PATH SETTING METHOD, NODE DEVICE, AND MONITORING CONTROLLER

摘要

PROBLEM TO BE SOLVED: To solve the problem wherein a GMPLS loaded node can not control a non-GMPLS loaded node in a network, where GMPLS loaded nodes and non-GMPLS loaded nodes are intermingled.

SOLUTION: A GMPLS loaded node 230 performs hold processing of GMPLS control when the GMPLS control is started, and transmits a GMPLS control start message to a monitoring controller 251. The monitoring controller 251 determines existence of non-GMPLS loaded node on a LSP (Label Switching Path) to be controlled by GMPLS control. If a non-GMPLS loaded node exists, the monitoring controller 251 transmits a GMPLS control hold release message and resumes the GMPLS control, after carrying out all of settings necessary for a non-GMPLS loaded node 231.
