面向5G业务承载的新型智能城域网重构与思考

Reconstruction and Thinking of New Intelligent MAN for 5G Service Bearing

智能城域网模式的理念是基于网络的架构和协议实现对于通信云以及移动云的专一化发展。政府以及大企业基于固定的宽带业务作为实际的承载目标,具有SDN的智能化和自动化的模式方案体系,保证业务的快速发展和灵活的部署构建。随着5G技术的快速发展和完善,传统的典型模式也开始向着SDN模式发展,传统模式的IPRAN城域网以及IPRAN的回传网灵活性不足,新型业务的支撑性存在缺陷。为了满足5G业务承载和云网一体化的发展趋势,本文对新型城域网的网络重构和演变方向进行了分析。

The concept of intelligent MAN mode is to realizc thc specificdevelopment of comunication cloud and mobile cloud based on the network architecture and protocol.The goveriment and large eiterprises take the fixed broadband service as the actual bearing goal.and have the intelligent and automatic mode scheme system of SDN to ensure the rapid development of business and flexible deployment and construction.With the rapid development and improvement of 5g technology.the traditional typical mode also begins to develop towards SDN mode.The flexilility of the traditional mode IPRAN MAN and IPRAN return network is insufficient,aindi tle support of new services is defective.ln order to meet the development trend of 5g service carrving and cloud network integration.tliis paper analyzes the network reconstruction andd evolution direction of the new MAN.
