An Overhead Processing Model for OCh-level OAM

摘要

The widespread use of DWDM technology has presented service providers with a new challenge: how to manage increasing optical channels (OChs) to provide fast, reliable services to their end customers cost effectively. OCh-level operation, administration and maintenance (OAM) function in optical are important to effective management, and digital wrapper can provide these functions. In this paper, we propose an ITU-T Rec. Draft G.709 and G.798 based overhead processing model for OCh-level OAM.
