Abstract
Information that is not dependent on how a GMPLS switch or an MPLS router is set up (information independent of the type of GMPLS switch or MPLS router) is used to obtain attribute values of communication paths and manage communication path configurations in a communication network. Provided is a communication path management system for managing a communication network system in which a communication path is established by transferring communication path establishment control information between data switching apparatuses, including: an information collecting module which collects the communication path establishment control information; an information accumulating module which accumulates the communication path establishment control information collected by the information collecting module; and an information searching module which searches the communication path establishment control information accumulated by the information accumulating module, wherein which communication path is established is derived from the communication path establishment control information searched by the information searching module.
