摘要： A method for restoring link failure and apparatus thereof, is used to restore the inter-domain failure. The method comprises: determining the upstream node and downstream node of the link with inter-domain link failure, enabling the local link restoration; implementing the local restoration for the link failure by taking the said upstream node and downstream node as source-destination nodes. As only the link between the upstream node and downstream node of the failed link is required to locally restored, thus the restored path can be dynamically calculated or preconfigured, as well as be resource reserved so as to achieve sharing the restoring bandwidth, and the restoring speed of inter-domain failure is greatly increased and the bandwidth is saved.

摘要： A Node reachability identification method, link identification method, route calculation method and Node address information diffusion method are provided, in which: When each Node in the Automatically Switched Optical Network (ASON) activates in the network, the Node address is converged and the converged address is fed up & fed down, the corresponding converged address is obtained by each Node and saved. After the activation of multi-hierarchy ASON, the Node address is converged and the converged address is fed up/fed down first, and then inter-domain link between each hierarchy is fed up. The invention enables each Node in the network to determine the reachability to any other Node in the network, thereby to calculate the route from source to destination, and to determine whether anyone of the TE (traffic engineering) link in the multi-hierarchy ASON is inner-domain link or inter-domain link.
