To provide an optical IP network for establishing a path with the resource and the attribute of a subordinate layer taken into account.
An optical IP network is configured in a manner that a relay node apparatus 100 advertises resource / attribute information of a path of the subordinate layer, a sender node apparatus 200 generates second pass request information including a path request condition requested to a superordinate layer on the basis of the resource / attribute information and transmits the request information to the relay node apparatus 100. Further, the optical IP network is configured in a manner that the relay node apparatus 100 advertises resource / attribute detail information (characteristic detail information of attribute) of a path of the subordinate layer, the sender node apparatus 200 generates the second path request information including both a path request condition requested to the superordinate layer and a path request condition requested to the subordinate layer on the basis (by taking into account) of the resource / attribute detail information and transmits the request information to the relay node apparatus 100.
