<p>A hierarchical routing query method of Automatic Switched Optical Network, applies to the network including multiple layers of routing domain, after the routing controller RC of the children domain receives the routing query request, if it can not calculate the entire route, then it sends the routing query to the RC of the father domain; if the RC of the father domain can not calculate the entire route, then it further communicates with other children domains; after it obtained the entire route, it sends the route query response back to the requester. The present invention solves the routing query problem of creating the cross-domain connection in the Automatic Switched Optical Network.</p> |
