Discussion on the evolution scheme of power communication network from PTN to SPN

Abstract

With the continuous development of the new power system, the broadband and isolation requirements of the power communication network are further increased. It is urgent to evolve the traditional PTN packet transmission network into SPN sliced transmission network with slicing capability. This paper proposes two networking schemes of service segment deployment and PTN OverLay SPN. Comparing the two schemes from the aspects of security, reliability, implementation complexity, operation and maintenance complexity, the paper analyzes the application scenarios of the two schemes and verifies the feasibility of the schemes through the actual scene test.
