Abstract
Official abstract text for this publication.
The present invention provides a method and apparatus for automatically restoring node resource state in the Dense Wavelength Division Multiplexing Based Automatic Switched Optical Network (WSON) system. This method comprises the following steps: using each node in the WSON system as an initiation node and notifying the resource state of the initiation node to a neighboring node; the neighboring node comparing the received resource state of the initiation node with the resource state of the present end; and under the condition that the resource state of the initiation node and that of the neighboring node are inconsistent, according to the actual resource state, determining one of the initiation node and the neighboring node to be the node whose resource is occupied, and automatically releasing the resource of the node. The present invention also provides an apparatus for automatically restoring node resource state in the WSON system. The present invention can effectively detect the problem of inconsistent wavelength resource in the WSON system caused by abnormal status, and can automatically correct the resource state information, release the link bandwidth resource occupied incorrectly, at the same time enhance the fault-tolerant capability and the stability of the WSON system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for automatically restoring node resource state in a Dense Wavelength Division Multiplexing Based Automatic Switched Optical Network (WSON) system, comprising the steps of: using a node in the WSON system as an initiation node, regularly sending packed resource state of the initiation node to a neighboring node; the neighboring node comparing the received resource state of the initiation node with resource state of the neighboring node; and…
