Method for generating signal flow graph

Abstract

The related method for signal flow graph comprises: taking regular distribution firstly, then adjusting according to inner cable information. This invention combines the advantages of rule and longest path distributions, eliminates effect from new added unit to original graph, and can ensure the graph integrality.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for generating a signal flow graph in the field of optical communication technology. Background technique [0002] WDM (Wavelength Division Multiplexing, wavelength division multiplexing) equipment can generally be divided into OTM (Optical Terminal Multiplexer, optical terminal multiplexing equipment), OLA (Optical Line Amplifier, optical line amplification equipment), OADM (Optical Add / DropMultiplexer, Optical add-drop multiplexing equipment), REG (Regeneration, electrical relay equipment), and different types of equipment have different internal signal flows. [0003] Taking OTM as an example, in the sending direction, OTM multiplexes STM-16 signals with a wavelength of λ1~λ16 (or λ32) into a WDM main channel through a multiplexer, then optically amplifies it, and adds a signal with a wavelength of λs Optical Supervisory Channel. In the receiving direction, the OT...
