摘要
运营商网络重构的基本技术思路是以DC为核心进行建设。在现网规模试商用经验总结基础之上,提出了三级DC架构、统一通信云基础设施部署、城域网v BRAS资源池和转控分离方案。并从业务角度出发,提出城域网业务率先从大会话小流量和IPTV场景切入,从而加快运营商城域DC的建设,培养运营商ICT融合运维能力,切实推动城域网重构有序进行。
Evolving the legacy network to SDN/NFV network is the strategy of carrier network re-architecture. Based on large-scale cases, multi-tier data centers architecture, application-driven telecom cloud infrastructure, v BRAS pool and C-U separation solutions were proposed. Session-consumed services and IPTV are the first several services that can be implemented by the new solution in MAN. And in those usecases, the carriers＇ operators really combine the IT and CT operation teams into one virtual team, and push the evolution gradually.
