云网协同时代运营商IP承载网发展

IP承载网作为Internet的重要基础设施,在云网协同发展背景下其作用越发重要.万物互联时代,IP承载网的演进逐步从以网络扩展为中心向以用户为中心转变.在对运营商IP承载网络现状分析的基础上,结合业务与技术研究,提出了基于“体验圈”的网络发展思路.“体验圈”从流量的区域汇聚特性切入,以用户体验为核心对架构进行优化,同时,对传输层以及应用层的协同提出建议.

Development of carrier's IP bearer network in cloud-network coordinated era

IP bearer network is one of the basic internet infrastructures.It plays a more and more important role in the cloud-network coordinated era.Entering the era of everything interconnected,the IP beaer network evolution has changed from network-centrie to user-eentrie.Combined the current situation of the IP bearer network with the research of related technologies and service,some suggestions on IP bearer network development based on the concept of“experience circle” were given.The “experience circle” concept came from the research on traffic regional aggregation,which offered a way to optimize the IP bearer network based on user's experience,as well as suggestions on IP-transport synergy and application coordination.
