摘要
针对目前软交换的大规模建设及应用,AG不断的引入和建设,如何实现AG上连的业务承载是承载网领域迫切需要研究的课题。文章分析了NGN的体系结构和承载方案,深入阐述了城域网VPN、城域网SR延伸和MSTP传输网三种AG上连承载方案,提出了选择具体技术方案的建议。
With the large-scale construction and application of the softswitch and the continuous introduction and construction of AG, how to realize the service loadsupporting uplinked by AG becomes a most urgent subject for research in the field of loadsupporting network. This paper analyzes the architecture and loadsupporting schemes forNGN and discusses in detail the three kinds of schemes, namely, VPN in the Metropolitan Area Network, SR extension in the Metropolitan Area Network and MSTP transmission network. Suggestions for scheme choice are glven.
