Jinkai Tang, Qi Zhang. Introduction and Application Analysis of SDN in PTN[J]. Telecommunications science, 2015, 31(12): 1-200. DOI: 10.11959/j.issn.1000-0801.2015266.
statistical multiplex and centralized network management
PTN plays an important role in a carrier network. SDN is developing quickly
having the characters of intel-controlling
centralized controlling and source-opened. Based on the characters
the necessity of the introduction SDN to PTN and application scenarios of base station and private line were discussed. Technical requirements of SPTN were proposed and the basic functions of SDN with the result of SPTN testbed in Shanghai CMCC were implied. Finally
the evolution road of transferred layer and controller layer in carrier network after the introduction of SDN was discussed.
