Abstract:
A node device in an optical transmission network where a manually set path and an ADP (autonomous decentralized protocol) set path coexist, wherein the manually set path is set by centralized control and the ADP set path is set by autonomous decentralized processing, the node device including: a label memory for storing at least first labels used for manually set paths and second labels used for ADP set paths, wherein the first and second labels previously defined before path setting; and a resource manager for setting a manually set path and an ADP set path by referring to contents stored in the label memory.
