Abstract
Systems and methods for providing a network monitoring tool for appropriately grasping a setup state of a label switched path (LSP) in a network. A monitoring apparatus comprises a communication unit that communicates with a router among a plurality of routers in the network, and a collection unit that collects LSP path information via the communication unit. The LSP path information includes information maintained by the router. The monitoring apparatus also comprises a storing unit that stores state information based on the collected LSP path information, and a display unit that reads the state information for a selected LSP stored by the storing unit and graphically displays a path of the selected LSP, in accordance with a user's instruction.
