Abstract
In an apparatus and method of selecting a label switched path (LSP) in a network management system, a status analyzing unit analyzes and digitizes performance information, fault occurrence, and fault history of a link. A link weight managing unit which determines link weight values using a predetermined weight calculation algorithm on second constraints that corresponds to qualitative information related to performance analysis of a path. An LSP selecting unit selects a path, from among paths on a path list, that satisfies first constraints which corresponds to objective information related to a path selection required by the administrative network policy, and, when there are several selected paths, selects a path that minimizes expense using the link weight values.
