简要介绍了目前城域数据网络发展、现状和主要组网技术,分析了新运营者城域数据网在不同阶段需要解决的主要问题,并提出初期利用MSTP方式组建城域传输和数据网,最终将城域数据网分离独立组网的发展思路。最后介绍了新运营者在南方某省会城市初期合并建设MSTP城域传输网和数据网,以及演进为独立的城域MSTP传输网、NGN轻载数据网和纯数据网。
This paper briefly introduces the current development, status quo and main networking technologies of metro data networks. It analyzes the main problems that metropolitan area data network needs to be solved in different phases of metro operators and proposes the early formation of metro transmission and data networks by MSTP. Finally, The idea of separating the metro data network from the independent network. Finally, the new operators are introduced to merge and construct MSTP metro transport network and data network in the initial capital city of the south and to evolve into independent metro MSTP transport network, NGN light-load data network and pure data network.
