Embodiment Construction

[0022] In order to solve the disadvantages of the traditional technical solution, the present invention further elaborates the implementation method of the automatic acquisition of the optical network connection relationship described in the present invention through the following specific examples. limited.

[0023] Each node in the optical transport network is composed of boards that implement different functions. Different boards inside and between nodes are connected through optical fiber interfaces. The internal structure of each functional board is as follows: figure 1 Shown:

[0024] from figure 1 It can be seen that the functional veneer described in the embodiment of the present invention includes the following components:

[0025] The optical interface 101 can be further divided into an optical input interface and an optical output interface according to the flow direction of the optical signal, which are respectively used as physical interfaces between the boards ...

Abstract

The invention discloses a method for automatically obtaining the connection relationship of an optical network, comprising: formulating an information model of the connection relationship of each optical interface of the single board according to the physical position of the single board in the node; Before, the connection relationship information model is modulated into the optical signal and sent; when the optical signal is received through the optical input interface, the connection relationship information model is analyzed; when the connection relationship information model changes, it is actively reported to the single board control processing module, and the control The processing module actively reports the updated connection relationship information model to the network management system; the network management system displays the internal connection relationship of nodes in the form of graphics or text data tables. The above-mentioned technical solution of the present invention does not need manual connection assignment; at the same time, the automatic acquisition of the connection relationship between network resources also provides support for automatic resource discovery in the 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...
