| Abstract: | PTN is the developing direction of next generation optical transmission technology. Firstly, this article introduced MSTP, which is the mature mainstream application technology at present, and PTN; then, compared them from both technology principle and network implementation aspects. Secondly, it introduced several applicable scenarios for PTN and the evolution strategies from MSTP to PTN. Finally, according to the MAN construction requirements for mobile telecom operator, this article researched some PTN network implementation modes and carried on the analysis on these modes. |
