分组传送网规划策略和探讨

Planning strategy and discussion of PTN

对现网业务的发展和未来网络的需求变化做出论述,引入分组传送网的建设必要性。从核心层、汇聚层、接入层3个层面,探讨了分组传送网网络结构。从网络收敛比设置、路由域划分方面介绍了分组网络的新变化和规划策略,从设备选型和网络配套方面得出了新建网络中需要注意的问题。最后,对新建网络的维护和定位进行探讨,得出了分组传送网和其他网络的关系。

Development of existing network and changes of network in the future is discussed, and the construction necessity of PTN is introduced. From core layer, distribution layer, access layer,it probes into the network packet transmission network structure. The new changes and planning strategies of PTN are introduced from network convergence setting and routing domain partition areas. Problems that need to be mentioned in the new network were obtained from equipment selection and network support areas. Maintenance and positioning of new network was investigated lastly, and the relationship of PTN and other networks was obtained.
