Abstract

This invention discloses a signal dispacth method in an optical transmission network including: converting received signals to electric signals to be de-imaged and adapted to a unified particle grade to be processed with asynchronous cross dispatch in an asynchronous cross matrix. This invention also discloses a system including: a photoelectric conversion unit, a de-image unit, an adaptive device, in which, the asynchronous cross matrix receives optical signals to be converted into electric signals by the photoelectric conversion unit to be input into the de-image unit then enters into the adaptive device to be processed and output in a unified particle grade, then enters into the asynchronous cross matrix to be dispatched.

Description

Technical field

[0001] The present invention relates to a signal scheduling technology in an optical transport network (OTN), in particular to a method and system for realizing signal scheduling in an OTN. Background technique

[0002] Optical transmission system (OTH) technology is a new generation transmission system after Synchronous Digital Hierarchy (SDH) / Synchronous Optical Network (Sonet). The advantage of the OTN network is to meet the explosive development requirements of data bandwidth. It is a transparent transmission technology developed for the large-capacity and coarse-grained scheduling requirements of the backbone network level, and adopts digital encapsulation technology.

[0003] In order to realize the data transmission in OTH, the International Telecommunication Union Standards Department (ITU-T) G.709 recommends defining the optical data unit (ODUk), where k=1, 2, 3, as three levels of connection signals, and the rates are respectively for:
