Claim 0:
1. 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 apparatus comprising:
a route creation unit configured to create route information including labels of communication apparatuses or links to be passed through, based on an input required condition;
a route compression unit configured to divide the labels included in the route information in units of anchor nodes, and compress 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; and
a distribution unit configured to distribute information for expanding the compressed label to the at least one anchor node,
wherein the route compression unit is configured to merge compressed labels together in a range of not exceeding a processing limit of a communication apparatus determined based on the route information, and the distribution unit is configured to distribute information for expanding the merged compressed labels.
