A method for automatically getting optical network connection relation

Abstract

The invention discloses a method for automatically acquiring connection relation of an optical network, which includes the following steps: a connection relation information model for each optical interface of a veneer is formulated according to physical position of the veneer in a node; the veneer modulates the connection relation information model into an optical signal for transmission before transmitting the optical signal through an optical output interface of the veneer; when the optical signal is received through the optical input interface, the connection relation information model is analyzed; when the connection relation information model varies, the connection relation information model is actively reported to a control processing module of the veneer and the control processing module actively reports the updated connection relation information model to a network management system; and the network management system reveals internal connection relation of the node by means of a graphical or text data table. The technical proposal of the invention requires no artificial connection assignment; and at the same time automatically acquires the connection relation among the network resources and also provides support for automatic resource discovery in an intelligent optical network.

Description

technical field [0001] The invention relates to a method for realizing automatic acquisition of an optical network connection relationship, which belongs to the field of optical communication. In particular, it relates to a method for realizing automatic acquisition of network connection relations of an optical transmission network using WDM (Wavelength Division Multiplexing) technology. Background technique [0002] With the technical development and wide application of optical transport network, the requirements of network managers for the intelligence of optical network management system are also increasing. Therefore, the optical transport network management system has begun to change from the traditional network element level network management system (EMS, Element Management System) is evolving to a network-level network management system (NMS, Network Management system), and the architecture of optical transmission equipment is showing a development trend towards an i...
