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

[0040] The basic idea of ​​the present invention is: detect configuration operation status, configure data link according to different configuration operation status; Bundle operations.

[0041]Here, the configuration operation status includes: adding, deleting and modifying; the TNA is a globally unique address assigned by ASON for each UNI client, called the address assigned by the transport network, and a TNA can identify one or more Data link, that is: if multiple data links belong to the same UNI client above, then the multiple data links are identified by the same TNA, and the above UNI client includes UNI-C nodes and UNI-N nodes , ASON configures the corresponding TNA for the UNI-C node and the UNI-N node respectively; completing the configuration of the data link is completing the configuration of the data link between the UNI-C node and the UNI-N node, that is: completing the data link in Configurations on both sides of the UNI-C node and the UNI-N node.

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, in particular to a method and device for automatically binding user-network interface (UNI) data links in the ASON. Background technique [0002] The concept of ASON was officially 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 that it introduces an independent control plane. It consists of multiple control nodes distributed in network element devices and connected through signaling channels. The control plane has call control and connection control functions, including: routing function, resource discovery function, connection establishment, release, monitoring and maintenance functions, etc., thus realizing the intelligence of the optical network. [0003] The ASON control plane interface includes UN...
