Abstract: In view of the current SDH network service carrying status and private line service carrying demand, firstly, the characteristics of the current mainstream transport network technology are described, and the migration scheme of carrying services on SDH network is studied. Then, a government-enterprise private network carrying scheme based on VC-OTN technology is proposed. The application scheme of VC-OTN technology is constructed from the aspects of network structure planning and network evolution to solve the problems existing in SDH service migration and network evolution. Finally, an alternative scheme for SDH network is proposed to achieve the goal of SDH network cooperative evolution and smooth service migration.
