基于能力开放、集中控制、易于解耦的优势，SDN技术已经在数据中心等领域得到广泛应用，其应用场景在电信网络中也在不断扩展。分析了中国联通本地综合承载网的发展现状，针对其衍生出的简化运维、区分服务、能力开放等需求讨论了基于SDN技术的解决方案，对SDN技术在该网络中的引入与网络融合提出了若干思路。SDN在运营商网络中的引入是个循序渐进的过程，应该始终关注解决现网实际问题，并尽量减少网络演进与融合过程中的投资成本。

Based on the advantage of capability opening centralized control and easy decoupling,SDN technology has been widely used in data center network,and it is extending its application in other telecom network areas. It firstly analyzes the development status of China Unicom’s local unified transport networks. Then the network problems and relevant SDN solutions like simpli-fying O&M,different serving,and capability opening are discussed. Final y,the introduction and convergence technology of SDN and practical networks are given and explained. It concludes that the introducing SDN into operator’s network should be incremental and should focus on solutions of practical networks. The CAPX during SDN introducing should be reduced at most.
