Claim:
1. A path control method for controlling a communication path by selecting one path from among a plurality of path candidates with respect to a specific piece of traffic in a network constituted of a radio link provided with an adaptive modulation function, the method comprising: comparing a requested band of the piece of traffic, with an allocatable band allocatable to a first path candidate that is included in the plurality of path candidates and that satisfies a degree of stability requested by the piece of traffic by a first modulation method; and giving a penalty cost due to transmission using a band usable by a second modulation method whose degree of stability is lower than the first modulation method to the first path candidate so that the first path candidate is less likely to be selected, when the requested band of the piece of traffic is larger than the allocatable band as a result of the comparison, and selecting one path from among the plurality of path candidates.
