Abstract
A path is established through an optical communications network. One or more partial paths are evaluated according to a first criterion, and candidate end-to-end paths are then evaluated according to a second criterion. The end-to-end path evaluation disregards candidate end-to-end paths that include partial paths not meeting the first criterion. A path is established by selecting one of the candidate end-to-end paths on the basis of the second criterion.
