迎接IP宽带网络发展的新阶段

IP宽带网络的发展经历了三个重大阶段。我们目前面临着的是一个IP宽带网络大变革大发展的阶段，是一个电信业务转型以用户体验为核心的阶段。在这一阶段新的接入技术，FTTX、WiMAX，WiFi Mesh、3G和3GLTE等，带来了接入网革命性的改变。充足的带宽促使电信运营商尝试着重新夺回IP宽带网络带宽的端到端管控权以打造新型的互联网价值链，以优质的高速IP宽带网络掌握三网合一的主导权，让自己从单纯的带宽服务转型为全业务的信息供应商和服务商。本文就新一代IP宽带网络相关的网络技术和网络架构进行了细致的讨论，希望能够帮助电信营运商找到适合自己的平滑演进到新一代IP宽带网络、适应所处市场需求的创新业务增长途径和网络转型的时机和方式。

Moving to the New Dimension of IP Broadband Network

With new network access technologies such as FTTx, WiMAX, 3G LTE being deployed, Internct will take another bloom with many kinds of new bandwidth-hungry services taking fly such as triple-play, online video and online gaming, etc.. The IP broad- band network which carries the Internet will be moved into a new phase. In this new phase, Telecom Service Providers consider triple-play service could be the potential revenue source and are now proactively starting the service and network transformation to meet the challenge from voice revenue dropping, and the challenge from the OTT （Over-The-Top） Service Providers gaining massive business without any investments to network infrastructures. The IP broadband network technology and architecture to deliver Triple-play services have been discussed, which will help Telecom Service Providers to develop strategies of moving to the new dimension of IP broadband network.
