A study of service layer function requirement based on intelligent optical network

In this paper, The Next Generation Optical Network Service Platform(NGOSP) based on the architecture of ASON was studied. The paper presented the layered concept of service function around the telecommunication service requirement base on the analysis for the evolution trend of service optical network and modes of service provision, and definitized the reference model and constructed the function framework of service optical network. The general function components also were abstracted from service perspective and a thought of mapping function of service layer to network technical layers was presented.
