面向业务和网络协同的未来IP网络架构演进

IP技术作为互联网的技术基础，在今后5～10年如何发展是通信行业面临的关键问题。分析了传统IP网络架构的成功与不足，提出未来IP网络既要继承传统IP技术的设计原则，比如端到端原则和分层解耦原则，又要解决现有IP网络中业务和网络过于割裂的问题。从网络演进和未来业务需求的角度出发，认为未来IP网络的核心问题是要加强业务和网络的协同，提出了改进后的IP网络设计原则“横向：服务化网络赋能的端到端架构，纵向：智能控制面支撑的分层模型”，并且基于此原则提出了未来网络的参考架构。

Future IP network architecture evolution for service and network collaboration

As the technical foundation of the internet, how IP technology develops in the next 5 to 10 years is the key issue facing the communication industry.The success and weakness of the traditional IP network architecture were analyzed, and the future IP network should not only inherit the design principles of the traditional IP technology was proposed, such as the end-to-end principle and layered decoupling principle, but also solve the problem that the service is too separated from the network.From the perspective of network evolution and future service requirements, the core issue of future IP networks is to strengthen the collaboration of between services and networks , and the improved IP network design principle “horizontal: end-to-end principle empowered by service-oriented network, vertical: layered model supported by intelligent control plane” was proposed, and based on this principle, the reference architecture of the future network was proposed.
