1、某通信公司承载网IP化工程设计范本摘要2009年初,中国联通获得了 WCDMA 3G牌照,从此高速增长的3G新增用 户及其网络数据流量给中国联通原有数据传输承载体系带来了前所未有的压力。 中国联通也为此开展了多层次的网络承载改造。2009年初,原浙江联通与原浙江 网通合并成为了新浙江联通,这为联通提供了新的承载网支持,但也带来了原有 承载改造计划需求更换、网络兼容互通方面的问题,而这些都是以IT网络的融合 为基础。而新联通成立也为宁波联通建设新的核心承载网改造提供了契机。随着 业务需求与通信技术的进展,通信网的业务与网络融合已经成为通信网进展的要 紧方向。传统意义上的专有数据传输网网络正在逐步
2、演进成电信企业内部多应用的 综合数据网络平台。为了实现一个物理承载网承载多个逻辑独立的业务,NGN. IPoATM. MSLPVPN等各项技术被引入到网络建设中。本文通过论述核心承载网的特征与各项有关技术的原理,阐述了 NGN.MGW 等技术作为核心承载网IP化实现的核心技术的可行性,描述了浙江联通下辖的宁 波联通核心承载网结构的设计过程,全面说明了最终实现的方案与步骤,最后本 文总结了本次网络建设中的不足与对未来的展望。关键词: 承载网IP化,光传输网络,WCDMA, MPLS,传输系统改造AbstractThe WCDMA data transportation kept growing
3、with a rapidly high pace since China Unicom Corporation acquired the WCDMA operating license in early 2009, which came up with new system press and bearer requests on the original bearer network system. The network architecture distributed originally and network system expand gradually have become a
4、n important factor in network integration. The original Zhejiang Unicom Co, and previous Zhejiang Netcom Co, merged to form the new Zhejiang Unicom, which would provide a new bearer network support. However, there are problems such as requirements changes in original core-bearer system upgrade proje
5、cts, and there had been network compatibility issues to deal with. On the other hand, it is great chance to boost up the re-construction of core-bearer network in China Unicom, Ningbo branch.Legacy of idata only“ transmission network subsystem is rapidly playing the role as common network platform i
6、n telecommunication industry. Through the description of Zhejiang Unicom IP-based core bearer network design and implementation in this paper, demonstrating the feasibility of the network status, network structure and its implementation. A lot of technical, like NGN、IPoATM MSLP VPN are applied in ac
7、hieving the goal of managing multiple logically independent services with one bearer-network.By introducing the relevant technical means and support equipment, by introducing the major procedure in designing of the core bearer-network in Ningbo, a branch of Zhejiang Unicom, we will discuss the possi
