Abstract
A method used for establishing an optimized path between two endpoints in a transmission network including subnetworks is provided. In the method, two endpoints and route selection elements are specified, a first route search is performed to search for route candidates each of which connects subnetworks by using data on network resources according to the route selection elements, and the route candidates is stored in a dynamic routing table. Then, at least a route candidate is selected as a selected route candidate according to the route selection elements, and a second route search is performed to search for a route connecting network elements in each subnetwork on the selected route candidate.
