Abstract
A routing method, performed by intelligent network elements of a data communications network having SONET applications, for selecting a path from a source network element to a next network element. Each network element has access to a database containing the addresses of its neighboring network elements and their types. To select a next network element, a routing network element first attempts to find a neighboring network element that is the same as the destination network element. If it has no such neighbor, the routing network element then attempts to find a neighbor that is in the same area as the destination, or failing such a neighbor, in the same routing domain. Optionally, the routing network element looks for a neighbor that has been selectively provisioned as a next network element. At each step, candidate network elements are eliminated by using data about their type and application to determine if they call for duplicate paths.
