Research on the networking integration and evolution scheme of access laver SPN and PTN
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 research on the evolution of the access layer PTN to SPN network.Finally,a series of PTN equipment 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.
