摘　　要：基于SPN和PTN两张传送网络共存,如何实现PTN与SPN的有效融合是当前网络发展的重要课题。文章首先运用中心接入点的策略来规划接入层SPN目标网蓝图,其次采用由下而上思路开展接入层PTN向SPN网络演进研究,最后通过八种接入层SPN与PTN组网融合场景进行了一系列PTN设备的迁移及业务割接操作,有效解决SPN和PTN组网融合、统一网络承载难题。Based on the coexistence of SPN and PTN transport networks,how to achieve effec-tive integration of PTN and SPN is an important issue in the current network development.Firstly,the strategy of the central access point is used to plan the blueprint of the SPN target network at the access layer.Secondly,the bottom-up thinking is adopted to perform rescarch on the evolution of the access layer PTN to SPN network.Finally,a series of PTN cquipment mi-gration and service cutting operations are carried out through eight scenarios of access layer SPN and PTN networking integration,effectively solving the problem of SPN and PTN networking integration and unified network bearer.
