Abstract
In a packet relaying apparatus, a label distribution protocol processor performs a label assignment so that labels which a label management portion of its own processor manages and which the label management portion of an adjoining packet relaying apparatus manages are assigned in mutually reversed orders within a label available range when a directionality is determined to be unidirectional. In addition, an incoming label and an outgoing label assigned to a unidirectional FEC can be used as the outgoing label and the incoming label assigned to another FEC opposite in direction to the former FEC.
