以及对运营商未来网络架构发展的影响,并思考演进方向。
At present,IP has achieved universal carrying network of domestic operators,IP bearer network has many excellent characteristics such as end to end QoS,statistical multiplexing and centralized network management.SDN has the characteristics of intelligent control,centralized control and open source.Combined with the basic functions and technical features of SDN bearing network operators in the pilot application IP analysis,this paper analyzes the application value,the possibility and necessity of implementation of SDN introduced carrier IP bearer network,and the influence on the future network architecture of operators,and considers the evolution direction.
