Claim 5:
6. A control method to be executed by a control apparatus configured to, in a network constituted by a plurality of communication apparatuses, control one or more anchor nodes designated in advance among the plurality of communication apparatuses, the control method comprising:
creating route information including labels of communication apparatuses or a links to be passed through, based on an input required condition;
dividing the labels included in the route information in units of anchor nodes, and compressing at least a portion of the labels included in the route information into a compressed label that can be expanded in at least one anchor node among the communication apparatuses determined based on the route information, so as not to exceed a processing limit of a communication apparatus determined based on the route information;
distributing information for expanding the compressed label to the at least one anchor node; and
merging compressed labels together in a range of not exceeding a processing limit of a communication apparatus determined based on the route information, and distributing information for expanding the merged compressed labels.
