Problems solved by technology

It can be seen that the NNI data link bundling technology has been realized in the prior art. In contrast, due to the limitation of the function of UNI itself, the bundling function has not been realized for the UNI data link

Embodiment Construction

[0031] The basic idea of ​​the present invention is to detect the configuration operation state, configure the data link for different configuration operation states; determine the similarities and differences between the configured data link TNA and the configured data link TNA, and perform the corresponding data link according to the judgment result Bundling operation.

[0032] Here, the configuration operation status includes: adding, deleting, and modifying; the TNA is a globally unique address allocated by ASON for each UNI client, which is called the transport network allocation address. A TNA can identify one or more Data link, that is: if multiple data links belong to the same UNI client, the multiple data links are all identified by the same TNA, and the UNI client includes UNI-C node and UNI-N node , ASON configures corresponding TNAs for UNI-C nodes and UNI-N nodes; completing the configuration of the data link is to complete the configuration of the data link between ...

Abstract

The invention discloses an automatic binding method for automatically exchanging user-network interface UNI data link of optical-fiber network ASON, comprising the followings: configuration operating states are detected, and the data link is configured aiming at different configuration operating states; the similarities and differences between the transport network address TNA of the configured data link and the configured data link TNA are judged, and the corresponding binding operation is carried out on the data link according to the judgment result. The invention further discloses an automatic binding device of UNI data link of ASON simultaneously. The application of the method and the device can realize the automatic binding function of UNI data link of the same TNA so that each UNI client corresponds to one UNI binding link, thereby improving the resource management efficiency of the data link.

Description

Technical field [0001] The invention relates to an Automatic Switched Optical Network (ASON, Automatic Switched Optical Network) in a communication system, and in particular to a method and device for automatically bundling user-network interface (UNI) data links in ASON. Background technique [0002] The concept of ASON was formally proposed in 2001. ASON is an automatic switching transmission network based on Optical Transport Network (OTN). The main difference between ASON and traditional OTN is the introduction of an independent control plane. It is composed of multiple control nodes that are distributed in network element equipment and connected through signaling channels. The control plane has call control and connection control functions, including: routing functions, resource discovery functions, connection establishment, release, monitoring and maintenance functions, etc., so as to realize the intelligence of the optical network. [0003] ASON control plane interface incl...
